struts2 頁面跳轉控制傳參問題

以前網站作的基本差不錯了，客戶有其餘的活動需求，考慮能夠用struts2的攔截器實現

攔截器代碼：

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("攔截器初始化完畢");
	}

	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(不符合邏輯){
 //提示頁面
			return "no_role_taian";
		}
  //執行action
		return invocation.invoke();
	}

}

applicationContext.xml文件中引入攔截器配置文件

<import resource="interceptorContext.xml"/>

interceptorContext.xml文件內容：

<!-- 活動Struts攔截器struts過濾器測試 -->
<bean id="taiAnCBCSecTempInterceptor" class="org.main.manage.interceptor.temp.TaiAnCBCSecTempInterceptor">
 調用service注入配置
	<property name="orderService" ref="orderService"></property>
	<property name="secondService" ref="secondService"></property>
</bean>

在second.xml配置文件中設置攔截器棧：

<?xml version="1.0" encoding="UTF-8" ?>
