我有纯粹而简单的Java Nio套接字服务器。使用JSON实现数据传输。 1 clien都工作正常,但当我尝试启动工作负载测试时 - 出现了一些问题。这是我解析传入的ByteBuffer的方法(MessageFromBuffer只是byte []的包装器):
private JSONObject parseIncomingMessageToJson(MessageFromBuffer messageFromBuffer) {
int size = messageFromBuffer.getSize();
byte[] data = messageFromBuffer.getData();
byte[] dataCopy = new byte[size];
System.arraycopy(data, 0, dataCopy, 0, size);
JSONParser jsonParser = new JSONParser();
JSONObject jsonMessage = null;
try {
jsonMessage = (JSONObject) jsonParser.parse(new String(dataCopy));
} catch (ParseException pe) {
System.out.println("Error formatting incoming message to json: " + new String(messageFromBuffer.getData()));
}
return jsonMessage;
}
当缓冲区仅包含一个json实体时 - 一切正常。但是在100个客户端攻击期间,缓冲区可以填充多个json enities,如图所示(所有测试客户端发送相同的数据):
Error formatting incoming message to json: {"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
{"TYPE":"REGISTRATION","LOGIN":"Padre","PASSWORD":"3214"}
方法抛出异常并返回任何内容。每次从SOcketChanel读取后我清除缓冲区 - 所以这些消息都丢失了。在这种情况下是否有一些适当的JSON解析技术?
答案 0 :(得分:2)
根据您发布的内容,它看起来类似于this,因为输出是使用下一行字符分隔的。您可以利用它将字符串拆分为序列化json响应数组。
然后你可以将它们分别解析为json对象。
