Question

从2.0.x升级Spring Boot 2.1.x，而不记录MVC映射日志。

Spring Boot 2.0.x 记录了INFO级别的MVC映射，这是非常方便且易于识别的日志。

**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

没有用于MVC映射的信息日志。仅摘要记录为调试日志。我们必须将级别更新为TRACE才能获取更多详细信息。

**Spring Boot 2.0.x**
2019-01-24 20:16:08.549 TRACE 2516 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : 
    c.t.c.ControllerClass:

    {GET /mapping2}: method2()
2019-01-24 20:16:08.554 TRACE 2516 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping :

    { /error, produces [text/html]}: errorHtml(HttpServletRequest,HttpServletResponse)
2019-01-24 20:16:08.560 DEBUG 2516 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : 4 mappings in 'requestMappingHandlerMapping'
2019-01-24 20:16:08.584 DEBUG 2516 --- [           main] o.s.w.s.h.BeanNameUrlHandlerMapping      : Detected 0 mappings in 'beanNameHandlerMapping'

通过将Web日志级别更新为DEBUG或TRACE，我们可以从Spring Web获得更多的调试日志，并且它们并不总是有用。除非是TRACE级别，否则它们意义不大。

2019-01-24 20:39:59.767 TRACE 2516 --- [nio-8080-exec-5] o.s.web.servlet.DispatcherServlet        : GET "/mapping1", parameters={}, headers={masked} in DispatcherServlet 'dispatcherServlet'

是否可以获取Spring日志信息？如何？

从Spring Boot 2.1版本获取控制台上的RequestMappingHandlerMapping日志，然后尝试添加

logging.level.org.springframework.web=trace

在application.properties文件上
