lizhanhui opened a new issue #1506: RocketMQ is producing non-standard-compliant JSON
URL: https://github.com/apache/rocketmq/issues/1506
 
 
   RocketMQ uses [fastjson](https://github.com/alibaba/fastjson) to serialize object to JSON text.
   Unfortunately, with the default configuration, the FastJson library does not respect the JSON standard as expected, which imposes an enormous obstacle for other languages to talk to RocketMQ.
   
   For example, 
   ```java
           Map<Integer, String> map = new HashMap<Integer, String>();
           map.put(1, "abc");
           map.put(2, "def");
           System.out.println(RemotingSerializable.toJson(map, false));
   ```
   generates
   ```text
   {1:"abc",2:"def"}
   ```
   which does not comply with the JSON standard and may be validated in [JSON Lint](https://jsonlint.com/).
   
   non-standard-compliant JSON can not be parsed by many JSON libraries, say JsonCpp, RapidJson, etc.  It's mandatory to fix this.
