添加依赖项后，弹簧云侦探不会在日志中显示任何信息

Question

我已经在我的 Spring 引导项目中添加了侦探依赖项。尽管存在依赖项，但在日志中看不到跟踪信息。没有编译或运行时错误。

下面是控制器的代码：

@RestController
@RequestMapping("/api/v1/device/")
public class TestProjectController {
private Logger logger = 
LoggerFactory.getLogger(this.getClass());
@Autowired
private TestProjectService tpService;
@RequestMapping(value = "/boottest", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<? extends Object> acquireLDAP(@RequestBody TestProjRequestModel onboardRequest,
        @RequestHeader HttpHeaders headers) {
    String traceId = UUID.randomUUID().toString();
    logger.info("traceId=" + traceId + "request=/boottest msg=Request to Onboard requestBody=" + onboardRequest);
    JsonEntity entity = new JsonEntity();
    try {
        ResponseEntity<? extends Object> responseEntity = new ResponseEntity<String>("test", HttpStatus.OK);
        HttpHeaders respHeaders =  responseEntity.getHeaders();
        for (Map.Entry<String, List<String>> entry : respHeaders.entrySet()) {
            String headerName = entry.getKey();
            for (String headerValue : entry.getValue()) {
                logger.info("Header Name::  " + headerName);
                logger.info("Header Val::  " + headerValue);
            }
        }
        return responseEntity;

我看到的日志

   2019-01-08 12:22:01,400 INFO  (c.c.l.o.c.TestProjectController:52) | 

请建议可以做些什么来按预期查看日志？预期日志类似于

2016-06-05 17:12:45.404  INFO [my-service3-id,73b62c0f90d11e06,73b62c0f90d11e06,false]

您需要在日志配置中添加 MDC 变量，例如 %X{X-B3-TraceId：-}见 https://cloud.spring.io/spring-cloud-sleuth/single/spring-cloud-sleuth.html#_log_correlation
