请问各位:spring的事务代理是这样子用的吗??
报错:
Failed to convert property value of type [$Proxy3] to required type [my.dao.hibernate.UsersDAO] for property 'usersDAO'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy3] to required type [my.dao.hibernate.UsersDAO] for property 'usersDAO': no matching editors or conversion strategy found
[解决办法]
你的my.dao.hibernate.UsersDAO这个bean需要设置属性proxyTargetClass为true，这样产生的代理对象才会instanceof原来的类。
在事务中加上下面语句
<property name="proxyTargetClass" >
<value>true</value>
</property>
表面proxy代理的是类而不是接口。
