Object转Map和Map转Object

举例：

FindArchiveDto findArchiveDto = new FindArchiveDto();
findArchiveDto.setContractStatus("降龙");
findArchiveDto.setCustName("明华");
findArchiveDto.setDepartmentName("赵无极");

fastjson转换方法：

//Object转Map
Map map = JSONObject.parseObject(JSONObject.toJSONString(findArchiveDto), Map.class);
Map<String,Object> map = JSONObject.parseObject(JSON.toJSONString(findArchiveDto));
//Map转Object
FindArchiveDto findArchiveDto1 = JSON.parseObject(JSON.toJSONString(map), FindArchiveDto.class);
FindArchiveDto findArchiveDto2 = JSONObject.toJavaObject(JSON.toJSONString(map), FindArchiveDto.class);

jackson的转换：

ObjectMapper mapper = new ObjectMapper();
//对象转map
Map m = mapper.readValue(mapper.writeValueAsString(findArchiveDto), Map.class);
//map转对象
FindArchiveDto dto = mapper.readValue(mapper.writeValueAsString(m), FindArchiveDto.class);
