Ch18/hibernate-ogm code does not work

When I try to run the test class HibernateOGMTest I get for mongodb

javax.persistence.PersistenceException: Unable to build entity manager factory

main.HibernateOGMTest.setUp(HibernateOGMTest.java:26)

one of the warning says WARN: HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.

error out here entityManagerFactory = Persistence.createEntityManagerFactory("ch18.hibernate_ogm");

persistence.xml & pom.xml are exact match as the source code so no typo there.

But when I changed to using neo4j instead of mongodb there is no error anymore and the tests pass. can anyone confirm that the issue exists for them too?

Hello

According to the Korean translator's explanation, using the latest version of MongoDB, there was an error, and when using version 5.0, there was no error.

I also tried running it in a MongoDB 5.0.26 environment, and confirmed that the test code passes.

root@mongodb_docker_host:/# mongo --version
MongoDB shell version v5.0.26
Build Info: {
    "version": "5.0.26",
    ...

To resolve class access exceptions to modules not registered as unnamed modules, and file encoding warnings (my Windows Terminal Encoding: MS949), I also added the following to the pom.xml

Exception for class access to modules not registered as unnamed modules

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @20322d26

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>

  <configuration>

      <argLine>
          --add-opens java.base/java.lang=ALL-UNNAMED
      </argLine>
  </configuration>
</plugin>

The test didn't fail without the above JVM options added, but once they were added, the warning was no longer exposed.

File encoding warnings

[WARNING] File encoding has not been set, using platform encoding MS949, i.e. build is platform dependent!

  <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

Unless your Windows terminal encoding is multibyte, I don't think you need to set sourceEncoding to UTF-8.

Result: mvn clean test

have a nice day. 👍

I think the more specific cause is that the mongo-java-driver version used by hibernate-ogm-mongodb:4.2.0.Final is old.
