这是一个非常奇怪的行为。我有一个可以正常工作的Spring启动应用程序。由于几天（我刚换的应用程序到另一个混帐回购协议，如果这意味着什么），我每次用的IntelliJ运行测试时我武功的错误：在IntelliJ社区2017.1中运行Spring启动测试时出现错误。

所以说，它无法找到测试的.properties文件我在这里声明：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = MyApplication.class)
@TestPropertySource(locations="test.properties")
@SpringBootTest
public class AudioVideoControllerTest {...}
的文件是在类路径中（src /主/ JAVA/COM/myCompany的/ myproject的/ test.properties）
现在最离奇的一部分。如果我用Eclipse（实际上是Sprig Tool Suite）打开项目并运行测试，它们就可以工作。然后我再次对IntelliJ运行测试，并且......他们工作！
因此，当我打开并刷新项目时，Eclipse/STS会进行一些更改，但我不知道它是什么。
该文件必须位于src/main/resources而不是src/main/java中，这适用于所有非java资源。 –
如果该文件专用于测试，它应该在'src/test/resources'中。您还可以尝试使用'classpath：test.properties'更改位置值。 [查看更多详情]（https://docs.spring.io/spring/docs/current/spring-framework-reference/html/integration-testing.html#testcontext-ctx-management-property-sources）。 – Thoomas
如果我将文件从'src/main/java/com/mycompany/myproject'移走，则不再有效。我猜是因为它将前缀'src/main/java/com/mycompany/myproject'作为前缀。例如，我将'test.properties'移到了'src/main/resources'中，并且出现错误：'java.io.FileNotFoundException：无法打开类路径资源[com/mycompany/myproject/test.properties]，因为它不存在'。添加'classpath：'也没有帮助。 –
