Question

我尝试创建某种集成测试环境，并在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＆＃39; fileService＆＃39;提交了FileService bean本身，而不是事务代理。这是例外的原因：

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

Answer 1

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，因为它会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将其回滚）

Answer 2

基于Spring Framework的documentation：

在TestContext框架中，交易由管理 TransactionalTestExecutionListener默认配置，即使你没有明确声明你的@TestExecutionListeners 考试班。但是，要启用对事务的支持，您必须这样做在PlatformTransactionManager中配置ApplicationContext bean 通过@ContextConfiguration语义加载。另外，你必须声明Spring的 @Transactional注释在类或方法级别为您的测试

您确实在PlatformTransactionManager中定义了applicationContext-db.xml，但没有在@Transactional类或FileServiceImplTest方法中添加testSaveFolder。在测试类或方法上添加@Transactional。

@ContextConfiguration不会创建事务代理
