Spring Boot2.x 的Druid鏈接池配置[附帶監控]

父依賴【Spring Boot 2.1.x版本】

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.1.RELEASE</version>
</parent>

 

主要依賴【3個】

<!--Druid 鏈接池與Spring Boot結合的依賴-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.10</version>
</dependency>
<!--Spring Boot Web 依賴，Druid中的某些組件仍是有依賴Web組件的，畢竟監控是須要頁面顯示的-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--mysql 依賴【8.0+版本】，固然spring boot也能夠鏈接其餘關係型數據庫，可是此代碼不作其餘示例-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

 

Spring Boot配置文件配置

#datasource base config
spring.datasource.username=數據庫用戶名
spring.datasource.password=數據庫密碼
spring.datasource.url=jdbc:mysql://數據庫IP:端口/數據庫名稱?useUnicode=true&useSSL=false
#annoated driverClassName,have [cj]
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#druid pool standard config
spring.datasource.druid.max-active=30
spring.datasource.druid.initial-size=3
spring.datasource.druid.min-idle=3
spring.datasource.druid.max-wait=12000
spring.datasource.druid.time-between-eviction-runs-millis=60000
spring.datasource.druid.min-evictable-idle-time-millis=30000
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-open-prepared-statements=30

spring.datasource.druid.validation-query=select 1 from dual
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false

#druid extends config
#druid sql firewall monitor
spring.datasource.druid.filter.wall.enabled=true

#druid sql monitor
spring.datasource.druid.filter.stat.enabled=true
spring.datasource.druid.filter.stat.log-slow-sql=true
spring.datasource.druid.filter.stat.slow-sql-millis=10000
spring.datasource.druid.filter.stat.merge-sql=true

#druid uri monitor
spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*

#druid session monitor
spring.datasource.druid.web-stat-filter.session-stat-enable=true
spring.datasource.druid.web-stat-filter.profile-enable=true

#druid spring monitor
spring.datasource.druid.aop-patterns=com.xcky.*

#druid login user config
spring.datasource.druid.stat-view-servlet.login-username=root
spring.datasource.druid.stat-view-servlet.login-password=root

 

基本測試前提：

加上一些基本操做數據庫操做的controller,
而後訪問項目： http://ip:端口/druid
而後輸入上面配置的用戶和密碼root便可訪問

附2：本項目示範代碼及代碼示例

示例源代碼：https://github.com/XiaoCao1434/shop-druid

示例：http://lb-chen.cn:9005/druid 用戶和密碼都爲root

若是監控臺沒有任何數據，請訪問以下地址再刷新控制檯便可
