LogBack 动态修改日志级别

LogBack 动态修改日志级别

由于线上运行的项目，出现问题 想看下sql的参数，或者一些框架的debug日志。需要把日志界别从info-->debug。需要动态实时的修改日志界别。

只要类： LoggersEndpoint 

maven 依赖:

        
            org.springframework.boot
            spring-boot-starter-actuator
        

springboot1.x

===================yml配置 ==========================================================

server:
  port: 8083
  context-path: /

endpoints:
  enabled: true
  
management:
  security:
    enabled: false
  
  
====================默认级别 INFO ==========================================================
    
  
logLevel: '{"com.xx.elk":"INFO","com.xxx.mapper":"INFO"}'
  
  
====================代码使用===========================================================
@Autowired
private LoggersEndpoint loggersEndpoint;
 
private static SortedMap logLevel;
 
@NacosValue(value = "#{${hjd.nacos.logLevel}}", autoRefreshed = true)
public void setLogLevel(SortedMap logLevel) {
    HjdApolloConfig.logLevel = logLevel;
 
    //加载配置参数时 对应未初始化 
    if (loggersEndpoint == null) {
        return;
    }
    logLevel.forEach((k, v) -> loggersEndpoint.setLogLevel(k, LogLevel.valueOf(v)));
}

 浏览器访问： http://localhost:8086/dyj/loggers  可以看到项目中所有的日志配置

=====================通过nacos/apollo动态修改参数===========================================
logLevel: '{"com.xx.elk":"DEBUG","com.xxx.mapper":"DEBUG"}'

 得到sql执行参数

springboot2.x的配置

management:
  endpoints:
    web:
      exposure:
        include: "*"
      base-path: /actuator
  
loggersEndpoint.configureLogLevel(xxx,xxxx);
