调用 public void send(String queue, String msgBody, SendCallback callback) throws MQClientException, MQServerException {
send(queue, msgBody, -1, callback);
}

定位报错：
Method threw 'java.lang.NoClassDefFoundError' exception. Cannot evaluate com.qcloud.cmq.client.protocol.Cmq$cmq_tcp_send_msg$Builder.toString()

你们两个测试样子类能加一下package吗

直接返回空就好了吧？ 为啥扔异常呢

CMQServerException继承RuntimeException，但是构造方法未给message付任何值，有问题堆栈里永远打印null

Method threw 'java.lang.NoClassDefFoundError' exception. Cannot evaluate com.qcloud.cmq.client.protocol.Cmq$cmq_tcp_send_msg$Builder.toString()

调用publishMessage时，当发的是以下数据，会报com.qcloud.cmq.Json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]的错误.

相关#5

虽然 #5 比较生效，但是连接没有关闭，修改requestMethod会发生标题中的异常

这个比较导致每次都是false
public String request(String method, String url, String req, int userTimeout) throws Exception { String result = ""; BufferedReader in = null; try { if (this.url != url) this.newHttpConnection(url);

请检查下这里是否丢掉了, conn.disconnect(); 将connection关闭, 如果你想复用连接，那么请不要使用in.close()将response 流关闭。

只有创建订阅的Subscripton，但是没有监听者啊，what ？

Message等类属性为public的。
CMQServerException类属性为private的，但没有get方法
Topic类又为protected
用规范 一扫描全是问题，能否按照规范整理一遍。
建议代码提交前，先用相关工具扫描一下是否有bug或漏洞。
另外，代码里面所有
JSONObject jsonObj = new JSONObject(result);
CMQTool.checkResult(result);
这两行代码应该互换一下，返回为null的时候 第一行就已经报空指针异常了。

小错误，希望修正一下。
