我们正在尝试为我们的 Spring-MVC Web 应用程序设置 Spring-Test-MVC。我们开始使用freemarker,一切都很好。我们决定反对它,现在正尝试用 JSP 来设置它。当测试应用程序部署在 Tomcat 上时,它正在工作。当我们运行简单的测试时:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = WebContextLoader.class, locations = { "file:src/main/webapp/WEB-INF/servlet-context.xml" })
public class SkelletonTest {

    @Inject
    private MockMvc mockMvc;

    @Test
    public void homeTest() throws Exception {
        mockMvc.perform(get("/")).andExpect(status().isOk())
                .andExpect(content().type("text/html;charset=ISO-8859-1"))
                .andExpect(content().string(containsString("Hello World!")));
    }

它说:content type not set或者如果将其删除,则内容将为空。但是,控制器将被调用,因此映射必须有效。

所以这强烈表明我们的测试没有渲染视图,但我不知道我可能缺少什么设置。

这是我们的 servlet-context.xml:

<context:component-scan base-package="package.to.controllers" />
<mvc:annotation-driven />

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="exposeContextBeansAsAttributes" value="true" />
    <property name="prefix" value="/views/" />
    <property name="suffix" value=".jsp" />
</bean>

WebContextLoader:

public class WebContextLoader extends GenericWebContextLoader {
    public WebContextLoader() {
        super("src/main/webapp", false);
    }
}

GenericWebContextLoader是 spring-test-mvc 的原创。

MockMvc 像这样设置为 Bean:

@Configuration
public class TestConfig {

    @Inject
    private WebApplicationContext wac;

    @Bean   
    public MockMvc create(){
        return (MockMvcBuilders.webApplicationContextSetup(this.wac).build());
    }
}

这就是设置。web.xml 不被测试框架使用,并且应该没有关系,因为它以前工作过。

我认为在 servlet-context 中必须有一个额外的设置。它已加载,我检查过,但对于 Tomcat 部署的应用程序来说很重要,我为前缀和后缀设置的内容只会被测试忽略。

不确定错误跟踪有多大帮助,但它是:

所以感谢任何帮助我找到问题的建议!

顺便说一句:不想再这样了,所以我跳过了 pom。我们正在使用 Spring 3.1、spring-test-mvc 1.0.0..BUILD-SNAPSHOT、jsp-ap 2.2、jstl 1.2,...如果您需要了解更多信息,我会尝试将其上传到某个地方...

使用具有以下输出的 print 方法:

MockHttpServletRequest:
         HTTP Method = GET
         Request URI = /
          Parameters = {}
             Headers = {}

             Handler:
                Type = package.to.controller.HomeController
              Method = public org.springframework.web.servlet.ModelAndView package.to.controller.HomeController.index()

  Resolved Exception:
                Type = null

        ModelAndView:
           View name = index
                View = null
           Attribute = welcome
               value = Hello World!

            FlashMap:

MockHttpServletResponse:
              Status = 200
       Error message = null
             Headers = {}
        Content type = null
                Body = 
       Forwarded URL = /views/index.jsp
      Redirected URL = null
             Cookies = []

这只是更好地显示了问题,但不是解决方案......

刚刚发现以下内容:

JSP 需要一个servlet 容器。所以看来我无法以这种方式测试我的页面......如果有人知道如何解决这个问题,请告诉我......

@Biju - 我很欣赏这个答案,它为我节省了一次旅行,我并不是想在这里拍摄信使,但我必须说,为了 Spring 团队中任何可能有动力构建更好的东西的人的利益,我我发现 MockMVC 几乎是一种琐碎和徒劳的练习。首先,不直接支持 Spring 认证。好吧,如果您侦察 StackOverflow,您可以找到解决方法。然后我自己发现,如果你有你的spring上下文配置,你可以组成的每条路径都会返回为“OK”,即使它应该返回“notFound”。好吧,无论如何,把它拿出来,让我们再也不提它了。:) 现在来发现 MockMVC 真的只是 MockMC —— 没有视图处理发生。

这不是一个真正的答案,而是一个咆哮,这意味着现在 MockMVC 也会让我失去 StackOverflow 的声誉!:) 绿巨人粉碎!

[编辑]——好吧,除了咆哮之外,看起来确实有办法解决这个问题。[稍后编辑] 不幸的是,我发现的解决方法不再可用。

添加到您的edit3上,本质上是为了JSP渲染,最终调用是

RequestDispatcher requestDispatcher = httpRequest.getRequestDispacher(jspPath)
requestDispatcher.forward(httpRequest,httpResponse)

并且RequestDispatcher实现由容器提供(因为它取决于需要如何编译jsp,将编译的jsp放在哪里等)。RequestDispatcher 的 Mock 实现只是简单地捕获转发的 JSP 页面,您只能验证 JSP 的路径是否符合您的预期。

我创建了 MockRequestDispatcher 的修改版本,它构建与 MockMvc 相同的链并将请求传递到该链以进行转发请求。这为我解决了这个问题。如果视图是在调度程序 servlet 之外呈现的(例如,通过 jsp),则需要做更多的工作。

代码在那里:https ://gist.github.com/micw/a8b20720db900762a29d

大多数工作是将其注入正确的位置。我这样做是为 MockMvc 创建了一个 RequestPostProcessor 和一些拦截 MockHttpServletRequest.getRequestDispatcher 调用的 mockito-magic。

要使用它,请将其添加到您的测试类路径并在创建 MockMvc 实例后直接调用它:

    mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
            [...]
            .build();
    WebMvcRequestDispatcherForwardFix.apply(mvc);
