可以直接访问Action但是通过Ajax点击按钮访问的时候就没有访问

这个是拦截器：

package com.essa.Interceptor;

import org.apache.log4j.Logger;

import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;

/**

  • @name MyInterceptor
  • @time 2015-06-20
  • @version 1.0.0

  • @author ZhangDongxu
    */
    public class essaBoundaryInterceptor implements Interceptor {
    private static Logger logger = Logger.getLogger(essaBoundaryInterceptor.class.getName());

    /**

    • 自定义拦截器执行的代码
    • 作用：拦截请求
    • */ private static final long serialVersionUID = 1L;

    public void destroy() {}
    public void init() {}
    public String intercept(ActionInvocation invocation) throws Exception {
    logger.info(">>>>>> [请求信息：执行了自定义拦截器的代码！！！！]");
    return invocation.invoke();
    }

}

非常感谢
