java - 在 IntelliJ Community 2017.1 中运行 Spring 启动测试时出错

Question

这是一种非常奇怪的行为。我有一个运行良好的 Spring boot 应用程序。几天以来(我刚刚将应用程序切换到另一个 Git 存储库，如果这意味着什么的话)每次我使用 IntelliJ 运行测试时都会出现错误:

java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:124) at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:83) at org.springframework.test.context.web.ServletTestExecutionListener.setUpRequestContextIfNecessary(ServletTestExecutionListener.java:189) at org.springframework.test.context.web.ServletTestExecutionListener.prepareTestInstance(ServletTestExecutionListener.java:131) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:230) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:228) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:287) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:289) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:247) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:94) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:191) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:51) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.IllegalStateException: Failed to add PropertySource to Environment at org.springframework.test.context.support.TestPropertySourceUtils.addPropertiesFilesToEnvironment(TestPropertySourceUtils.java:198) at org.springframework.boot.test.context.SpringBootContextLoader.loadContext(SpringBootContextLoader.java:100) at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContextInternal(DefaultCacheAwareContextLoaderDelegate.java:98) at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:116) ... 24 common frames omitted Caused by: java.io.FileNotFoundException: class path resource [com/mycompany/myproject/test.properties] cannot be opened because it does not exist at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:172) at org.springframework.core.io.support.EncodedResource.getInputStream(EncodedResource.java:154) at org.springframework.core.io.support.PropertiesLoaderUtils.fillProperties(PropertiesLoaderUtils.java:98) at org.springframework.core.io.support.PropertiesLoaderUtils.fillProperties(PropertiesLoaderUtils.java:72) at org.springframework.core.io.support.PropertiesLoaderUtils.loadProperties(PropertiesLoaderUtils.java:58) at org.springframework.core.io.support.ResourcePropertySource.(ResourcePropertySource.java:84) at org.springframework.test.context.support.TestPropertySourceUtils.addPropertiesFilesToEnvironment(TestPropertySourceUtils.java:194) ... 27 common frames omitted 09:54:42.723 [main] DEBUG org.springframework.test.context.support.AbstractDirtiesContextTestExecutionListener -

Process finished with exit code -1

所以它说找不到我在这里声明的 test.properties 文件:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = MyApplication.class)
@TestPropertySource(locations="test.properties")
@SpringBootTest
public class AudioVideoControllerTest {...}

该文件位于类路径 (src/main/java/com/mycompany/myproject/test.properties)

现在是最奇怪的部分。如果我使用 Eclipse(实际上是 Sprig Tool Suite)打开项目并运行测试，它们就会工作。然后我再次在 IntelliJ 上运行测试......它们工作了!

所以看起来当我打开并刷新项目时 Eclipse/STS 做了一些更改，但我想知道它是什么。

解决方案是将 test.properties 文件拖到另一个文件夹，让 IntelliJ 更新引用，然后再次将 test.properties 文件移回根文件夹，并再次让 IntelliJ 更新所有引用。
