Java微信二次开发(五)

消息加密

需要到入库:commons-io-2.4.jar,commons-codec-1.9.jar(在官网的Java微信加密demo下)

第一步:访问https://mp.weixin.qq.com/wiki,下载AES加密的示例代码

Java微信二次开发(五) 

 

第二步:新建com.wtz.aes包,把实例代码中的8个AES加密类复制进去,将这些类的包名改为com.wtz.aes,导入库commons-codec-1.9.jar,选上面的Project下的Properties,点击Java Build Path,Libraries,Add Library,选Junit 4,Next,Finish,OK,AES加密导入完成

 

第三步:找到包com.wtz.util,新建类Parameter.java类,存放参数token,encodingAESKey(随机戳),corpId(AppID),这些在基本配置处可以得到

 1 package com.wtz.util;

12     //随机戳
13     public static String encodingAESKey = "X78dYU3MXpijKArRbiozTRq0jZZnjxxvuB4n8KJwRH1";
14     //应用AppID
15     public static String corpId = "wx9621c31e147dfdf9";
16 }

 

第四步:找到包com.wtz.util下的MessageUtil.java类,修改parseXml方法
