在3.4.0 CE中使用mule-module-jpa 1.2.0和Hibernate。如何定义EntityManager？

Question

有人能给我指出一个适用于Mule3.4CE的mule-module-jpa的工作示例吗？

我的maven deps确实包含了相关的Hibernate内容，并且在Studio下运行时，我确实看到了JAR包含在输出目录中。但是mule classloader似乎不能找到它们...或者我不知道需要什么。

我尝试了几种Hibernate和Spring-orm版本的组合，目前正在使用每种版本的最新版本：

<spring.version>4.0.0.RELEASE</spring.version>
<hibernate.version>4.2.2.Final</hibernate.version>

我的pom的相关部分看起来像：

Answer 1

想想看，mule已经包含了一些hibernate-core和Hibernate-JPA。错误可能是由冲突引起的。尝试验证未找到的类是否已经在这些JAR中。
