（JUNIT / Spring 3.2）未找到线程绑定请求：您是指实际Web请求之外的请求属性

时间：2016-08-17 11:47:24

标签： java spring unit-testing spring-mvc junit

我试图在spring base junit测试类中运行一个简单的测试用例。在该脚本中，该脚本中的一个方法是使用请求属性，如下所示：

ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
return (User) attr.getRequest().getSession().getAttribute("user");

所以我需要在运行测试脚本之前设置request属性。

测试脚本是

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/SpringConfig-servlet.xml"})
@WebAppConfiguration
public class DocumentTest {

//@Autowired
//protected SessionFactory sessionFactory;

@Autowired
protected SetUpScript setUpScript;

 @Autowired MockHttpSession session;

@Autowired MockHttpServletRequest request;


@Before
public void setup() {
    //Session session = sessionFactory.openSession();
   // TransactionSynchronizationManager.bindResource(sessionFactory,new SessionHolder(session));
    //MockHttpServletRequest request = new MockHttpServletRequest();
    //MockHttpSession session = new MockHttpSession();
    request.setSession(session);
    RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(request));
}

@Test
public void test() {
    setUpScript.saveDocument();
}



}

但它没有按预期工作，我收到了以下错误：

我找到了以下主要资源

  2. Unit testing a method dependent to the request context

    google上有许多解决方案，但它们都不适用于我。我不知道什么是错的我几乎花了一整天时间来解决这个问题但却无法弄明白，这里出了什么问题。

    最后我使用的是以下版本

    1. 春天 - 3.2.4.RELEASE
    2. Junit - 4.12

      3. 任何帮助都会被激活。

答案 0 :(得分：0)

在初始化应用程序上下文期间，Hibernate在初始化它的PersistanceFactory期间实例化一个Document对象，它会导致以下错误：

org.hibernate.InstantiationException: could not instantiate test objectorg.devdarshan.beans.Document

你无法实例化它的原因只是吼叫：

Caused by: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

在Document Object的构造函数上，您使用了利用RequestContextHolder.currentRequestAttributes（）的UtilityServices.getUser（）方法。 根据请求参数初始化对象是不好的做法。如果你需要这样做，那里的范围需要是“请求”，你需要从控制器或链接到Spring的过滤器初始化它......

我强烈建议您更改引导应用程序的方式，以便不依赖于servlet容器并能够轻松地对其进行测试。 Hibernate在启动时实例化对象的事实可能会有问题，但由于我们无法更改它，因此您需要通过不依赖于Document的constuctor中的请求来解决它。这是Hibernate的JPA实现的一个限制。
