hibernate hikaricp 数据源

Question

我尝试将我的 webapp 的连接池从 c3p0 更改为 hikaricp。

这是我的配置。

<bean id="dataSource"
    class="org.hibernate.hikaricp.internal.HikariCPConnectionProvider">

    <property name="dataSourceClassName" value="${hikari.dataSourceClassName}" />
    <property name="maximumPoolSize" value="${hikari.maximumPoolSize}" />
    <property name="maxLifetime" value="${hikari.maxLifetime}" />
    <property name="idleTimeout" value="${hikari.idleTimeout}" />

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

我收到一个错误。

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'dataSourceClassName' of bean class [org.hibernate.hikaricp.internal.HikariCPConnectionProvider]: Bean property 'dataSourceClassName' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

在此先感谢您的帮助。

org.hibernate.hikaricp.internal.HikariCPConnectionProvider 不是 javax.sql.DataSource。它是 Hibernate 的内部组件。

更改您的配置以使用 com.zaxxer.hikari.HikariDataSource 而不是 org.hibernate.hikaricp.internal.HikariCPConnectionProvider
