struts2使用实例代码,通过这些实例

package com.briup.interceptor;

import java.util.Map;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class AuthorityInterceptor 
				extends AbstractInterceptor{

	@Override
	public String intercept(
			ActionInvocation invocation) throws Exception {
		ActionContext ac
		=invocation.getInvocationContext();
		//isLogin:true
		Map session=ac.getSession();
		Boolean isLogin
		=(Boolean) session.get("isLogin");
		//如果已经登陆,调用invocation的invoke方法
		if(isLogin!=null&&isLogin){
			return invocation.invoke();
		}
		//如果没有登陆,返回"login"
		else{
			return "login";
		}
		
	}
}
