Answer 2

应该Action在配置文件的配置问题了 ，仔细去检查一下

Answer 3

我的问题解决了，
把<aop:config>更改为<aop:config proxy-target-class="true"> ok！
希望你也能解决你的问题！！

问题已经摆出来了创建adminAction时在defined in file [D:\apache-tomcat-5.5.12\webapps\book\WEB-INF\classes\applicationContext-actions.xml]这个文件中初始化这个Bean活字段出现nested（嵌套式）Exception，除了这个错误之前还有错误，好好检查一下Applicationcontext.xml文件！看看虚拟路径是否一致！
