數據源注入拋出異常

我使用了Spring Framework 2.5.6 我在春天的beans.xml文件中定義的數據源之後，我才能用在我的遠程數據庫連接：數據源注入拋出異常

<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>

這是我的JUnit集成測試的樣子：

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

    @Autowired 
    DataSource dataSource; 

}

我在同一個包複製的彈簧beans.xml的文件，其中我已經上傳所在的測試用例代碼。

但是我出現以下情況例外，當我運行測試用例：

任何想法，爲什麼這可能發生？

它正在尋找名爲test的目錄中的xml文件，但沒有找到它。測試目錄必須位於您認爲的地方以外的地方。 – Julian

您需要將spring-beans.xml放入類路徑中 - 而不是源代碼所在的包。

如果您使用Maven或Gradle構建，則將文件放入src/test/resources。

否則，將其放在任何位置，並手動將其與FileSystemXmlApplicationContext一起加載到測試夾具的設置中。

我在setUpBeforeClass中編寫了這段代碼：ApplicationContext context = new FileSystemXmlApplicationContext（「/ src/main/resources/spring-beans.xml」）;但是，我如何使用上下文變量來加載@Autowired DataSource數據源中的數據？ – SteveSt

如果您使用的是Maven，您應該使用src/test/resources文件夾。運行測試時，Maven可以複製它。

我使用的是正確的maven。但是測試不在src/test/java文件夾中，而是在src/main/java中的另一個文件夾中。我使用src/main/resources文件夾，但它仍然沒有找到它 – SteveSt
