登录后如何对密码时限进行校验并弹出修改密码框

	public static void systemProcessAfterLoginAction() {		
		List  users =  (List) ContextHelper.getActionContext().getActionResult();//获取action的返回结果
		Integer sPasswordTimeLimit = (Integer) users.get(8);//获取密码时限(天)
	    if(Utils.isNotNull(sPasswordTimeLimit) && sPasswordTimeLimit != -1){//判断密码时限不为空切不等于-1
	    	Date sPasswordModifyTime = (Date) users.get(9);//获取密码修改时间
	    	Date newDate = new Date();
	    	long nd = 1000 * 24 * 60 * 60;	    	
	    	long diff = newDate.getTime() - sPasswordModifyTime.getTime();// 获得当前时间和密码修改时间两个时间的毫秒时间差异	    	
	    	long day = diff / nd;// 计算差多少天
	    	if(day>sPasswordTimeLimit){//相差天数大于密码时限天数给session赋值
	    		HttpSession session = ContextHelper.getSessionContext().getSession();
	    		session.setAttribute("needModifyPassword", true);
	    	}    	
	    }

	}

需要注意在BIZ层的构建路径中把apache-tomcat\lib\servlet-api.jar导入，在java中引用
import javax.servlet.http.HttpSession;

2.把存储到session中的信息放到Context中，便于前端登录后获取判断
参考如何将自己需要的信息写到Context上下文中
如下：

	public static Object getSysParams() {
		 Map hashMap = (HashMap<String, String>) ContextHelper.getSysParams(); //平台默认的context中的信息
		 HttpSession session = ContextHelper.getSessionContext().getSession();
		 hashMap.put("needModifyPassword", session.getAttribute("needModifyPassword"));//把自己要的信息put到map中
		 return hashMap;
	}

3.通过扩展空间修改/UI2/portal/base/base.js
(1).添加引用

var WindowDialog = require("$UI/system/components/justep/windowDialog/windowDialog");

(2).在Model.prototype.loginDialogReceive = function(event) {函数中获取context中的信息判断打开修改密码的弹出框

	Model.prototype.loginDialogReceive = function(event) {
		this.beforeLogin();
		this.setPortalContext(event.data);
		this.afterLogin();		
		var needModifyPassword = this.getContext().getSystemParameter("needModifyPassword");
		if(needModifyPassword){
			if (confirm("您的密码已经过期，请按确定健进入密码修改窗。"))
				var changePasswordDialog = new WindowDialog({
					src : "$UI/portal/base/login/changePassword.w",
					parentNode : root,
					process : "/portal/process/message/messageProcess",
					activity : "mainActivity",
					title : '修改密码',
					showTitle : false,
					status : 'normal',
				});
				changePasswordDialog.open();
		}
	};

$UI/portal/base/login/changePassword.w的定义是直接复制的/UI2/portal/base/changePassword下的changePassword.w和对应的js文件
对/UI2/portal_X/base/login/changePassword.js文件中的修改
(1).添加引用

var MsgDialog = require("$UI/system/components/justep/messageDialog/messageDialog");

(2).代码修改

var result = this.changePassword(newValue, oldValue);
if(result.flag === false)
    justep.Util.hint(result.message, {type: 'danger', parent: this.getRootNode()});
else
    justep.Util.hint("密码修改成功！", {type: 'success', parent: this.getRootNode()});

修改为：

var result = this.changePassword(newValue, oldValue);
if (result.flag === false)
    justep.Util.hint(result.message, {
        type : 'danger',
        parent : this.getRootNode()
    });
else {
    var me = this;
    this.msg = new MsgDialog({
        parentNode : me.getRootNode(),
        type : 'OK',
        message : "密码修改成功，后续请使用新密码登录！",
        title:'修改密码提示'
    });
    this.msg.on('onOK', function(event) {
        me.close();
    }, me);
    this.msg.show();
}
