struct2 拦截所有没有登录的用户，强行转到登录界面AuthorizationInterceptor-优快云博客

本文介绍了一个自定义的Struts2权限拦截器实现，该拦截器通过检查当前用户的会话来确定是否允许访问特定操作。此外，还展示了如何在struct.xml中配置此拦截器及其忽略的动作列表。

package com.sise.action;

import java.util.Map;

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

public class AuthorizationInterceptor extends AbstractInterceptor {
	private String ignoreActions;

	// ignoreActions属性的getter方法
	public String getIgnoreActios() {
		return ignoreActions;
	}
	// ignoreActions属性的setter方法
	public void setIgnoreActions(String ignoreActions) {
		this.ignoreActions = ignoreActions;
	}
	@Override
	public String intercept(ActionInvocation invocation) throws Exception {
		ActionContext ctx = invocation.getInvocationContext();
		Map session = ctx.getSession();
		Object user = session.get("currentUserId");
		boolean ignore = false;
		if (user != null || ignore == true) {
			return invocation.invoke();
		} else {
			return Action.LOGIN;
		}
	}
}
