I posted something similar of the same issue a few days ago but now I think I (with the help of some of the people who commented on the post) narrowed it down to know what I need help with exactly. I am trying to use the Spring Data JDBC in my application with the HSQLDB (am not trying to use a web server). But the driver doesn't support the get/set timeout for connections. Because of that, I cannot even use the database.
Here is the pom.xml:

I have a class that executes methods and there was such a problem that when changing the profile, I realized that hsqldb is not able to work with Java 8 Time API, so I want to use Profile to share execution with Postgres, I would like to know how this can be do This is class with methods
...ANSWER
Answered 2022-Mar-07 at 15:08change your application.properties per https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html and add postgresql to your maven/gradle dependencies.
or simply change from hsqldb to h2. Note that h2 supports OffsetDateTime but not ZonedDateTime at least in jdbc, I don't know all the conversions Spring would do if you tried to save a record with ZonedDateTime to a Timestamp column.

ANSWER
Answered 2022-Feb-27 at 18:25Luis Miguel Mejía Suárez's comment worked perfectly and was the easier approach.
In the context of this project, all I had to do was:
- Append
-SNAPSHOT
to the version in/version.sbt
(should not be needed normally but for this project I had to do this) - Run
sbt publishLocal
in the parent project.
After this, the example project (which already targets the -SNAPSHOT
version) is able to pick up the locally built package.
QUESTION
I am runnng Apache TomEE 9.0.0-M7 with Jakarta EE 9.1 Web Profile. When I run the application using a JTA datasource configuration, the code runs, however when I change to a RESOURCE_LOCAL configuration, the code fails with the exception below. The SQL in the query runs on the JTA configuration.
Please assist.
...ANSWER
Answered 2022-Feb-17 at 18:53By default you are running on an EE container, so it is using a JTA datasource.
If you really want to use RESOURCE_LOCAL, you should check this link on the TomEE documentation, i.e. you define a non-jta datasource in the container (via resources.xml or tomee.xml) and reference it via in the persistente.xml
You can find some information regarding the configuration of a datasource on the TomEE website.

This worked fine for me be building under Java 8. Now under Java 17.01 I get this when I do mvn deploy.

Any ideas?

This is actually a known bug, which is now open for quite a while: OSSRH-66257. There are two known workarounds:

QUESTION
I set the following pom.xml to use Camel 3.14.0:
...ANSWER
Answered 2022-Jan-11 at 12:04First and foremost its good to understand that Apache Camel is integration framework, Spring is application framework with probably its most notable feature being dependency injection. Due to this the documentation kinda expects the developer to be familiar with spring-framework and able juggle between camel and spring documentation.
Camel mainCamel-main in the other hand is tool you can use to run camel applications without any framework so it has no knowledge about spring framework. There's camel-spring-main but more on that later.
Spring-bootWhen it comes to spring it might be easier to just use spring-boot which you can think of as collection of maven dependencies you can use to auto-configure your spring application with default configurations.
I recommend that you create a new project using camel maven archetype camel-archetype-spring-boot. This should provide you with good starting point and example on how to get started with camel and spring.
To use spring-xml files with camel-spring-boot you can add annotation @ImportResource(classpath:META-INF/spring/camel-context.xml)
over your SpringBootApplication class (class annotated with @SpringBootApplication
, named MySpringBootApplication when using the template).
Change the path to match the location and name of your xml-file and delete or comment the example RouteBuilder class from the project to prevent it from interrupting with anything.
QUESTION
I'm developing a Spring Boot application and I'm having some trouble setting up RESTController tests. The problem is that, when I run the test classes individually, they all work. However, when I try to run all the test classes at once, only the first one works and the others throw java.lang.IllegalStateException: Failed to load ApplicationContext
. I have been debugging this and the problematic line is the following:
INSERT INTO users(username,password, email) VALUES ('admin','$2a$10$bicbzJTFskk8.sHWJauxCu2RzDIqXk/zCxQDZ5ByLQw0m0lQ6l2Pa', 'admin@mail.com') [23505-200] Caused by: org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:spring-boot/target/classes/db/hsqldb/data.sql]: INSERT INTO users(username,password, email) VALUES ('admin','$2a$10$bicbzJTFskk8.sHWJauxCu2RzDIqXk/zCxQDZ5ByLQw0m0lQ6l2Pa', 'admin@mail.com'); nested exception is org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Unique index or primary key violation: "PUBLIC.PRIMARY_KEY_4D ON PUBLIC.USERS(USERNAME) VALUES 1"; SQL statement:
This leads me to think that the data.sql
script is being executed on every test (which I believe should not be the case since my controller tests shouldn't rely on DB data). On top of that, the data is not being flushed after executing each class, so the first one works fine and the rest throw a @Unique
exception because the data is already there.
My REST controller tests look like this:

Answered 2022-Jan-17 at 11:01I feel like there are two different questions in this one.
First your problem is, that your entire SpringBootApplication is started because you are using @SpringBootTest
use @WebMvcTest
instead. You also "need" to use

I'm running macOS 11.6,LibreOffice 7.2.2.2,HSQLDB (my understanding is this is v.1.8, but don't know how to verify)
I'm a newbie to SQL, and I'm trying to write a DB to maintain a club membership roster. I'm trying to find everyone in the DB to whom renewal letters should be sent.
