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 from dual" />
        <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>
