如何使用Spring为HikariCP设置数据源？

嗨,我正在尝试使用HikariCP与Spring连接池.我正在使用jdbcTempLate和JdbcdaoSupport.
这是我的数据源的spring配置文件：

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource">
    <property name="dataSourceClassName" value="oracle.jdbc.driver.OracleDriver"/>
    <property name="dataSource.url" value="jdbc:oracle:thin:@localhost:1521:XE"/>
    <property name="dataSource.user" value="username"/>
    <property name="dataSource.password" value="password"/>
</bean>

但不幸的是,生成以下错误消息：

Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.zaxxer.hikari.HikariDataSource]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.zaxxer.hikari.HikariDataSource.<init>()

谁能告诉我如何解决这个问题？

解决方法:

你需要在bean配置上编写这个结构(这是你的数据源)：

<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
    <property name="poolName" value="springHikariCP" />
    <property name="connectionTestQuery" value="SELECT 1" />
    <property name="dataSourceClassName" value="${hibernate.dataSourceClassName}" />
    <property name="maximumPoolSize" value="${hibernate.hikari.maximumPoolSize}" />
    <property name="idleTimeout" value="${hibernate.hikari.idleTimeout}" />

    <property name="dataSourceProperties">
        <props>
            <prop key="url">${dataSource.url}</prop>
            <prop key="user">${dataSource.username}</prop>
            <prop key="password">${dataSource.password}</prop>
        </props>
    </property>
</bean>

<!-- HikariCP configuration -->
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
    <constructor-arg ref="hikariConfig" />
</bean>

这是我的例子,它正在发挥作用.您只需要将属性放在hibernate.properties上并在之前设置它：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:hibernate.properties</value>
        </list>
    </property>
</bean>

Obs.：版本是
    log4j：1.2.16
    springframework：3.1.4.RELEASE
    HikariCP：1.4.0

属性文件(hibernate.properties)：

hibernate.dataSourceClassName=oracle.jdbc.pool.OracleDataSource
hibernate.hikari.maximumPoolSize=10
hibernate.hikari.idleTimeout=30000
dataSource.url=jdbc:oracle:thin:@localhost:1521:xe
dataSource.username=admin
dataSource.password=
