Spring Boot2.x 的Druid连接池配置[附带监控]

Posted 2022-04-02 lywj

父依赖【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>

 

主要依赖【3个】

<!--Druid 连接池与Spring Boot结合的依赖-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.10</version>
</dependency>
<!--Spring Boot Web 依赖，Druid中的某些组件还是有依赖Web组件的，毕竟监控是需要页面显示的-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--mysql 依赖【8.0+版本】，当然spring boot也可以连接其他关系型数据库，但是此代码不做其他示例-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

 

Spring Boot配置文件配置

#datasource base config
spring.datasource.username=数据库用户名
spring.datasource.password=数据库密码
spring.datasource.url=jdbc:mysql://数据库IP:端口/数据库名称?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

 

基本测试前提：

加上一些基本操作数据库操作的controller,
然后访问项目： http://ip:端口/druid
然后输入上面配置的用户和密码root即可访问

附2：本项目示范代码及代码示例

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

示例：http://lb-chen.cn:9005/druid 用户和密码都为root

如果监控台没有任何数据，请访问如下地址再刷新控制台即可
