java-使用com.zaxxer.hikari.HikariDataSource时出错
作者：互联网
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).
