一、微信消息分组群发接口简介
1、请求：该请求是使用post提交地址为：
https://api.weixin.qq.com/cgi-bin/message/mass/sendall?access_token=ACCESS_TOKEN
其中ACCESS_TOKEN是我们动态获取的。
发送的数据：(这里使用图文消息示例)
{
"filter":{
"group_id":"2"
},
"mpnews":{
"media_id":"123dsdajkasd231jhksad"
},
"msgtype":"mpnews"
}
filter，用于设定图文消息的接收者；
group_id，群发到的分组的group_id（可在java微信接口之二—获取用户组）；
mpnews,用于设定即将发送的图文消息；
media_id, 用于群发的消息的media_id(可在java微信接口之四—上传素材中获取)； msgtype,群发的消息类型，图文消息为mpnews，文本消息为text，语音为voice，音乐为music，图片为image，视频为video.
2、响应：该响应也是以json方式返回的
正确的时候返回的数据：
{
"errcode":0,
"errmsg":"send job submission success",
"msg_id":34182
}
errcode 错误码
errmsg 错误信息
msg_id 消息ID
错误的时候返回的数据：{"errcode":40004,"errmsg":"invalid media type"}
errcode，为错误代码，errmsg为错误信息
具体api可查看：http://mp.weixin.qq.com/wiki/index.php?title=%E9%AB%98%E7%BA%A7%E7%BE%A4%E5%8F%91%E6%8E%A5%E5%8F%A3
二、关于java代码的调用
该接口的调用与java微信接口四—上传素材一样，需要使用到commons-httpclient。其中数据是构造成json数据后，放在post方法请求体里面发送给服务器端。

发成功后会打印消息，但由于微信服务器的原因，消息不会立即发送，会过一段时间发送。
