QUESTION
Java @Override equals(): When this.getClass() != o.getClass() fails but shouldn't
Asked 2022-Apr-17 at 12:25I have this @Override for equals() in my MyClass class:
1public class MyClass extends MySuperClass
2{
3 ...
4 @Override
5 public boolean equals( Object o )
6 {
7 if ( this == o )
8 {
9 return true;
10 }
11 if ( o == null || this.getClass() != o.getClass() )
12 {
13 return false;
14 }
15 if ( !super.equals( o ) )
16 {
17 return false;
18 }
19 MyClass that = ( MyClass ) o;
20 return this.var1.equals( that.var1 ) && this.var2.equals( that.var2 );
21 }
22 ...
23}
24Pretty standard. Matter of fact, it follows Java best practices.
Later in life I have this in another sub-package class (my controller class):
1public class MyClass extends MySuperClass
2{
3 ...
4 @Override
5 public boolean equals( Object o )
6 {
7 if ( this == o )
8 {
9 return true;
10 }
11 if ( o == null || this.getClass() != o.getClass() )
12 {
13 return false;
14 }
15 if ( !super.equals( o ) )
16 {
17 return false;
18 }
19 MyClass that = ( MyClass ) o;
20 return this.var1.equals( that.var1 ) && this.var2.equals( that.var2 );
21 }
22 ...
23}
24...
25package com.a.b.api.controllers;
26...
27import com.a.b.jpa.models.MyClass;
28...
29MyClass myObject1 = new MyClass( var1, var2 );
30MyClass myObject2 = this.myClassRepository.getById( 1 ); // SpringBoot/Jpa/Hibernate
31
32if ( myObject2.equals( myObject1 ) )
33{
34 ...do something...
35}
36...
37this.myClassRepository.save( myObject1 );
38...
39My problem is that the .equals() is always failing here:
1public class MyClass extends MySuperClass
2{
3 ...
4 @Override
5 public boolean equals( Object o )
6 {
7 if ( this == o )
8 {
9 return true;
10 }
11 if ( o == null || this.getClass() != o.getClass() )
12 {
13 return false;
14 }
15 if ( !super.equals( o ) )
16 {
17 return false;
18 }
19 MyClass that = ( MyClass ) o;
20 return this.var1.equals( that.var1 ) && this.var2.equals( that.var2 );
21 }
22 ...
23}
24...
25package com.a.b.api.controllers;
26...
27import com.a.b.jpa.models.MyClass;
28...
29MyClass myObject1 = new MyClass( var1, var2 );
30MyClass myObject2 = this.myClassRepository.getById( 1 ); // SpringBoot/Jpa/Hibernate
31
32if ( myObject2.equals( myObject1 ) )
33{
34 ...do something...
35}
36...
37this.myClassRepository.save( myObject1 );
38...
39if ( o == null || this.getClass() != o.getClass() )
40because java says that this.getClass() and o.getClass() are NOT equal. When I debug the code (in Intellij IDEA 2022.1 UE) I see this:
this.getClass() = MyClass@13706
but
o.getClass = com.a.b.jpa.models.MyClass@8f7462
But they are the same class! Almost every Java book, tutorial, blog, Intellij IDEA, etc. demonstrates the .equals() this way. I have tried this in Ubuntu 20.04.4 LTS java-14-openjdk-amd64 and java-17-openjdk-amd64 with the same results.
What am I doing wrong?
ANSWER
Answered 2022-Apr-14 at 15:31myObject2 is an instance of a proxy class, generated at runtime by Hibernate using Byte Buddy. The generated proxy intercepts all method invocations, that's why getClass() returns different results.
As an alternative to getClass(), using instanceof might be another approach:
1public class MyClass extends MySuperClass
2{
3 ...
4 @Override
5 public boolean equals( Object o )
6 {
7 if ( this == o )
8 {
9 return true;
10 }
11 if ( o == null || this.getClass() != o.getClass() )
12 {
13 return false;
14 }
15 if ( !super.equals( o ) )
16 {
17 return false;
18 }
19 MyClass that = ( MyClass ) o;
20 return this.var1.equals( that.var1 ) && this.var2.equals( that.var2 );
21 }
22 ...
23}
24...
25package com.a.b.api.controllers;
26...
27import com.a.b.jpa.models.MyClass;
28...
29MyClass myObject1 = new MyClass( var1, var2 );
30MyClass myObject2 = this.myClassRepository.getById( 1 ); // SpringBoot/Jpa/Hibernate
31
32if ( myObject2.equals( myObject1 ) )
33{
34 ...do something...
35}
36...
37this.myClassRepository.save( myObject1 );
38...
39if ( o == null || this.getClass() != o.getClass() )
40if ( !(this instanceof MyClass && o instanceof MyClass) )
41{
42 return false;
43}
44However keep in mind that instanceof has its drawbacks. It violates the symmetry principle.
You shouldn't compare these objects in the first place, since a new object should be different from a Hibernate managed one that has a persistent state.
QUESTION
Hibernate JOIN [some entity] ON unexpected token
Asked 2022-Apr-02 at 10:11I use Hibernate 5.4.32.Final, when I try to execute this query via spring data:
1@Query("select new some.package.dto.TwoFieldDto(o.gln, u.email) "
2 + "from OrganizationEntity o "
3 + "join UserEntity u on u.organization.id = o.id "
4 + "where o.gln in (:glnList)")
5 List<TwoFieldDto<String, String>> findEmailListByGlnIn(List<String> glnList);
6On starting application Hibernate throw SyntexException when it reaches to UserEntity token, and gives out unexpected token.
If I try to execute query from the UserEntity side, query compiles successfully. (Yes, I haven't get a link from OrganizationEntity to UserEntity)
Is this Hibernate version not supported JOIN ON syntex? (OrganizationEntity doesn't contain link on UserEntity, but UserEntity has it).
ANSWER
Answered 2022-Apr-02 at 10:11The @Queryannotation expects JPQL by default which has its own syntax. As far as I know, you can not do someting like JOIN .. ON in JPQL .
I do not know the association between your entities but it should look someting like this:
1@Query("select new some.package.dto.TwoFieldDto(o.gln, u.email) "
2 + "from OrganizationEntity o "
3 + "join UserEntity u on u.organization.id = o.id "
4 + "where o.gln in (:glnList)")
5 List<TwoFieldDto<String, String>> findEmailListByGlnIn(List<String> glnList);
6@Query("select new some.package.TwoFieldDto(o.gln, u.email) "
7 + "from OrganizationEntity o "
8 + "join o.UserEntity u "
9 + "where o.gln in (:glnList)")
10But for that to work, there has to be an association between OrganizationEntity and UserEntity.
As an alternative you can always use a native query, where you could do a JOIN .. ON in your native SQL dialect:
1@Query("select new some.package.dto.TwoFieldDto(o.gln, u.email) "
2 + "from OrganizationEntity o "
3 + "join UserEntity u on u.organization.id = o.id "
4 + "where o.gln in (:glnList)")
5 List<TwoFieldDto<String, String>> findEmailListByGlnIn(List<String> glnList);
6@Query("select new some.package.TwoFieldDto(o.gln, u.email) "
7 + "from OrganizationEntity o "
8 + "join o.UserEntity u "
9 + "where o.gln in (:glnList)")
10@Query(value = "SELECT ....", nativeQuery = true)
11But this should only be an option if you are sure that you can not do it with JPQL.
QUESTION
Does hibernate set back reference in @OneToMany @ManyToOne relationship automatically?
Asked 2022-Feb-13 at 16:26I have Order entity that has orderItems list.
1@OneToMany(mappedBy ="order")
2List<OrderItem> orderItems;
3OrderItem has back reference to Order
1@OneToMany(mappedBy ="order")
2List<OrderItem> orderItems;
3@ManyToOne
4Order order;
5When I save Order should I manually set backreference in OrderItem entity?
Like this
1@OneToMany(mappedBy ="order")
2List<OrderItem> orderItems;
3@ManyToOne
4Order order;
5OrderItem orderItem1 = new OrderItem( //constructor );
6OrderItem orderItem2 = new OrderItem( //constructor );
7List orderItems = Arrays.asList(orderItem1, orderItem2);
8Order order = new Order( orderItems);
9
10orderItems.forEach(orderItem -> orderItem.setOrder(order); // like this?
11Do Hibernate and Spring data jpa set it automatically?
ANSWER
Answered 2022-Feb-13 at 16:26For creating and updating case , they will not help you to set it automatically and you have to configure the relationship by yourself.
The mappedBy here is to define whether Order.orderItems or OrderItem.order is to used to provide the value for the corresponding DB column that link between them. (i.e. order_id column in order_item table).
If mappedBy is defined , OrderItem.order will be used to provide the value for the relationship. Otherwise , Order.orderItems will be used.
For the loading case , it will help you to set it automatically.
QUESTION
Java 17: Maven doesn't give much information about the error that happened, why?
Asked 2022-Feb-04 at 20:28I'm upgrading from JDK 8 to JDK 17 and I'm trying to compile with mvn clean install -X -DskipTests and there's no information about the error.
Btw, I'm updating the dependencies and after that I compile to see if has errors. I need to update some dependencies such as Spring, Hibernate etc. I already updated Lombok.
I added the -X or -e option but I got the same result.
What can I do to get more information about the error? The log shows that it was loading hibernate-jpa-2.1-api before failed... so that means the problem is in this dependency?

ANSWER
Answered 2021-Oct-19 at 20:28This failure is likely due to an issue between java 17 and older lombok versions. Building with java 17.0.1, lombok 1.18.20 and maven 3.8.1 caused a vague "Compilation failure" for me as well. I upgraded to maven 3.8.3 which also failed but provided this detail on the failure:
java.lang.NullPointerException: Cannot read field "bindingsWhenTrue" because "currentBindings" is null
Searching for this failure message I found this issue on stackoverflow leading me to a bug in lombok. I upgraded to lombok 1.18.22 and that fixed the compilation failure for a successful build.
QUESTION
What should I replace the hibernate deprecated @TypeDef and @Type annotations by?
Asked 2022-Jan-18 at 14:13I've just upgraded the version I use for Hibernate to 5.6.1 and it seems it's now deprecating some Type-related annotations:
1@TypeDef(name = "json", typeClass = JsonBinaryType::class)
2
3
4@Type(type = "json")
5I found no documentation as to what to do except that
6.0 will introduce a new series of type-safe annotations to serve the same purpose
Our quality guidelines forces us to try and solve every warning and as such I would like to replace these annotations by a non deprecated use.
ANSWER
Answered 2022-Jan-18 at 14:13It seems there is no replacement until Hibernate 6. Type and also TypeDef was marked as deprecated to mark it as removed in version 6, but so far not replacement exists. The ideology here is that deprecated does not indicate that already a new version exists, which might be not an intuitive meaning for most developers.
This was reverted now in the current 5.6.3-Final version series.

I didn't find the problem of the query, anybody have the solution to solve this ?
ANSWER
Answered 2022-Jan-06 at 14:53The problem is that in H2 there are not explicit procedures or functions as you are trying defining.
For that purpose, H2 allows you to create used defined functions instead. Please, consider reed the appropriate documentation.
Basically, you create a user defined function by declaring an ALIAS for a bunch of Java code.
For example, in your use case, your CREATE_PROCEDURE_INITPSEUDOS could look similar to this:
1 /**
2 * @param connection the connection to set
3 */
4 public static void setConnectionHibernate() {
5 Properties connectionProps = new Properties();
6 connectionProps.put("user", "sa");
7 try {
8 Class.forName("org.h2.Driver");
9 } catch (ClassNotFoundException e) {
10 e.printStackTrace();
11 }
12 url = "jdbc:h2:mem:db1;DB_CLOSE_DELAY=-1;MODE=MySQL;";
13 }
14 static final String CREATE_PROCEDURE_INITPSEUDOS = "CREATE OR REPLACE PROCEDURE init_pseudos (MaxPseudo INT) BEGIN WHILE MaxPseudo >= 0 DO"
15 +
16 " INSERT INTO Pseudos (indexPseudo)" +
17 " VALUES (MaxPseudo);" +
18 " SET MaxPseudo = MaxPseudo - 1;" +
19 " END WHILE;" +
20 " END init_pseudos;";
21 public static void initBaseDonneePseudos() {
22 try (Connection connection = DriverManager.getConnection(url, connectionProps);
23 Statement stmt = connection.createStatement()) {
24 stmt.execute(RequetesSQL.CREATE_TABLE_PSEUDOS);
25 stmt.execute(RequetesSQL.CREATE_PROCEDURE_INITPSEUDOS);
26 stmt.execute(RequetesSQL.CREATE_FUNCTION_RECUPEREPSEUDO);
27 stmt.execute(RequetesSQL.INIT_TABLE_PSEUDOS);
28 } catch (SQLException e) {
29 e.printStackTrace();
30 }
31 }
32 @Nested
33 class BaseDonneeInteractionTest {
34
35 @BeforeEach
36 public void setUp() {
37 BaseDonnee.setConnectionHibernate();
38 }
39

41 void testInitBaseDonnee() {

51void init_pseudos(final Connection conn, final int maxPseudo) throws SQLException {
52 try (Statement stmt = conn.createStatement()) {

54 stmt.execute("INSERT INTO Pseudos (indexPseudo) VALUES (MaxPseudo);");
55 maxPseudo = maxPseudo - 1;
56 }
57 }
58}
59$$;
60Note the following:
- As I said, you define a user defined function as Java code. That Java code should be enclosed between two
$$delimiters. - Although I included explicitly some imports, you can use any class in the
java.utilorjava.sqlpackages in your code. If you want to included explicitly some imports, or if you require classes from other packages than the mentioned, the corresponding imports should be provided right after the first$$token. In addition, you need to include@CODEthe signal H2 where your imports end and your actual Java method starts. - If you need a reference to a
Connectionto the database in your code, it should be the first argument of your method. - Prefer to raise and not hide exceptions: it will allow your transactions to be committed or rollbacked as a whole appropriately.
You can invoke such a function as usual:
1 /**
2 * @param connection the connection to set
3 */
4 public static void setConnectionHibernate() {
5 Properties connectionProps = new Properties();
6 connectionProps.put("user", "sa");

28 } catch (SQLException e) {
29 e.printStackTrace();
30 }
31 }

40 @Test
41 void testInitBaseDonnee() {

QUESTION
Hibernate Interceptor not working after upgrading to Hibernate 5
Asked 2021-Dec-28 at 05:27Earlier my Interceptor code was working fine for Hibernate 3. After I upgraded to Hibernate 5 and made the necessary changes, callback methods like onSave & onFlushDirty stopped working.
Regarding library changes, below Hibernate 3 jars I replaced with Hibernate 5 jars.
Hibernate 3 jars replaced-
- dom4j.jar
- hibernate-core-4.3.5.Final.jar
- hibernate-jpa-2.1-api-1.0.0.Final.jar
- jboss-logging.jar
Hibernate 5 jars added-
- byte-buddy-1.9.5.jar
- classmate-1.3.4.jar
- dom4j-2.1.1.jar
- hibernate-commons-annotations-5.1.0.Final.jar
- hibernate-core-5.4.1.Final.jar
- javax.persistence-api-2.2.jar
- javax.transaction.jar
- jboss-logging-3.3.2.Final.jar
Below is my Interceptor code-
1public class CustomInterceptor extends EmptyInterceptor {
2
3@Override
4public boolean onFlushDirty(Object entity, Serializable id, Object[] currentState, Object[] previousState, String[] propertyNames, Type[] types) {
5 System.out.println("onFlushDirty called");
6 return super.onFlushDirty(entity, id, currentState, previousState, propertyNames, types);
7}
8
9@Override
10public boolean onSave(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {
11 System.out.println("onSavecalled");
12 return super.onSave(entity, id, state, propertyNames, types);
13}
14}
15If someone can point out what I am missing or any correction that I need to make, it would be very helpful.
Please Note- Entire Application is working smoothly except that Interceptor Callback methods are not getting called.

Asked 2021-Dec-26 at 11:20In my Spring boot application I have the dependency for sqlite jdbc driver specified:
1<dependency>
2 <groupId>org.xerial</groupId>
3 <artifactId>sqlite-jdbc</artifactId>
4 <version>3.34.0</version>
5</dependency>
6and in pom.xml properties
1<dependency>

QUESTION
Log4j2 deadlock
Asked 2021-Dec-23 at 16:03My application is a sprint boot application that uses log4j2 and runs in a Wildfly server. After the zero day attak, we upgraded to the latest log4j2 version(2.16). But after the log4j upgrade, my application stops working once in a while. And when I looked at the threaddumps, I found that there is a deadlock created by log4j. Here is my log4j configuration. It was working fine before the upgrade.

77When analysing this issue, I came through a possible defect in log4j code. Not sure if that can result in a deadlock.
Log4J possible bug - As per the release notes, there was a fix to Enable immediate flush on RollingFileAppender when buffered i/o is not enabled. (LOG4J2-3114). But the code just does the opposite in RollingFileAppenderBuilder.

80 org.apache.logging.log4j.core.Layout<?> fileLayout = null;
81 if (bufferedIo) {
82 immediateFlush = true;
83 }
84...
85It should have been if(!bufferedIo) { immediateFlush = true; }. And one of my appender explicitly sets bufferedIo value to true. I know that log4j does a bufferedio by default and it is not necessary to set this flag explicitly. But unfortunately the code that I am working on is a legacy code and the configuration was working fine before the upgrade.

ANSWER
Answered 2021-Dec-23 at 16:03Found my answer in this thread https://developer.jboss.org/thread/241453. It is a log4j/jboss configuration issue. The fix is to either exclude jboss logging subsystem from jboss deployment configuration or get rid of the console appender. Thanks to Ralph Goers from Log4J team for guiding me towards the jboss thread.
I have closed the issue that I raised to https://issues.apache.org/jira/browse/LOG4J2-3274. The code snippet that I shared in this question was from log4j-1.2 compatibility adapter which doesn't has any impact in my code because I am already using the latest api version.
QUESTION
Invalid DateTimeFormat when inserting date in H2 in memory DB
Asked 2021-Dec-21 at 23:29I'm having a problem trying to insert values in a in-memory H2 DB.
I have this Entity:
1@Entity
2@Table(name="myTable")
3public class MyEntity {
4
5 @Id
6 @GeneratedValue(strategy = GenerationType.AUTO)
7 private long id;
8
9 @Column(name = "startDate")
10 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
11 private Date startDate;
12
13 @Column(name = "endDate")
14 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
15 private Date endDate;
16}
17I've used the pattern yyy-MM-dd-HH.mm.ss because the dates are in format like 2021-06-14-00.00.00 or 2021-12-31-23.59.59.
The @DateTimeFormat imported is org.springframework.format.annotation.DateTimeFormat; and Date is java.util.Date.
To insert values in the DB I've this script:
1@Entity
2@Table(name="myTable")
3public class MyEntity {
4
5 @Id
6 @GeneratedValue(strategy = GenerationType.AUTO)
7 private long id;
8
9 @Column(name = "startDate")
10 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
11 private Date startDate;
12
13 @Column(name = "endDate")
14 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
15 private Date endDate;
16}
17INSERT INTO myTable (ID, START_DATE, END_DATE) VALUES
18(1, '2020-08-07-00.00.00', '2021-12-31-23.59.59'),
19(2, '2020-04-03-14.00.00', '2021-01-14-18.30.00'),
20(3, '2020-09-15-00.00.00', '2021-06-15-11.00.00'),
21(4, '2020-01-18-16.00.00', '2021-12-31-23.59.59');
22But it throw an error:
1@Entity
2@Table(name="myTable")
3public class MyEntity {
4
5 @Id
6 @GeneratedValue(strategy = GenerationType.AUTO)
7 private long id;
8
9 @Column(name = "startDate")

11 private Date startDate;
12
13 @Column(name = "endDate")
14 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
15 private Date endDate;
16}

29The text in the error which is not in english is something like "Unable to interpret constant "TIMESTAMP"".
Also I have tested a few things and, (this is important!) removing hours, minutes and seconds, the program works, so I assume is the pattern which is not correct.
This SQL script works:
1@Entity
2@Table(name="myTable")
3public class MyEntity {
4
5 @Id
6 @GeneratedValue(strategy = GenerationType.AUTO)
7 private long id;
8
9 @Column(name = "startDate")
10 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
11 private Date startDate;
12
13 @Column(name = "endDate")
14 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
15 private Date endDate;
16}

34I've checked a DateTimeFormat tester online and the current date with my pattern is 2021-12-21-17.44.32, but even creating the table using only that date it thrown the error.
More info about the table:
The table (and also the columns) is created using spring.jpa.hibernate.ddl-auto=update so I assume the column type is DATE (as the entity field).
So I'm trying to insert a String with format yyy-MM-dd-HH.mm.ss in a DATE column (if I'm not wrong).
So, what's the problem? Is not possible to insert this pattern as date from string in an H2 in memory DB?
Thanks in advance.
ANSWER
Answered 2021-Dec-21 at 23:03If you are just trying to insert a java.util.Date into a TIMESTAMP column you don't need @DateTimeFormat. You are not parsing anything, you part from the Date object, and JPA translates it into the proper SQL datatype.
Define the column this way:
1@Entity
2@Table(name="myTable")
3public class MyEntity {
4
5 @Id
6 @GeneratedValue(strategy = GenerationType.AUTO)
7 private long id;
8
9 @Column(name = "startDate")
10 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
11 private Date startDate;
12
13 @Column(name = "endDate")
14 @DateTimeFormat(pattern="yyy-MM-dd-HH.mm.ss")
15 private Date endDate;
16}
17INSERT INTO myTable (ID, START_DATE, END_DATE) VALUES
18(1, '2020-08-07-00.00.00', '2021-12-31-23.59.59'),
19(2, '2020-04-03-14.00.00', '2021-01-14-18.30.00'),
20(3, '2020-09-15-00.00.00', '2021-06-15-11.00.00'),
21(4, '2020-01-18-16.00.00', '2021-12-31-23.59.59');

32(3, '2020-09-15', '2021-06-15'),

34 @Column(name = "startDate")
35 @Temporal(value=TemporalType.DATE)
36 private Date startDate;

38And you should be good to go.
Update
If only DATE pattern works, and no TIMESTAMP patterns work, it means that the column has been defined with the wrong datatype. DATE and TIMESTAMP are two different H2 datatypes (and in all the other DDBBs but may be with different names)
