之前网站做的基本差不错了，客户有其他的活动需求，考虑可以用struts2的拦截器实现

拦截器代码：

package org.main.manage.interceptor.temp;import java.util.Map;import javax.servlet.http.HttpServletRequest;import org.apache.struts2.ServletActionContext;import org.main.common.util.PropertyUtil;import org.main.manage.dict.OrderDict;import org.main.manage.entity.TSecond;import org.main.manage.entity.TUser;import org.main.manage.service.OrderService;import org.main.manage.service.SecondService;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionInvocation;import com.opensymphony.xwork2.interceptor.Interceptor;public class TaiAnCBCSecTempInterceptor implements Interceptor {	private static final long serialVersionUID = -2578561479301489061L;	private SecondService secondService;	private OrderService orderService;	public OrderService getOrderService() {		return orderService;	}	public void setOrderService(OrderService orderService) {		this.orderService = orderService;	}	public SecondService getSecondService() {		return secondService;	}	public void setSecondService(SecondService secondService) {		this.secondService = secondService;	}	public void destroy() {	}	public void init() {		System.out.println("拦截器初始化完毕");	}	public String intercept(ActionInvocation invocation) throws Exception {		ActionContext ctx = invocation.getInvocationContext();    		Map session = ctx.getSession();		TUser user = (TUser)session.get("user");		if(null == user){			return "login";		}				HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);		String secNo = request.getParameter("secNo");		if(不符合逻辑){			//提示页面			return "no_role_taian";		} 		//执行action		return invocation.invoke();	}}

applicationContext.xml文件中引入拦截器配置文件

interceptorContext.xml文件内容：

   
   
    	调用service注入配置	
    	
    
   

       
   	
    		
     			
      							
      				
       				
       				
       				
       			
      		
     		
     		
     			
      			
      
       /no_role.jsp
      			
      
       /no_role_taian.jsp
      			//${secNo}接受后台传过来的值			
      
       /login_user.action?url=show_second.action?secNo=${secNo}
