Hibernate symbols @id @column are not recognized

Question

In my User class, I'm trying to add the symbols @id and @column.

I'm getting a compile error:

cannot find symbol class id/column.

I'm using IDEA.

In the docs, I don't see any reference for @Id and @Column: http://docs.jboss.org/hibernate/stable/annotations/api/

I have this in my pom.xml:

Answer 1

Java is case sensitive. It's @Id and @Column. Also, those are JPA annotations, i.e. they're not part of Hibernate but of Java EE (in the javax.persistence package). The corresponding Hibernate annotations are @PrimaryKey and @Column from the org.hibernate.mapping package.

Answer 2

If you want to use the JPA 1.0 implementation, you need the following dependencies:

<properties>
  <org.hibernate.version>3.4.0.GA</org.hibernate.version>
</properties>
<repositories>
  <repository>
    <id>repository.jboss.org-public</id>
    <name>JBoss Public Repository Group</name>
    <url>https://repository.jboss.org/nexus/content/groups/public&lt;/url&gt;
  </repository>
</repositories>
<dependencies>
  <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>${org.hibernate.version}</version>
  </dependency>
  <!-- Hibernate uses slf4j for logging, we use log4j as backend -->
  <dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.14</version>
  </dependency>
</dependencies>

If you want to use the JPA 2.0 implementation, simply replace the org.hibernate.version by:

<properties>
  <org.hibernate.version>3.5.3-Final</org.hibernate.version>
</properties>

In both cases, the above Hibernate dependency will give you everything you need transitively.

As you may have noticed, Hibernate uses SLF4J while Spring uses Jakarta Commons Logging. I suggest to configure Spring to use SLF4J as well as explained in this previous answer.

Answer 3

What you need is java's persistence annotation You can either add dependency of

javax.persistence:persistence-api

Although adding dependency to hibernate entity manager will resolve you transitively, I would still recommend to add dependencies that you have really used in your artifact.
