我在Mule中测试一个POC，包括Mule，就像bean spring一样，我遇到了Hibernate和Jpa依赖的问题。现在每个机构都支持/使用哪个版本的Hibernate和JPA在Mule 3.4 CE中。
当我不想运行流程时，我有很多异常：whith hibernate 3.6.0.Final：

我的春季服务在没有muleESB的测试环境中运行，没问题。
答案 0 :(得分：2)
Mule发行版在$ {MULE_HOME} / lib / opt中包含Hibernate核心JAR。但由于某种原因，它不包含Hibernate实体管理器JAR。因此，如果在类路径中包含hibernate-entitymanager.jar-4.0.1.Final，它将尝试从$ {MULE_HOME} / lib / opt JAR中访问核心hibernate类，这些JAR已由不同的类加载器加载，从而提供了java .lang.IllegalAccessError。
解决方案是从$ {MULE_HOME} / lib / opt中删除Mule提供的Hibernate JAR并添加您自己的。在进行此类操作之前，请确保备份。

答案 2 :(得分：0)
正如mmeyer所指出，这是一个类加载器问题。您可以在Mule 3.2中修复此问题.Mule提供了精细类加载选项。为了解决上述问题，我们可以在src / main / app / mule-deploy.properties中提供以下属性，并使用应用程序类加载器加载org.hibernate.engine.CascadeStyle和org.hibernate.engine.EJB3CascadeStyle：
loader.override = org.hibernate作为
注意：Mule Studio仍然继续这个问题，因此必须将hibernate实体管理器jar添加到\ MuleStudio \ plugins \ org.mule.tooling.server.3.4.1.ee_3.4.1.201312062152 \ mule \ opt < / p>
我使用mule CE独立观察：
My Mule App / lib - 有hibernate-entitymanager-3.6.0.Final。 - 我排除了所有其他的hibernate jar，包括hibernate-core-3.6.0.Final.jar
MuleCE3.4.0 / LIB /选择 - 有hibernate-core-3.6.0.Final.jar和其他hibernate jar
部署应用时出错： 引起：org.mule.api.config.ConfigurationException：在类路径资源[persistenceContext.xml]中定义名称为'entityManagerFactory'的bean创建错误：init方法的调用失败;嵌套异常是java.lang.IllegalAccessError：试图从类org.hibernate.engine.EJB3CascadeStyle $ 1（org.mule.api.lifecycle.InitialisationException）访问方法org.hibernate.engine.CascadeStyle。（）V
My Mule App / lib - 有hibernate-entitymanager-3.6.0.Final。 - 我排除了所有其他的hibernate jar，包括hibernate-core-3.6.0.Final.jar
MuleCE3.4.0 / LIB /选择 - 有hibernate-core-3.6.0.Final.jar和其他hibernate jar - [与场景1不同]将hibernate-entitymanager-3.6.0.Final复制到MuleCE / lib / opt
