hikari-cp
1.引入依赖
<!-- https://mvnrepository.com/artifact/com.zaxxer/HikariCP -->
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
<version>3.4.5</version>
</dependency>
2. spring配置
直接可用， maximumPoolSize 可以根据实际情况调整
<bean id="dataSource-hikari" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<!--<property name="driverClassName" value="com.mysql.cj.jdbc.Driver" /> mysql8 -->
<property name="url" value="${mysql.url}" />
<property name="username" value="${mysql.user}" />
<property name="password" value="${mysql.password}" />
<!-- maximumPoolSize 默认 10 -->
<property name="maximumPoolSize" value="20"/>
<!-- minimumIdle 默认 等于 maximumPoolSize -->
<!--<property name="minimumIdle" value="5"/>-->
<property name="connectionTestQuery" value="SELECT 1"/>
</bean>
3. springboot配置
minimum-idle 生产环境可以不设置，使用默认值即可
spring:
profiles: default
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
# mysql8 jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=Asia/Shanghai
# jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8
# mysql5 jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false
url: jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=Asia/Shanghai
username: root
password: 123456
# 默认
type: com.zaxxer.hikari.HikariDataSource
hikari:
# 不配置默认与maximum-pool-size相同
minimum-idle: 5
# 连接池最大连接数，默认是10
maximum-pool-size: 20
connection-test-query: SELECT 1
druid
1.引入maven依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.22</version>
</dependency>
2.spring配置
可以使用druid官方配置
<!-- 2. druid 数据库连接池 -->
<bean id="dataSource-druid" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${mysql.url}" />
<property name="username" value="${mysql.user}" />
<property name="password" value="${mysql.password}" />
<!-- 统计监控过滤器 -->
<property name="filters" value="stat" />
<!-- 连接池设置 -->
<property name="maxActive" value="20" />
<property name="initialSize" value="1" />
<property name="maxWait" value="60000" />
<property name="minIdle" value="1" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 1" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="poolPreparedStatements" value="true" />
<property name="maxOpenPreparedStatements" value="20" />
</bean>
dbcp2
1.引入依赖
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-dbcp2</artifactId>
<version>2.7.0</version>
</dependency>
2.spring配置
生产环境中 minIdle 和 initialSize 可以设置大些 8，根据实际情况设置。
maxTotal 参考druid的通用配置配置的数量
<bean id="dataSource-dbcp" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="${mysql.url}" />
<property name="username" value="${mysql.user}" />
<property name="password" value="${mysql.password}" />
<!-- 连接池设置 默认8-->
<property name="maxTotal" value="20" />
<property name="initialSize" value="1" />
<!-- 请求连接最大等待时间(毫秒)，默认-1（无限期） ，超出时间将抛出异常 -->
<property name="maxWaitMillis" value="60000" />
<!-- minIdle 默认 0-->
<property name="minIdle" value="1" />
<property name="validationQuery" value="SELECT 1" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
</bean>
