spring jbpm整合出错 ？

[kingjava]

在看了多位高手的帖子后，
决定自己整合spring+jbpm
但出错了。


环境如下：

eclipse 3.2 +myeclipse 5.0 +hibernate3.0/3.2+jbpm3.1.4


junit 测试 出错 ，错误信息如下：



org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory0' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.hibernate.DuplicateMappingException: Duplicate collection role mapping org.jbpm.identity.Group.children

hibernate 3.0 /3.2 都用过，
都不行 ，

请高手指教！

[kingjava]

配置如下:

[kingjava]

我分析了一下 ,
错误信息为:
-------------------------------------------------
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory0' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.hibernate.DuplicateMappingException: Duplicate collection role mapping org.jbpm.identity.Group.children
org.hibernate.DuplicateMappingException: Duplicate collection role mapping org.jbpm.identity.Group.children
-------------------------------------------------

大概的意思是在初始化 bean(sessionFactory0)的时候出错,

错误信息由spring 抛出,但错误信息是hibernate的异常.
"sessionFactory0" 还是"sessionFactory" 应该问题不大,
毕竟只是一个引用名字而已,.


还有一个信息是,我在单独使用jbpm测试的时候,
是没有任何问题的.hibernate可以正确加载.


刚才我换了 jdk1.6,
结果还是相同的错误

[kingjava]

原来我的 jdk是 1.4的

[angelseyes]

applicationContext.xml 贴出来sessionFactory0 配置有问题

[angelseyes]

检查你的mapping文件org.jbpm.identity.Group.children的配置

[kingjava]

问题 ，解决了 ，
问题出在 ： <property name="mappingLocations">
<value>classpath*:/org/jbpm/**/*.hbm.xml</value>
</property>
我在 工程里面 了 编译好的类包 和源文件包，
所以系统就加载配置文件两次，就 报那个
Duplicate collection role mapping
的错误 ，
把 重复的包去掉，问题解决 。

谢谢楼上的。
