As soon as I upgrade to Hibernate 5.2.3 or above, Gradle isn't able to find my Entity Classes anymore:
Caused by: java.lang.IllegalArgumentException: Unknown entity: data.model.User
at org.hibernate.internal.SessionImpl.firePersist(SessionImpl.java:768)
at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:744)
at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:749)
at core.data.model.service.PersistenceService.lambda$create$0(PersistenceService.java:105)
at core.data.model.service.PersistenceService.withTransaction(PersistenceService.java:156)
It doesn't happen with Hibernate 5.2.2 and below.
This didn't fix it: what is gradle missing to map hibernate? .
This is my User class:
@Entity
@XmlRootElement
@Table(name = "user")
public class User extends EntityBase {
// some attributes
}
and my EntityBase class:
@XmlRootElement
@XmlAccessorType(value = XmlAccessType.NONE)
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
public abstract class EntityBase {
/**
* The entity's UUID.
*/
@Id
@XmlAttribute
private String uuid;
public EntityBase() {
uuid = UUID.randomUUID().toString();
}
}
The tests have their own persistence.xml, it looks like this:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="PersistenceUnit">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>data.model.User</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
<property name="hibernate.connection.url" value="jdbc:h2:mem:exerciseHandlerTest;DB_CLOSE_DELAY=-1"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
<property name="hibernate.transaction.jta.platform"
value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
<property name="hibernate.show_sql" value="false"/>
<property name="hibernate.format_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
I also get this Exception when running the tests:
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Difficulty is not mapped [select count(difficulty)
from Difficulty difficulty]
It is weird since this is happening only when running through Gradle, without it everything is fine .
Update 1
Apparently the problem isn't related to Gradle at all, because I just realized I am getting these Exceptions when running my Tests in IntellIJ:
java.lang.ExceptionInInitializerError
at core.test.BaseTest.<init>(NablaTest.java:55)
Caused by: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
...
Caused by: org.hibernate.engine.jndi.JndiException: Error parsing JNDI name [java:comp/env/jdbc/foobar]
... 37 more
Caused by: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
... 47 more
This makes me realize the Problem is that Since Hibernate 5.2.3 using a second persistence.xml, just for the Unit Tests isn't working
So I have a src/main/resources/META-INF/persistence.xml and a src/test/resources/META-INF/persistence.xml, but it keeps reading the persistence.xml from src/main/... starting with version 5.2.3 :(
Update 2
Okay, I know how to reproduce the problem, I just don't know why it's happening or how to fix it.
I have a multi-module-setup using the latest Gradle version. I have a core module with a build.gradle that contains the hibernate dependency:
compile "org.hibernate:hibernate-core:5.2.3.Final"
And then there's my module where the unit tests are failing:
dependencies {
// core functionalities
compile project(":core")
testCompile project(":core")
testCompile project(":core").sourceSets.test.output
}
If I comment out the last line ("testCompile project(":core").sourceSets.test.output") it's working fine.
Why is that?
try to upload to Hibernate 5.2.9.Final, using maven for example, and follow this persistence example:
@Entity
public class Customer {
@Id
private Integer id;
private String name;
@Basic( fetch = FetchType.LAZY )
private UUID accountsPayableXrefId;
@Lob
@Basic( fetch = FetchType.LAZY )
@LazyGroup( "lobs" )
private Blob image;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public UUID getAccountsPayableXrefId() {
return accountsPayableXrefId;
}
public void setAccountsPayableXrefId(UUID accountsPayableXrefId) {
this.accountsPayableXrefId = accountsPayableXrefId;
}
public Blob getImage() {
return image;
}
public void setImage(Blob image) {
this.image = image;
}
}
I faced the same type of situation, not the same error though. Test resources (class, conf files, etc...) should not be stored in the test part of core
but in a standalone project.
My solution :
core-test
project src/main
) the reusable code stored in the src/test
part of core
testCompile project(":core").sourceSets.test.output
by testCompile project(":core-test")
It should resolve your issue.
