【liferay】6、可配置式cookie

2022-10-04 08:22:09

问题提出

项目运行中，cookie的作用一般是起着一个不可或缺的权限控制或者认证的作用，但是如果是多系统交互，cookie是由别的系统生成，本系统对接的话，那么这个cookie就会

成为项目测试的一个麻烦

那么我们可以基于这个，开发一个cookie的配置页面

1、展示目前所有的cookie

2、对已有的cookie进行操作

3、可以新增对应的cookie

配置文件修改

首先在liferay-portlet.xml中添加一个

<requires-namespaced-parameters>false</requires-namespaced-parameters>

可以避免在页面传参的时候，要加namespace的尴尬

其余的配置文件，按照eclipse自带的生成方式生成就可以了

定义页面

定义init页面

init.jsp

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %>

<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme" %>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<portlet:defineObjects />

view.jsp

<%@ include file="/html/common/init.jsp" %>

<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8" deferredSyntaxAllowedAsLiteral="true"%>

<!-- 一般不跳转到其他页面的时候，doview 等 我们使用renderRequest渲染页面 -->

<portlet:renderURL var="cookieform"></portlet:renderURL>

<!-- 查询，修改，新增，删除 -->

<portlet:resourceURL id="cookieAjax" var="oper"></portlet:resourceURL>

<portlet:actionURL var="modCookie" name="modCookie">

    <portlet:param name="jspPage" value="/html/cookieoperator/view.jsp"/>

</portlet:actionURL>

<!-- 获取根目录 -->

<%

    String rootPath = renderRequest.getContextPath();

    String title = "配置cookie";

%>

<script type="text/javascript" src="<%=rootPath%>/js/jQuery/jquery-3.1.1.js"></script>

<link rel="stylesheet" type="text/css" href="<%=rootPath%>/css/cookieoperator/main.css" />

<!-- 展示所有的cookie -->
