【问题描述】：

我有这门课：

    package controllers;

    import static org.junit.Assert.*;
    import static org.mockito.Mockito.mock;
    import static org.mockito.Mockito.times;
    import static org.mockito.Mockito.verify;
    import static org.mockito.Mockito.when;

    import java.util.HashSet;

    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.mockito.InjectMocks;
    import org.mockito.Mock;
    import org.mockito.MockitoAnnotations;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;


    import org.springframework.ui.Model;
    import org.springframework.web.context.WebApplicationContext;

    import com.epam.hhsystem.model.candidate.Candidate;
    import com.epam.hhsystem.services.CandidateService;
    import com.epam.hhsystem.web.controllers.CandidateMenuController;
    import org.springframework.test.context.web.WebAppConfiguration;
    import org.springframework.test.context.junit4.*;
    import org.springframework.test.web.servlet.MockMvc;
    import org.springframework.test.web.servlet.ResultActions;
    import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
    import org.springframework.test.web.servlet.setup.MockMvcBuilders;


    import org.springframework.test.web.servlet.request.*;

    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
    import static org.hamcrest.Matchers.*;
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;


    @ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
    @RunWith(SpringJUnit4ClassRunner.class)
    @WebAppConfiguration
    public class CandidateControllerTest {

        @Mock(name = "candidateService")
        private CandidateService candidateService;

        @InjectMocks
        private CandidateMenuController candidateMenuController = new CandidateMenuController();

        @Autowired
        WebApplicationContext wac;

        MockMvc mockMvc;

        @Before
        public void before() {
            MockitoAnnotations.initMocks(this);
              this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();

        }
@Test 
    public void testgoToCandidateMenuMockMvc() throws Exception { 
        //MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/goToCandidateMenu");


        MockHttpServletRequestBuilder request = MockMvcRequestBuilders.get("/goToCandidateMenu");
        ResultActions result = mockMvc.perform(request);
        result.andExpect(status().isOk());
     }
}

当我执行它时，我看到：

控制器代码：

@Controller
public class CandidateMenuController extends AbstractController {
...
@RequestMapping("/goToCandidateMenu")
    public String goToCandidateMenu() {
        return "candidateMenu";
    }
...
}

你能帮我解决我的问题吗？

【问题讨论】：

我们需要查看您的上下文。另外，你在哪里初始化mockMvc？
查看日志输出。如果您收到 404，服务器通常会告诉您原因。
为什么有人会否决这样一个恕我直言的合法问题？
@SotiriosDelimanolis 不过，我还是不明白。像stackoverflow.com/questions/596351/… 这样的问题呢？他们没有展示任何类型的研究并获得+600 的支持！由于这些反对意见，Stackoverflow 对我越来越有敌意！
7 年后，我仍然不同意。 K，这不是一个好问题，但是 OP 因他遇到的一个真正问题而被否决（我不在这里判断他的问题解决能力）。我链接的非常基本的 jQuery 问题现在有 2500 多个赞成票。 SO 仍然奖励最愚蠢、最基础的问题。我仍然认为这是错误的。

标签： java spring testing spring-mvc mocking

【解决方案1】：

您的测试设置错误，您没有正确初始化MockMvc，这在参考指南中很清楚。首先，您有两倍的初始化代码，并且您没有将调用结果分配给build 方法。所以你基本上只剩下一个空的MockMvc 对象。

@Before
public void before() {
    MockitoAnnotations.initMocks(this);
    MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
    MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
}

应该是

@Before
public void before() {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();
}

如上所述，这一切都在the reference guide 中进行了解释。

【讨论】：

对不起，我发布了错误的代码。（发布了 cmets）。我的代码就像你的变种。但我有老问题。我在帖子中修复了胡子
除此之外，在我的情况下，我在 url 的开头缺少一个正斜杠“/”

【解决方案2】：

我相信你只是没有在你的beanconfig.xml 中启用<mvc:annotation-driven>，所以你的@Controller 课程没有被注册。

添加这个

<mvc:annotation-driven></mvc:annotation-driven>

【讨论】：

【解决方案3】：

就我而言，我缺少以下注释并收到此错误。

@WebMvcTest(UserStatsController.class)
public class UserStatsControllerTest {
  ..
}

注意控制器的类，不是测试。如果您使用 @ContextConfiguration(NOT the test) 加载其他类，请确保不要加载测试类。

【讨论】：

谢谢伙计，简单但有用的答案！我正在使用 UserStatsControllerTest.class，哈哈哈 :(

【解决方案4】：

这是我的工作解决方案。希望对您有所帮助。

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
@WebAppConfiguration
public class SimpleTest  {

private MockMvc mockMvc;

@Autowired
private WebApplicationContext webApplicationContext;

@Before
public void setup() throws Exception {
    mockMvc = webAppContextSetup(webApplicationContext)
            .build();
    }

@Test
public void test() throws Exception {        
    mockMvc.perform(get("/simple")
            .contentType(MediaType.APPLICATION_JSON))
            .andExpect(status().is(200));
    }
}

【讨论】：

【解决方案5】：

如果您像我一样犯了一个非常愚蠢的“为了自己的利益而禁食”的错字，请确保您的控制器测试类与控制器类本身的名称不同。大多数人都知道这一点，但是您可能会遇到相同的错误情况，名称相同，这可能不是我立即显而易见的原因。为了进一步澄清，请确保您不要这样做：

控制器名称：MyController
测试类名：MyController

这可能会导致您的 MockMvc 测试以 404 状态失败...这不是很明显。
命名[显然]应该更像：

控制器名称：MyController
测试类名：MyControllerTest

【讨论】：

【解决方案6】：

我将此注释添加到配置类并使用它：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigWebContextLoader.class)
@WebAppConfiguration
public class ResourceTest {

   ...

   @Configuration
   @EnableWebMvc
   @ComponentScan( basePackages = { "..." } )
   static class ContextConfiguration {
   }
}

【讨论】：

这里出现了6个注解，你添加了哪一个？
您在 ContextConfiguration 和 @ContextConfiguration(loader = AnnotationConfigWebContextLoader.class) 上看到的所有内容

【解决方案7】：

我的问题是我没有 @ComponentScan() 这很尴尬。它也很难找到。我自己忽略了我的 SpringBootApplication。

【讨论】：

【解决方案8】：

以下是我在 spring mvc 中所做的，效果很好（解释为无法找到直接参考）控制器类如下

            package rndpurpose.controller;

            @RestController
            @RequestMapping("/springmvc")
            public class urlController {

                @CrossOrigin
                @RequestMapping(value = "managepostReq", method = RequestMethod.POST, headers = "Accept=application/json")
                public Map<String, Object> managepostReq()
                {
                    Map<String, Object> response = new HashMap<>();

                    //System.out.println(data);
                    response.put("status", true);

                    return response;
                }
            }

在 rnd purpose.text (package) 内部 > 创建了与我在 WebConfig.java 中的 @ComponentScan 创建的测试类相关的包

            package rndpurpose.test;

            import static org.hamcrest.Matchers.is;
            import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
            import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
            import org.json.JSONObject;
            import org.junit.Test;
            import org.springframework.core.annotation.Order;
            import org.springframework.test.web.servlet.MvcResult;
            import org.springframework.test.web.servlet.ResultActions;
            import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
            import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
            import junit.framework.Assert;

            public class UrlcontrollerTest extends JunitAbstract {

                @Test
                @Order(1)
                public void firsttestcase() throws Exception {
                /*jai ganesha*/
                    try {
                        JSONObject jsonGetData = new JSONObject();
                        jsonGetData.put("username", "name");
                        
                        ResultActions resultActions = postRequest("/springmvc/managepostReq", jsonGetData.toString());
                        MvcResult mvcResult = resultActions.andExpect(status().isOk())
                                .andDo(MockMvcResultHandlers.print())
                                .andReturn();

                        
                        JSONObject reqResponse = new JSONObject(mvcResult.getResponse().getContentAsString());
                        System.out.println(reqResponse);

                    } catch (Exception e) {
                        System.err.println("ERROR"+ e);
                    }
                }

            }

以及用于处理请求的 JunitAbstract

            package rndpurpose.test;
            import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;

【解决方案9】：

就我而言，我在 MyApplication 类上缺少 @ComponentScan("my.package.*") ，因为我的控制器与 MyApplication 类位于不同的包中。

请在调试模式下检查调试器刻度线。如果组件正在被扫描，它将显示为 Tick 标记，否则不会。

【解决方案10】：

当我的控制器未加载时遇到类似的错误，如果 spring mvc 带有基于 .xml 的调度程序 servlet，我可以通过添加 @ContextConfiguration 来修复它如下

有一个bean连接db

@EnableWebMvc
public class WebConfig  {

private static final Logger LOGGER = Logger.getLogger(WebConfig.class);

@Bean
public CommonsMultipartResolver multipartResolver() {
    final CommonsMultipartResolver resolver = new CommonsMultipartResolver();
    resolver.setMaxUploadSize(20971520);
    resolver.setMaxInMemorySize(1048576);
    return resolver;
}
@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    
     dataSource.setUrl("jdbc:postgresql://192.168.2.29:5432/trintiygisenterprise");
     dataSource.setDriverClassName("org.postgresql.Driver");
     dataSource.setUsername("postgres"); 
     dataSource.setPassword("track@123");
     
    return dataSource;
}

@Bean
public Connection getConnectionObject() {
    Connection con  = null;
    try {
        Class.forName("org.postgresql.Driver");

         con = DriverManager.getConnection("jdbc:postgresql://localhost:5432/t26",
                 "postgres", "track@123");

         System.out.println("====================CONNECTED TO DB================ "+con);
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println(e);
    }
    return con;

}

@Bean
@Autowired
public JdbcTemplate jdbcTemplate(DataSource dataSource) {

    return new JdbcTemplate(dataSource);
}
}

它会在springrest-servlet.xml中被扫描

<context:component-scan base-package="com" />
 <mvc:annotation-driven />  
<!--  <mvc:resources mapping="/*" location="/" />-->

<mvc:default-servlet-handler/>
<bean class="com.config.WebConfig"/>
</beans>

和 web.xml

    <servlet>
    <servlet-name>springrest</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>springrest</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

控制器看起来像这样

@RestController
@RequestMapping("/api")
public class bootsrapController {


/**
@GetMapping("/second")
**/
@RequestMapping(value = "second", method = RequestMethod.GET, headers = 
"Accept=application/json")
public Map<String, Object> second() 
{
    Map<String, Object> result = new HashMap<>();
    result.put("second", true);
    result.put("status", true);
return result;
}
}

测试控制器如下

public class UrlcontrollerTest extends JunitAbstract {
    @Test
@Order(1)
public void unittestcreatelayergroup(){

    try {

        System.out.println("Running test");
        
        final ResultActions resultActions = getRequest("/api/second");
        System.out.println(resultActions);
        
        final MvcResult mvcResult = resultActions
                .andDo(MockMvcResultHandlers.print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("status", is(true)))
                .andReturn(); 
}
    catch (final Exception e) {

        LOGGER.error(e.getStackTrace());

    }
}

get req 的单元测试如下

@ContextConfiguration("file:src/main/webapp/WEB-INF/springrest-servlet.xml") 
@WebAppConfiguration
public abstract class JunitAbstract {

private static final Logger LOGGER = Logger.getLogger(JunitAbstract.class);

private MockMvc mockMvc;

@Autowired
public WebApplicationContext wac;

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

public ResultActions getRequest(String url) {
    LOGGER.info("sending req--------: "+url);

    ResultActions resultActions = null;
    try {
        resultActions = this.mockMvc.perform(get(url)).andDo(print());
    } catch (Exception e) {
        LOGGER.error("Error while executing test case for get"+ e);
    }
    return resultActions;
}
