http://topic.csdn.net/u/20090721/20/761beda6-ea58-4851-a174-72e608478420.html上面是出的异常，页面出的异常请看上面的地址，，谢谢

解决方案 »

  1.   

    com.wind.service.impl.UserServiceImpl
    没有继承
    com.wind.service.IUserService？
      

  2.   

    com.wind.service.impl.UserServiceImpl 
    和
    com.wind.service.IUserService的代码是什么样的？你看一下你在代码里写
    com.wind.service.IUserService us = new com.wind.service.impl.UserServiceImpl();
    会不会报错. 
      

  3.   

    saveUserAction中的属性userService不能将com.wind.service.impl.UserServiceImpl转型为com.wind.service.IUserService。
    你仔细看下这几个类的属性和在Spring中的配置文件吧。Bean没有成功建立，建议先在后台做测试。
