使用HikariCP數(shù)據(jù)源

pom.xml

<dependency>
  <groupId>com.zaxxer</groupId>
  <artifactId>HikariCP</artifactId>
  <version>3.3.1</version>
</dependency>

Spring-mvc.xml

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="shutdown">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="connectionTestQuery" value="SELECT 1" />
        <!-- 生效超時 -->
        <property name="validationTimeout" value="3000" />
        <!-- 連接只讀數(shù)據(jù)庫時配置為true， 保證安全 -->
        <property name="readOnly" value="false" />
        <!-- 等待連接池分配連接的大時長（毫秒），超過這個時長還沒可用的連接則發(fā)生SQLException， 缺省:30秒 -->
        <property name="connectionTimeout" value="60000" />
        <!-- 一個連接idle狀態(tài)的大時長（毫秒），超時則被釋放（retired），缺省:10分鐘 -->
        <property name="idleTimeout" value="60000" />
        <!-- 一個連接的生命時長（毫秒），超時而且沒被使用則被釋放（retired），缺省:30分鐘，建議設(shè)置比數(shù)據(jù)庫超時時長少30秒，參考MySQL
            wait_timeout參數(shù)（show variables like '%timeout%';） -->
        <property name="maxLifetime" value="60000" />
        <!-- 連接池中允許的大連接數(shù)。缺省值：10；推薦的公式：((core_count * 2) + effective_spindle_count) -->
        <property name="maximumPoolSize" value="10" />
    </bean>
