SpringBoot 打印 RequestMapping 信息配置

Spring Boot 2.1 之前的版本

Spring Boot 2.1 之前 使用INFO 級別記錄的信息很多，所以只需要配置爲INFO程序啓動的時候就可以打印 RequestMapping 的信息，示例如下：

logging:
  level:
    root: info

打印出來的格式如下：

Spring Boot 2.1 之後的版本

Spring Boot 2.1 以後 使用了 Spring Framework 5.1, 而 Spring Framework 5.1 對日誌做了較大的改動。現在使用 INFO 級別記錄的信息非常少，DEBUG 級別提供了更多信息，但不詳細。只有 TRACE 級別纔會提供詳細信息。這時候爲了要打印Controller裏面的 RequestMapping信息需要把org.springframework.web打印日誌的格式設置爲trace，示例如下：

logging:
  level:
    root: info
    org.mybatis: debug
    java.sql: debug
    org.springframework.web: trace

日誌輸出格式如下：把每個Controller下面的所有RequestMapping全部列到一個Controller下面，打印格式比之前的格式可讀性和區分性更好一些
