SpringBoot集成Druid實現監控

application.properties文件完整信息

#連接數據庫
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.datasource.url=jdbc:mariadb://localhost:3306/empDB
spring.datasource.username=oukele
spring.datasource.password=oukele

#連接池
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
#初始化 、最小、最大
spring.datasource.initialSize = 5
spring.datasource.minIdle = 1
spring.datasource.maxActive = 20
#設置獲取超時等待的時間
spring.datasource.maxWait = 60000
#配置一個連接在池中最小生存時間，單位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000

spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false

# 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
spring.datasource.filters=stat,wall,logback

 創一個 DruidConfig類
