请告诉我。如何配置“Hikari 连接池 + Hibernate 4.3.8 + Spring Data JPA 配置”？这是我的配置，但出于某种原因，我确信此配置不正确。因为控制台没有出现“连接池”之类的东西。在互联网上我找不到初学者的教程。谢谢。

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    p:dataSource-ref="dataSource" p:packagesToScan="com.history"
    p:jpaVendorAdapter-ref="jpaVendorAdapter">
    <property name="jpaProperties" ref="hibernateProperties" />
</bean>

<bean id="jpaVendorAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">

    <property name="generateDdl" value="true" />
    <property name="database" value="ORACLE" />
    <property name="databasePlatform" value="org.hibernate.dialect.OracleDialect" />
</bean>

<util:map id="hibernateProperties">
    <entry key="hibernate.connection.driver_class"
        value="org.hibernate.hikaricp.internal.HikariCPConnectionProvider" />

如果你想使用 Hikari，你需要声明它，所以你的 dataSource 配置应该是

<bean id="dataSource"
    class="com.zaxxer.hikari.HikariDataSource">
    <property name="driverClassName" value="${dataSource.driverClassName}" />
    <property name="jdbcUrl" value="${dataSource.url}" />
    <property name="username" value="${dataSource.username}" />
    <property name="password" value="${dataSource.password}" />
</bean>

你的数据源配置应该是这样的：

 <beans:bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource"  destroy-method="close">
                <beans:property name="dataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"/>
                <beans:property name="maximumPoolSize" value="5" />
                <beans:property name="maxLifetime" value="30000" />
                <beans:property name="idleTimeout" value="30000" />
                <beans:property name="dataSourceProperties">
                          <beans:props>
                              <beans:prop key="url">jdbc:mysql://localhost:3306/exampledb</beans:prop>
                              <beans:prop key="user">root</beans:prop>
                              <beans:prop key="password"></beans:prop>
                               <beans:prop key="prepStmtCacheSize">250</beans:prop>
                               <beans:prop key="prepStmtCacheSqlLimit">2048</beans:prop>
                               <beans:prop key="cachePrepStmts">true</beans:prop>
                               <beans:prop key="useServerPrepStmts">true</beans:prop>
                          </beans:props>
                </beans:property>
</beans:bean>

我们也可以像下面这样在自定义 JPAConfiguration 类中使用它，您可以在其中建立连接并创建实体 Manager Factory 对象。

         import com.zaxxer.hikari.HikariConfig;
         import com.zaxxer.hikari.HikariDataSource;


        @Bean
        public DataSource dataSource() {
            // In classpath from spring-boot-starter-web
            final Properties props = new Properties();
            props.put("driverClassName", "com.mysql.jdbc.Driver");
            props.put("jdbcUrl", "jdbc:mysql://localhost:3306/master?createDatabaseIfNotExist=true");
            props.put("username", "root");
            props.put("password", "mysql");
            HikariConfig hc = new HikariConfig(props);
            HikariDataSource ds = new HikariDataSource(hc);
            return ds;
        }
