问题

本身spring boot已经集成了Jackson的库，我想自己在Controller中直接使用Spring默认的ObjectMapper，应该怎么做？

RestController.java

public class RestController {
    private final ObjectMapper jacksonObjectMapper;

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

或

@Autowired
private ObjectMapper jacksonObjectMapper;
