动态调整日志级别

配置springboot-actuator

在pom文件中引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

在配置文件中开启loggers的endPoint端点

management:
  endpoints:
    web:
      exposure:
        include: loggers

查询日志级别

查看当前应用所有日志级别

curl http://localhost:8080/actuator/loggers

查看指定包/类日志级别

curl http://localhost:8080/actuator/loggers/ROOT

调整日志级别

curl -X POST -H "Content-Type: application/vnd.spring-boot.actuator.v2+json;charset=UTF-8"  -d '{"configuredLevel":"DEBUG"}' http://localhost:8080/actuator/loggers/ROOT
