Question

我想写一个测试用例来检查我的控制器（getPersons）。这是服务器端代码。我有什么困惑我应该放在@ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/app-contest.xml"})

里面

其次，我遇到了一些错误：

无法加载应用程序上下文。找不到路径[我在@ContextConfiguration中指定]

我有这样的结构：

 restAPI
    *src/main/java
      com.company.controller
         personController.java
    *Test
      com.company.testController
         personControllerTest.java
    *src
      main
       webapp
         WEBINF
           app-context.xml


@Autowired
private PersonService personService;

@RequestMapping(value="/t2/{yy_id}/person", method=RequestMethod.GET)
@ResponseBody
public PersonInfo[] getPersons() {

    return personService.getPersons();
}

这是我的测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:WEB-INF/app-context.xml"})
@WebAppConfiguration
public class PersonControllerTest  {


@Autowired
private WebApplicationContext wac;

private MockMvc mockMvc;

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

@Autowired
private PersonService personService;

@Test
public void getPersons() throws Exception {

    this.mockMvc.perform(get("/t2/1/person")
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());

}

有人可以帮我解决一下这里有什么问题吗？

Answer 1

正如duscusion中所提到的：WEB-INF实际上并不是类路径的一部分。如果使用maven等通用模板，请使用src / main / resources或src / test / resources将app-context.xml放入。然后你可以使用'classpath：'。

将配置文件放入src / main / resources / app-context.xml并使用代码

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
...
}

或者您可以使用不同的bean配置来测试上下文。

将配置文件放入src / test / resources / test-app-context.xml并使用代码

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
...
}

Answer 2

如果您使用的是Maven，请在pom.xml中添加以下配置：

<build>
    <testResources>
                <testResource>
                    <directory>src/main/webapp</directory>
                </testResource>
    </testResources>
</build>

使用此配置，您将能够访问WEB-INF文件夹中的xml文件。来自Maven POM参考： testResources元素块包含testResource元素。它们的定义与资源元素类似，但在测试阶段自然使用。

Answer 3

通过将以下依赖项添加到pom.xml文件中来解决：

<dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>test</scope>
</dependency>

Answer 4

此异常可能有多个根本原因。对我而言，我的ockMvc无法自动配置。我通过在类级别使用BehaviorSubject解决了此异常。此注释将禁用完全自动配置，而仅应用与MVC测试相关的配置。

一种替代方法是，如果您希望加载完整的应用程序配置并使用MockMVC，则应考虑将@WebMvcTest(MyController.class)与@SpringBootTest结合使用，而不是@AutoConfigureMockMvc

无法为Spring控制器的JUnit测试加载ApplicationContext
