This sounds like a ClassLoader conflict. I'd bet you have the javax.persistence api 1.x on the classpath somewhere, whereas Spring is trying to access ValidationMode
, which was only introduced in JPA 2.0.
Since you use Maven, do mvn dependency:tree
, find the artifact:
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0</version>
</dependency>
And remove it from your setup. (See Excluding Dependencies)
AFAIK there is no such general distribution for JPA 2, but you can use this Hibernate-specific version:
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
OK, since that doesn't work, you still seem to have some JPA-1 version in there somewhere.
In a test method, add this code:
System.out.println(EntityManager.class.getProtectionDomain()
.getCodeSource()
.getLocation());
See where that points you and get rid of that artifact.
Ahh, now I finally see the problem. Get rid of this:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jpa</artifactId>
<version>2.0.8</version>
</dependency>
and replace it with
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.2.5.RELEASE</version>
</dependency>
On a different note, you should set all test libraries (spring-test, easymock etc.) to
<scope>test</scope>
