我想做什么？在加载我的项目时，我遇到了一个奇怪的异常：
rezg.admin.server.objects.common.pojo.EmailLogDetails，属性的setter方法：id
我将使用 postgres 将对象（持久化）保存到数据库中。环境是 Jboss 4 环境中的 Java 6、Hibernate 3。包含“EmailLogDetails”的 jar 位于 Jboss lib 文件夹中。
预期类型：java.lang.Integer，实际值：java.lang.Integer IllegalArgumentException 在类中：rezg.admin.server.objects.common.pojo.EmailLogDetails，属性的设置方法：id
org.hibernate.PropertyAccessException：在 org.hibernate 的 org.hibernate.property.BasicPropertyAccessor$BasicSetter.set(BasicPropertyAccessor.java:104) 调用 rezg.admin.server.objects.common.pojo.EmailLogDetails.Id 的设置器时发生 IllegalArgumentException .tuple.AbstractEntityTuplizer.setIdentifier(AbstractEntityTuplizer.java:204) 在 org.hibernate.persister.entity.AbstractEntityPersister.setIdentifier(AbstractEntityPersister.java:3261) 在 org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:157) ) 在 org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:114).....
原因：java.lang.IllegalArgumentException：对象不是在 sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) 在 sun.reflect.DelegatingMethodAccessorImpl 的 sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 声明类的实例.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.hibernate.property.BasicPropertyAccessor$BasicSetter.set(BasicPropertyAccessor.java:42) ... 还有 74 个
