Question

我使用Spring Framework 2.5.6 我在spring-beans.xml文件中定义了以下dataSource，我用它来连接我的远程数据库：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/sample"/>
    <property name="username" value="root"/>
    <property name="password" value="root"/>

</bean>

这就是我的jUnit集成测试的样子：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "spring-beans.xml")
public class MyIntegrationTest {

   @Autowired
   DataSource dataSource;

}

我已将spring-beans.xml文件复制到我上传的测试用例代码所在的同一个包中。

但是，当我运行测试用例时，我得到以下异常：

为什么会发生这种情况的任何想法？

Answer 1

您需要将spring-beans.xml放入类路径中 - 而不是源代码所在的包。

如果您使用Maven或Gradle构建，请将文件放在 src / test / resources 中。

否则，将它放在任何地方，并在测试夹具的设置中用FileSystemXmlApplicationContext手动加载它。

Answer 2

如果您使用的是Maven，则应使用src / test / resources文件夹。 Maven可以在运行测试时将其复制。
