SpringBoot动态修改日志级别

• 首先需要在项目中添加 actuator 依赖

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

• actuator 默认暴露的http端口只有 info 和 health，需要把 loggers 端点暴露出来

  management:
    endpoints:
      web:
        exposure:
          include: health, info, loggers

• 查看日志信息

  curl -X GET 'http://localhost:8080/actuator/loggers'

• 动态修改日志级别

  # url最后跟的是想要改变日志级别的包名
  curl -H "Content-Type:application/json" -X POST -d '{"configuredLevel":"DEBUG"}' 'localhost:8080/actuator/loggers/com.xxx.xxx'
