json用法以及必備的jar包

JSON的轉化。

String 轉成map

public static Map<String, Object> getTilteStyle(String recommendTitle){

JSONObject jsonObj=JSONObject.fromObject(recommendTitle);

Map<String, Object>  jsonMap=(Map<String, Object>)JSONObject.toBean(jsonObj, Map.class);

return jsonMap;

}

fastjson的轉化

public static Map<String, Object> getTilteStyle(String recommendTitle){

Map<String, Object> jsonMap=(Map<String, Object>)JSON.parseObject(jsonObj, Map.class);

return jsonMap;

}

jackson的map對象轉成json

 ObjectMapper objectMapper = new ObjectMapper();  
  String listJson = objectMapper.writeValueAsString(map);
