我在将HikariCP与Spring的JdbcTemplate集成时遇到错误.
我正在使用Spring 3.2.2,HikariCP 2.3.8和sybase jconn4版本7.0.0

弹簧配置：

<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
    <property name="dataSourceClassName" value="com.sybase.jdbc4.jdbc.SybDataSource" />

    <property name="connectionTestQuery" value="SELECT 1" />
    <property name="maximumPoolSize" value="100" />
    <property name="idleTimeout" value="60000" />
    <property name="jdbcUrl"
        value="jdbc:sybase:Tds:${hostname}:${port}/${dbname}" />
    <property name="username" value="${username}" />
    <property name="password" value="${password}" />
</bean>


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

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource">
        <ref bean="ds" />
    </property>
</bean>

每当上下文加载时,都会引发此错误,并且无法创建数据源

现在,有趣的部分是,如果我使用简单的代码执行此操作,它将可以完美运行.

public class JdbcTemplateFactoryTest {

    @Autowired
    HikariConfig hikariConfig;

    //@Autowired
    //HikariDataSource ds;


    @Test
    public void hikaritest(){

        HikariDataSource ds = new HikariDataSource(hikariConfig);
        JdbcTemplate jdbcTemplate = new JdbcTemplate(ds);

        assertNotNull(jdbcTemplate);
    }
}

奇怪的是,如果我取消注释弹簧来加载ds,它将失败.

花了整整一天的时间.任何建议表示赞赏

解决方法:

dataSourceClassName和jdbcUrl属性是互斥的(see the doc).您有两个选择…

1)使用dataSourceClassName：

<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
    <property name="dataSourceClassName" value="com.sybase.jdbc4.jdbc.SybDataSource" />

    <property name="connectionTestQuery" value="SELECT 1" />
    <property name="maximumPoolSize" value="100" />
    <property name="idleTimeout" value="60000" />
    <property name="username" value="${username}" />
    <property name="password" value="${password}" />
    <property name="dataSourceProperties">
       <props>
          <property name="serverName" value="${hostname}" />
          <property name="port" value="${port}" />
          <property name="databaseName" value="${dbname}" />
       </props>
    </property>
</bean>

-要么-

2)使用jdbcUrl：

<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
   <property name="jdbcUrl"
             value="jdbc:sybase:Tds:${hostname}:${port}/${dbname}" />
   <property name="connectionTestQuery" value="SELECT 1" />
   <property name="maximumPoolSize" value="100" />
   <property name="idleTimeout" value="60000" />
   <property name="username" value="${username}" />
   <property name="password" value="${password}" />
</bean>

如果您的驱动程序未自注册,则可能需要将driverClassName属性添加到选项#2.

更新：
如果您可以阅读捷克文,则可以在http://blog.prodejna.biz/2013/03/glassfish-jms-broker-perzistujici.html处阅读到相同的错误.基本上,不要使用SyDataSource,请仅使用基于jdbcUrl的方法(如果需要,可以使用driverClassName).
