我有一个spring和hibernate应用程序，我们正试图从Jboss移植到WAS Liberty配置文件。当弹簧工厂初始化时，我得到低于错误

我的服务器具有以下数据源配置

 <dataSource id="MyDS" jdbcDriverRef="Oracle" jndiName="jdbc/myDS">

应用程序上下文中的数据源bean定义如下

<bean id="myDatasource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="jdbc/myDS" />
    </bean>

我很感激帮助。这似乎与类加载有关，但我无法弄明白。

Answer 1

尝试为数据源bean定义指定以下属性：

<bean id="myDatasource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="jdbc/myDS"/>
        <property name="lookupOnStartup" value="false"/>
        <property name="cache" value="true" />
        <property name="proxyInterface"  value="javax.sql.DataSource" />
    </bean>

Answer 2

proxyInterface解决方案适用于WAS 8.5.5 Liberty Profile。在WAS 7中，这也可作为替代解决方案：

<jee:jndi-lookup id="WASdataSource" jndi-name="java:comp/env/jdbc/admt" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.WebSphereDataSourceAdapter">
        <property name="targetDataSource" ref="WASdataSource"/>
</bean>
