Spring @ContextConfiguration如何为xml放置正确的位置

Question

在我们的项目中,我们正在编写测试以检查控制器是否返回正确的模型视图

@Test
    public void controllerReturnsModelToOverzichtpage()
    {
        ModelAndView modelView = new ModelAndView();
        KlasoverzichtController controller = new KlasoverzichtController();
        modelView = controller.showOverzicht();

        assertEquals("Klasoverzichtcontroller returns the wrong view ", modelView.getViewName(), "overzicht");
    }

这将返回异常null.

我们现在正在配置@contextconfiguration但是我们不知道如何加载位于src\main\webapp\root\WEB-INF\root-context.xml的正确的xml

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class TestOverzichtSenario{
....

此文档不够清晰,无法理解

关于如何确保contextannotation加载正确的xml的任何建议？

编辑v2

我将配置.xml文件从webINF文件夹复制到

src\main\resources\be\..a bunch of folders..\configuration\*.xml 

并将webinf中的web.xml更改为

<param-name>contextConfigLocation</param-name>
<param-value>
            classpath*:configuration/root-context.xml
            classpath*:configuration/applicationContext-security.xml
        </param-value>

现在得到错误

Answer 1

我们的测试看起来像这样(使用Maven和Spring 3.1):

@ContextConfiguration
(
  {
   "classpath:beans.xml",
   "file:src/main/webapp/WEB-INF/spring/applicationContext.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-data-servlet.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-servlet.xml"
  }
)
@RunWith(SpringJUnit4ClassRunner.class)
public class CCustomerCtrlTest
{
  @Resource private ApplicationContext m_oApplicationContext;
  @Autowired private RequestMappingHandlerAdapter m_oHandlerAdapter;
  @Autowired private RequestMappingHandlerMapping m_oHandlerMapping;
  private MockHttpServletRequest m_oRequest;
  private MockHttpServletResponse m_oResp;
  private CCustomerCtrl m_oCtrl;

// more code ....
}

Answer 2

这就是不配置的原因webapp.

据我所知,没有很好的方法可以webapp从单元测试中访问文件夹中的文件.您可以src/main/resources改为使用配置,以便可以从单元测试(如文档中所述)以及webapp(使用classpath:前缀contextConfigLocation)访问它.

Answer 3

我认为这是一个特定的maven问题.Maven不会将文件格式复制/src/main/resources到target-test文件夹.如果您绝对想要这样,那么您必须通过配置资源插件自己完成此操作.

更简单的方法是将测试特定的上下文定义放在/src/test/resources目录中并通过以下方式加载:

@ContextConfiguration(locations = { "classpath:mycontext.xml" })

Answer 4

简单的解决方案

@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/applicationContext.xml" })

Answer 5

我们用:

@ContextConfiguration(locations="file:WebContent/WEB-INF/spitterMVC-servlet.xml")

该项目是一个eclipse动态Web项目,然后路径是:

{project name}/WebContent/WEB-INF/spitterMVC-servlet.xml
