1 基本配置

pom.xml配置druid依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.21</version>
</dependency>

application.properties配置数据库连接信息

以spring.datasource.druid作为前缀

spring.datasource.druid.url=jdbc:mysql://localhost:3306/test
spring.datasource.druid.username=root
spring.datasource.druid.password=
spring.datasource.druid.driver-class-name=com.mysql.cj.jdbc.Driver

配置druid连接池

具体的信息可以自己查询相关的内容。

spring.datasource.druid.initialSize=10
spring.datasource.druid.maxActive=20
spring.datasource.druid.maxWait=60000
spring.datasource.druid.minIdle=1
spring.datasource.druid.timeBetweenEvictionRunsMillis=60000
spring.datasource.druid.minEvictableIdleTimeMillis=300000
spring.datasource.druid.testWhileIdle=true
spring.datasource.druid.testOnBorrow=true
spring.datasource.druid.testOnReturn=false
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxOpenPreparedStatements=20
spring.datasource.druid.validationQuery=SELECT 1
spring.datasource.druid.validation-query-timeout=500
spring.datasource.druid.filters=stat

配置druid监控

• 在pom.xml中增加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

• 在application.properties中添加druid监控配置

spring.datasource.druid.stat-view-servlet.enabled=true
spring.datasource.druid.stat-view-servlet.url-pattern=/druid/*
spring.datasource.druid.stat-view-servlet.reset-enable=true
spring.datasource.druid.stat-view-servlet.login-username=admin
spring.datasource.druid.stat-view-servlet.login-password=admin
