logoninterceptor.java

一个很精简的struts2实例工程,对入门很有用

package com.jamesby.struts2;

import java.util.Map;

import com.jamesby.struts2.persist.User;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class LogonInterceptor extends AbstractInterceptor{
	@Override
	public String intercept(ActionInvocation ai) throws Exception {
		Map session = ai.getInvocationContext().getSession();
		User user = (User) session.get("user");
		if (null != user) {
			return ai.invoke();
		} else {
			return Action.LOGIN;
		}
	}
}
