应该是少jpa的包吧。

全部去除，换上spring2.5.6的包（dist/spring.jar）后就运行正常，一点错误没有---------------------------求解啊

我把注解换成XML的方式则运行正常，试用注解还是那个错误，能不能贴一下你用到的jar包，谢谢
2.5.8 Early support for Java EE 6
We provide support for asynchronous method invocations through the use of the new @Async annotation (or EJB 3.1's @Asynchronous annotation).
JSR 303, JSF 2.0, JPA 2.0, etc
----------可能JavaEE6还不是很好的兼容吧谢谢各位
