問題

本身spring boot已經集成了Jackson的庫，我想自己在Controller中直接使用Spring預設的ObjectMapper，應該怎麼做？

RestController.java

public class RestController {
    private final ObjectMapper jacksonObjectMapper;

    @Autowired
    public RestController(ObjectMapper jacksonObjectMapper) {
        this.jacksonObjectMapper = jacksonObjectMapper;
    }
}

 

或

@Autowired
private ObjectMapper jacksonObjectMapper;

參考：
