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。但是，我们决定反对它，现在正尝试使用JSP进行设置。当测试应用程序部署在Tomcat上时，它就可以正常工作。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，因此映射必须起作用。

因此，这强烈暗示我们的测试未呈现该视图，但是我不知道可能缺少什么设置。

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的原始版本。

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。测试框架未使用web.xml，因为它之前已经在工作，所以无关紧要。

我认为servlet上下文中必须有其他设置。我检查了它的负载，但是对于Tomcat部署的应用来说，它很重要，但是我为它设置的前缀和后缀将被测试忽略。

不知道错误跟踪将有多大帮助，但是这里是：

因此，感谢您提供任何有助于我找出问题的建议！

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…

使用了以下输出的打印方法：

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 = []

哪个更好地显示了问题，但没有解决方案…

刚刚发现以下内容：

JSP需要一个servlet容器。因此，看来我无法以这种方式测试我的页面…如果任何人有解决此问题的想法，请告诉我。

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