一、本节要点
1.消息的加解密
微信加解密包 下载地址：http://qydev.weixin.qq.com/java.zip ，此包中封装好了AES加解密方法，直接调用方法即可。
其中，解密方法为：
//2.获取消息明文：对加密的请求消息进行解密获得明文
WXBizMsgCrypt wxcpt=new WXBizMsgCrypt(WeiXinParamesUtil.token,WeiXinParamesUtil.encodingAESKey,WeiXinParamesUtil.corpId);
result = wxcpt.DecryptMsg(msg_signature, timestamp, nonce, postData);
加密方法为:
//6.加密
WXBizMsgCrypt wxcpt=new WXBizMsgCrypt(WeiXinParamesUtil.token,WeiXinParamesUtil.encodingAESKey,WeiXinParamesUtil.corpId);
respMessage = wxcpt.EncryptMsg(respMessage, timestamp, msgType);
2.被动回复消息的流程
用户发送消息之后，微信服务器将消息传递给 第三方服务器，第三方服务器接收到消息后，再对消息做出相应的回复消息。
接收消息：需先从request请求对象的输入流中获取请求参数和已加密的请求消息，再对已加密的请求消息进行解密操作，即可获得明文。
然后就行对明文消息的业务处理了。
回复消息：封装好回复消息后，需先对回复消息进行加密，获得已已加密消息，然后再通过http请求调用被动回复消息的接口，来发送消息。
二、接收消息服务器配置
接受消息服务器配置好后，用户发送消息时，微信服务器会将消息转发到配置的接受消息服务器url上，即以POST方式转发到 CoreServlet 上。
三、接收消息实体类的封装(req)
参见官方文档的说明
3.1 消息基类——BaseMessage
package com.ray.pojo.message.req; /**
