关于在使用Hibernate时出现javassist.bytecode.DuplicateMemberException的问题

在某一entity类中增加几个属性后，启动jetty运行应用时，启动过程中出错并抛出异常。

其中一字段是“handler”

报错信息：

15:49:37,306 ERROR [BasicLazyInitializer] Javassist Enhancement failed: c.u.p.model.HandlerError: java.lang.RuntimeException: duplicate method: getHandler in c.u.p.model.HandlerError_$$_javassist_11        at javassist.util.proxy.ProxyFactory.createClass3(ProxyFactory.java:509) [javassist.jar:6.0.0.20100721-M4]        at javassist.util.proxy.ProxyFactory.createClass2(ProxyFactory.java:486) [javassist.jar:6.0.0.20100721-M4]        at javassist.util.proxy.ProxyFactory.createClass1(ProxyFactory.java:422)...Caused by: javassist.bytecode.DuplicateMemberException: duplicate method: getHandler in c.u.p.model.HandlerError_$$_javassist_11        at javassist.bytecode.ClassFile.testExistingMethod(ClassFile.java:637) [javassist.jar:6.0.0.20100721-M4]...15:49:37,311 WARN  [PojoEntityTuplizer] could not create proxy factory for:com.unifiedpost.payments.model.HandlerError: org.hibernate.HibernateException: Javassist Enhancement failed: c.u.p.model.HandlerError        at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.getProxyFactory(JavassistLazyInitializer.java:170) [:3.5.2-Final]        at org.hibernate.proxy.pojo.javassist.JavassistProxyFactory.postInstantiate(JavassistProxyFactory.java:66) [:3.5.2-Final]

hibernate的API解释

Description
