strut2-spring整合中,拦截器interceptor注入服务或dao的方法

<interceptor name="moreAuthority" class="org.linyu.action.interceptor.MoreAuthorityInterceptor"> <param name="userDao"></param> </interceptor>

 

 private UserDao userDao; public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; }

 

如果 <param name="userDao">userDao</param>
填了userDao,那会报错.

com.opensymphony.xwork2.util.OgnlUtil.internalSetProperty(369) |

Caught OgnlException while setting property 'userDao' on type org.interceptor.MoreAuthorityInterceptor'.
 java.lang.NoSuchMethodException: setUserDao(java.lang.String)

 

实际代码中是有set方法的

 

不填写,则能自动注入
