spring 控制台程序
不是web程序
applicationContext.xml配置好了一些必要的bean,比如datasource等;
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
这个怎么获得数据库连接
用注解还是什么？有详细示例吗

[解决办法]
datasource不就是要配置数据源的吗？你里面配成啥了？
这是我的datasource配置你可以看一下：

beans.xml

XML code

<bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="location">            <value>classpath:jdbc.properties</value>        </property>    </bean>        <bean id="dataSource" destroy-method="close" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="driverClass" value="${jdbc.driverClassName}" />        <property name="jdbcUrl" value="${jdbc.url}" />        <property name="user" value="${jdbc.username}" />        <property name="password" value="${jdbc.password}" />        <property name="acquireIncrement" value="${c3p0.acquireIncrement}"/>        <!-- <property name="initialPoolSize" value="${c3p0.initalPoolSize}"/> -->        <property name="minPoolSize" value="${c3p0.minPoolSize}"/>        <property name="maxPoolSize" value="${c3p0.maxPoolSize}"/>        <property name="maxStatements" value="${c3p0.maxStatements}"/>        <property name="numHelperThreads" value="${c3p0.numHelperThreads}"/>        <property name="maxIdleTime" value="${c3p0.maxIdleTime}"/>            </bean>
