详解spring cloud分布式日志链路跟踪

logging:
 path: D:\work\logs\project-solr #打印存放日志的路径
 level:
  com.gaofei: info #包名下日志的级别

logging:
 path: D:\work\logs\project-shopping-mall #打印存放日志的路径
 level:
  com.gaofei: info #包下面日志级别

@RestController//这里使此Constroller中所有的方法返回的不是页面
public class SolrSearchConstroller {

  public static Logger logger=LoggerFactory.getLogger(SolrSearchConstroller.class);

  @RequestMapping("/SolrSearch")
  public String SolrSearch(){
    logger.info("Solr被调用");
    return "这里是Solr";
  }

}

@Controller
public class PageController {

  public static Logger logger=LoggerFactory.getLogger(PageController.class);

  @Autowired
  private RestTemplate restTemplate;

  @RequestMapping("/toIndex")
  public String toIndex(Model model){

    logger.info("执行调用");
    String msg=restTemplate.getForEntity("http://project-solr/SolrSearch",String.class).getBody();//project-solr是调用注册中心里的名字
    logger.info("调用结束");
    model.addAttribute("msg",msg);
    return "/index";
  }
}
