Spring Boot 2.1 MVC日志记录

Question

Spring Boot2.0.x记录了MVC在信息级别的映射，这是非常方便和容易识别的日志。

**Spring Boot 2.0.x**
2019-01-24 20:10:11.165  INFO  [           main]  s.w.s.m.m.a.RequestMappingHandlerMapping  Mapped "{[/mapping2],methods=[GET]}" onto public java.lang.String com.test.controller.ControllerClass.method2()
2019-01-24 20:10:11.167  INFO  [           main]  s.w.s.m.m.a.RequestMappingHandlerMapping  Mapped "{[/mapping1],methods=[GET]}" onto public java.lang.String com.test.controller.ControllerClass.method1()

根据Spring Boot 2.1.x文档，https://github.com/spring-projects/spring-boot/wiki/spring-boot-2.1-release-notes#logging-refinements

没有MVC映射的信息日志。仅将摘要记录为调试日志。我们必须更新level to TRACE以获得更多详细信息。

Answer 1

从Spring Boot2.1版本获取控制台上的RequestMappingHandlerMapping日志，尝试添加

logging.level.org.springframework.web=trace

在application.properties文件上
