java - Spring junit 测试不工作

Question

我有一个带有 Java 配置类的 Spring (4.2.5) 项目。这些在正常运行项目时有效，但我无法让我的测试工作。在下面的测试中，repo 为 null。

@ContextConfiguration(classes = { HibernateConfiguration.class })
public class TestTest {

    @Autowired
    private InstituteRepository repo;

    //some test
}

如果我添加 @RunWith(SpringJUnit4ClassRunner.class) 注释，我会得到一个异常

感谢任何帮助。

如果我将 springframework 依赖版本更改为 4.1.3，则测试有效。 4.2.5 需要不同的配置吗？ HibernateConfiguration 如下

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = { "myapp.services" })
@EnableJpaRepositories("myapp.repositories")
@Import({ HSQLConfiguration.class, MySQLConfiguration.class })
public class HibernateConfiguration {
}

其中DataSource和Properties在HSQLConfiguration和MySQLConfiguration中定义，这是根据 Activity 配置文件选择的。

经过更多谷歌搜索后，我发现 this issue ，在检查我的依赖项后，我发现我的 Maven 依赖项下有 spring-core-4.1.9，并且我没有在我的 POM 中包含它的依赖项。添加依赖项后，我在 Maven 依赖项下看到了 jar，但出现构建路径错误:

Project 'myapp' is missing required library: 'C:\Users\user\.m2\repository\org\springframework\spring-core\4.1.9.RELEASE\spring-core-4.1.9.RELEASE.jar' 

这是我的 POM 文件

构建路径问题似乎与 Eclipse 有关，从命令行运行测试有效!

如果问题仅出现在 Eclipse 上，您将通过执行以下操作来修复它:Project->Clean 右键单击​​项目:Maven->Update dependency
