java - @ContextConfiguration 不创建事务代理

我正在尝试创建某种集成测试环境，但当测试上下文框架没有为我的 bean 创建事务代理时遇到问题。我的代码:

JUnit 类:FileServiceImplTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextHierarchy({
        @ContextConfiguration(value = "file:src/main/webapp/WEB-INF/spring/applicationContext-db.xml"),
        @ContextConfiguration(value = "file:src/main/webapp/WEB-INF/spring/applicationContext.xml")
})
public class FileServiceImplTest {

    @Autowired
    private FileService fileService;

    @Test
    public void testSaveFolder() {
        FolderDTO rootFolder = new FolderDTO();
        rootFolder.setName("ROOT");
        rootFolder.setParentId(null);
        rootFolder.setIdPath("/");
        rootFolder.setPath("/");

        fileService.saveFile(rootFolder);

        List<AbstractFileDTO> rootFiles = fileService.getRootFiles();

        assertEquals(1, rootFiles.size());

        AbstractFileDTO abstractFileDTO = rootFiles.get(0);

        assertEquals(rootFolder, abstractFileDTO);

    }

}

测试上下文框架工作注入(inject)“fileService”，归档 FileService bean 本身，而不是事务代理。异常原因:

当我在 tomcat 下运行此代码时，一切正常，仅在运行测试期间才会出现问题。请帮助解决这个问题。

最佳答案

我发现我必须将 @EnableTransactionManagement 添加到我的配置中。在此之前，Spring 没有运行 SpringTransactionAnnotationParser 并将代理事务方法添加到我的 bean 中。我只将它添加到一个测试中，因为它将使所有测试的运行方式与测试框架想要的不同(管理事务本身并自动回滚它们)

关于java - @ContextConfiguration 不创建事务代理，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35483225/
