myObject2 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:

The @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:

Does hibernate set back reference in @OneToMany @ManyToOne relationship automatically?

ANSWER

Answered 2022-Feb-13 at 16:26

For 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 20:28

I'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?

This 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 14:13

I've just upgraded the version I use for Hibernate to 5.6.1 and it seems it's now deprecating some Type-related annotations:

...

ANSWER

Answered 2022-Jan-18 at 14:13

It 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.

ANSWER

Answered 2022-Jan-06 at 14:53

The 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:

My 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.

ANSWER

Answered 2021-Dec-23 at 16:03

Found 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.

If 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:
