How to Restore Spring Boot 2.1.x Request Mapping Logs with TRACE Level

Retrieve Request Path List from Logs

If you have followed earlier Spring Boot 1.x tutorials or are familiar with Spring MVC, the startup logs used to list all HTTP endpoints created by the application. These logs were produced by

org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping

scanning @Controller and @RequestMapping annotations.

Since Spring Boot 2.1.0 the log level for this information was changed from INFO to TRACE, so the endpoint list no longer appears by default. To restore it, add the following line to application.properties:

logging.level.org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping=trace

After restarting the application, TRACE logs will display each controller and its mappings, for example:

2020-02-11 15:36:09.787 TRACE 49215 --- [main] s.w.s.m.m.a.RequestMappingHandlerMapping :
    c.d.c.UserController:
    {PUT /users/{id}}: putUser(Long,User)
    {GET /users/{id}}: getUser(Long)
    {POST /users/}: postUser(User)
    {GET /users/}: getUserList()
    {DELETE /users/{id}}: deleteUser(Long)
    ...

The new output groups mappings by controller class, making it easier for developers to locate which HTTP endpoints have been initialized.
