spring - 使用 Spring 和 Maven 进行测试 : applicationContext

Question

这个问题似乎很古老，但我仍然找不到解决方案..

我正在尝试运行简单的测试:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/applicationContext.xml", "/PersonsPopulateTest-context.xml"})
@Transactional
public class PersonsPopulateTest {

文件位于:

src
   main
      resources
           applicationContext.xml

和

src        
   test
      resources
          PersonsPopulateTest-context.xml 

因此，在构建这些文件后，这些文件位于 target/classes 和 target/test-classes

但是 mvn test 命令仍然显示:Failed to load ApplicationContext

官方文档怎么说:

@RunWith(SpringJUnit4ClassRunner.class)
// ApplicationContext will be loaded from "/applicationContext.xml" and "/applicationContext-test.xml"
// in the root of the classpath
@ContextConfiguration(locations={"/applicationContext.xml", "/applicationContext-test.xml"})
public class MyTest {
    // class body...
}

我哪里做错了？

谢谢， 弗莱基米尔

我认为 Maven 根本没有包含来自 main/resources 的 XML 文件。

您可以尝试明确指定要在 pom.xml 中包含的内容。

如果以下配置有效，请告诉我:

    <!-- Add this directly after the <build>-opening tag -->
    <resources>
        <resource>
            <filtering>true</filtering>
            <directory>src/test/resources</directory>
            <includes>
                <include>**/*.properties</include>
            </includes>
            <excludes>
                <exclude>**/*local.properties</exclude>
            </excludes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
        </resource>
    </resources>

这是我在你的情况下使用的东西。如果您没有要包含的属性文件，您可以对其进行编辑。
