我正在尝试使用 spring 测试框架为我的控制器创建一些测试。

在这篇文章之后：http: //blog.springsource.org/2012/11/12/spring-framework-3-2-rc1-spring-mvc-test-framework/我创建了这个测试类

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("classpath:testContext.xml")
public class ServiceRequestControllerTest {

    @Autowired
    private WebApplicationContext wac;

    @Autowired
    private ServiceRequestController productController;

    @Autowired
    private WSServiceRequestIO wsServiceRequestIO;
    @Autowired
    private Open311ResponseMarshaller open311ResponseMarshaller;
    @Autowired
    private Open311GETQueryStringParser open311GETQueryStringParser;
    @Autowired
    private Open311POSTQueryStringParser open311POSTRequestParser;
    @Autowired
    private Open311ResponseFactory responseFactory;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void testTest() throws Exception {
        this.mockMvc.perform(get("/requests"));
    }
}

我的 testContext.xml 是

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <bean class="org.mockito.Mockito" factory-method="mock">
        <constructor-arg value="utils.webservice.WSServiceRequestIO" />
    </bean>

    <bean class="org.mockito.Mockito" factory-method="mock">
        <constructor-arg value="open311.model.Open311ResponseMarshaller" />
    </bean>

    <bean class="org.mockito.Mockito" factory-method="mock">
        <constructor-arg
            value="open311.utils.Open311POSTQueryStringParser" />
    </bean>

    <bean class="org.mockito.Mockito" factory-method="mock">
        <constructor-arg
            value="open311.utils.Open311GETQueryStringParser" />
    </bean>

    <bean class="org.mockito.Mockito" factory-method="mock">
        <constructor-arg
            value="open311.model.Open311ResponseFactory" />
    </bean>


    <context:component-scan base-package="open311.controller" />
    <mvc:annotation-driven />

    <mvc:resources mapping="/services*" location="/resources/" />



</beans>

现在，当我运行测试时，我会收到很多消息，例如：

2013-04-19 14:33:34 INFO  GenericTypeResolver:216 - Could not determine the target type for type argument [T] for method [public static <T> T org.mockito.Mockito.mock(java.lang.Class<T>)].

所以通过 mockito 推断类型存在一些问题，但是当我进入调试模式并检查我的控制器时，我仍然可以看到对象被正确注入。（我@Autowire在我的控制器中使用注释）。

无论如何，当我尝试运行此测试时，由于以下原因导致测试失败

什么可能是我的问题的根源？我认为我遵循了本教程的每一步。

这NoSuchMethodError表明您的测试类路径上可能有不兼容的 Servlet API 版本。

此外，您需要ServiceRequestController在测试 XML 配置中包含 Spring MVC 配置以及 bean 定义，可以直接通过导入，也可以通过@ContextConfiguration.
