java - 无法加载 ApplicationContext : IllegalArgumentException

Question

我有一个使用 Maven 构建的 Java 项目，我确信我遇到了一些愚蠢的配置问题。

每当我尝试通过mvn package 打包我的代码时，我都会得到一个IllegalArgumentException。所有上下文文件都已正确加载，但在 ConfigurationClassParser 类中解析它们时出现问题。

在 TestContext.getApplicationContext 处放置一个断点并在 Eclipse 中重新运行测试，我能够看到它抛出异常的位置:在 ConfigurationClassParser 的 getImports 方法中。 逻辑如下:

if (visited.add(className)) {
        AnnotationMetadata metadata = metadataReaderFactory.getMetadataReader(className).getAnnotationMetadata();
        for (String annotationType : metadata.getAnnotationTypes()) {
            imports = getImports(annotationType, imports, visited);
        }

当它尝试从 java.lang.annotation.Target 类获取 AnnotationMetadata 时抛出异常。我不确定如何通过我的配置解决这个问题。我没有在我的任何 bean 类或测试类中导入该类。

如果需要，我很乐意发布我配置的任何其他方面。我的测试类正在扩展 AbstractJUnit4SpringContextTests，我使用的是 JUnit 4.7 和 Spring Core 3.2.1.RELEASE。

如果有任何建设性的反馈，我将不胜感激。

我能够通过将我的 Spring 版本从 3.2.0.RELEASE 更新到 4.0.5.RELEASE 来解决这个问题，其中堆栈跟踪实际上给了我它失败的原因:找不到变量值。未加载属性文件。

希望这可以帮助将来的其他人，以防他们使用 Spring 3.2.0.RELEASE.... :-/–
