    		/WEB-INF/jsp/inc/error.jsp
    		/WEB-INF/jsp/login.jsp
    		/WEB-INF/jsp/inc/exception.jsp
    	
    	
    	
    		
    	
    	
    	
    		${url}
    	
		
		
		
		
			/WEB-INF/jsp/{1}/{2}.jsp
			/WEB-INF/jsp/{1}/{2}Input.jsp
			${url}
			
		
    

	

下面是拦截器的代码：

package org.test.ssh.filter;

import org.springframework.stereotype.Component;
import org.test.ssh.model.User;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;
/**
 * 用struts拦截器做权限控制，这个方法不常用，一边用filter就能控制好了。

@SuppressWarnings("serial")
@Component("authInterceptor")
public class AuthInterceptor extends AbstractInterceptor {

	@Override
	public String intercept(ActionInvocation invocation) throws Exception {
		String an = invocation.getProxy().getActionName();//获取Action的名字
		if (!an.startsWith("login")) {
			User loginUser = (User)ActionContext.getContext().getSession().get("loginUser");
			if (loginUser==null) {
				return "login";
			}
		}
		return invocation.invoke();
	}
