spring - JUnit：弹簧配置

Question

我尝试给控制器写一个测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="/WEB-INF/spring/root-context.xml")
public class ContactServiceTest {

    private MockHttpServletRequest request;
    private MockHttpServletResponse response;
    private ContactController controller;
    private AnnotationMethodHandlerAdapter adapter;

    @Autowired
    private ApplicationContext applicationContext;

    @Before
    public void setUp() {
        request    = new MockHttpServletRequest();
        response   = new MockHttpServletResponse();
        response.setOutputStreamAccessAllowed(true);
        controller = new ContactController();
        adapter = new AnnotationMethodHandlerAdapter();
    }

    @Test
    public void getTest() throws Exception {
        request.setRequestURI("/index");
        request.setMethod("GET");
        adapter.handle(request, response, controller);
        System.out.println(response.getContentAsString());
    }
}

根上下文.xml

好吧，根据我创建的以下目录结构的建议，我对这个主题有同样的问题：

<proj>
   src
      test
         WEB-INF
             spring
                appServlet
                     controllers.xml
                     servlet-context.xml
                  root-context.xml
                  data.xml
                  security.xml

现在我有这样的例外：

您当前的错误在异常堆栈中；您的依赖项中似乎缺少 javassist，至少在测试依赖项中是这样。它可能被声明为仅运行时依赖项（尽管这些通常也用于测试阶段，但我不知道您当前使用的是哪个构建系统。）

编辑：我看到底部还有另一个（可能不相关的）错误；您使用的是哪个版本的 Spring？检查Spring 论坛上的此线程以及 Spring 2.5/Junit > 4.4 可能的不兼容性。

错误信息很清楚：

在类路径资源 [WEB-INF/spring/data.xml] 中定义名称为“transactionManager”的 bean 创建错误：并且在设置 bean 属性“sessionFactory”时无法解析对 bean“sessionFactory”的引用；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建类路径资源 [WEB-INF/spring/data.xml] 中定义的名称为“sessionFactory”的 bean 时出错：

您的 sessionFactory 设置不正确，请向我们展示data.xml

请检查您是否配置了事务管理器。下面将举一个小例子。看看您的 data.xml 也会很有趣。
