java - (JUNIT/Spring 3.2) 未找到线程绑定(bind)请求 : Are you referring to request attributes outside of an actual web request

我正在尝试在 spring base junit 测试类中运行一个简单的测试用例。在该脚本中，该脚本中的一种方法使用请求属性，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请求属性。

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，出现以下错误:

我找到了以下主要资源

  1. http://docs.spring.io/autorepo/docs/spring/3.2.x/spring-framework-reference/html/testing.html
  2. Unit testing a method dependent to the request context

我还在我的 web.xml 中添加了请求上下文监听器

google 上有很多解决方案，但没有一个适合我。我不知道出了什么问题我几乎花了一整天多的时间来解决这个问题，但无法弄清楚这里出了什么问题。

最后我使用了以下版本

  1. Spring - 3.2.4.RELEASE
  2. 6 月 4 日 - 4.12

我们将不胜感激。

最佳答案

在应用程序上下文初始化期间，Hibernate 在其 PersistanceFactory 初始化期间实例化一个 Document 对象，这会导致以下错误:

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

无法实例化的原因如下:

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.

在文档对象的构造函数中，您使用利用 RequestContextHolder.currentRequestAttributes() 的 UtilityServices.getUser() 方法。根据请求参数初始化对象是不好的做法。如果您需要这样做，则 been 的范围需要是“请求”，并且您需要从链接到 Spring 的 Controller 或过滤器对其进行初始化 ...

我强烈建议更改引导应用程序的方式，使其不依赖于 servlet 容器并能够轻松地对其进行测试。 Hibernate 在启动时实例化一个对象这一事实可能值得怀疑，但由于我们无法更改它，您需要通过不依赖于文档构造函数中的请求来解决它。这是 Hibernate 的 JPA 实现中的一个限制。

关于java - (JUNIT/Spring 3.2) 未找到线程绑定(bind)请求 : Are you referring to request attributes outside of an actual web request，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38995773/
