如何使用JUNIT测试spring jdbcTemplate？

Question

我有一个要测试的DAO，它使用jdbcTemplate。春天的jdbcTemplate上面有一个datasoruce属性，需要对其进行设置才能使其正常工作。但是，当运行JUNIT测试时，数据源不存在，并且Bean创建失败。如何设置jdbcTemplate的数据源以在JUNIT测试用例中工作？

任何帮助表示赞赏。

谢谢

如何使用 Spring 测试模拟的 JNDI 数据源？

我没有使用 spring 文件中定义的数据源，而是创建了一个新的数据源：

<bean id="thisDatasource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource"
p:driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
p:url="jdbc:sqlserver://sqlserver:1234;databaseName=myTables"
p:username="userid"
p:password="passw0rd" /> 


<bean id="databaseUserDAOTest" 
class="com.spring.security.custom.user.detail.DatabaseUserDAO" >
<!-- Inject the datasource of the jdbcTemplate -->
<property name="dataSource" ref="thisDatasource" />        
</bean>
