### 注意 项目中使用druid 数据连接池的话 得以下加上配置，否则监控面板查看配置属性时，监控的对应项目会down掉，原因不明待研究 ###

# 开启连接池回收
    remove-abandoned: true
    # 超时连接回收时间，单位秒
    remove-abandoned-timeout: 30

### 注意 2.4.0版本会报错 （强迫中断一个远程连接主机 ），所以降低到 2.3.1 版本 原因不明待研究 ###

springboot 版本 2.4.4  
spring-boot-admin-starter-server 2.4.0  
spring-boot-admin-starter-client 2.4.0

### 注意配置查看日志时 ###
