Question

我遇到Spring JAP应用程序的运行时问题。我已经定义了数据源。错误消息如下：

Info:   [EL Info]: 2015-03-13 21:31:40.932--ServerSession(1884324141)--EclipseLink, version: Eclipse Persistence Services - 2.5.0.v20130507-3faac2b

Severe:   Startup of context /SampleDb-WEB failed due to previous errors

问题是我根本没有使用Persistence.xml，我用applicationContext.xml这样定义了数据源：

...
<context:property-placeholder location="classpath:/META-INF/sample-db.properties"/>

    <bean class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close" id="dataSource">
        <property name="driverClassName" value="${database.driverClassName}"/>
        <property name="url" value="${database.url}"/>
        <property name="username" value="${database.username}"/>
        <property name="password" value="${database.password}"/>
        <property name="testOnBorrow" value="true"/>
        <property name="testOnReturn" value="true"/>
        <property name="testWhileIdle" value="true"/>
        <property name="timeBetweenEvictionRunsMillis" value="1800000"/>
        <property name="numTestsPerEvictionRun" value="3"/>
        <property name="minEvictableIdleTimeMillis" value="1800000"/>
    </bean>
...
