java - Spring Boot + Thymeleaf 的@WebAppConfiguration 和@ContextConfiguration

给定一个 Spring Boot + Thymeleaf Web 应用程序(这与 Spring 项目的 gs-consuming-rest "initial" code tree 几乎相同):

├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── hello
    │   │       ├── Application.java
    │   │       ├── Config.java
    │   │       └── Controller.java
    │   └── resources
    │       └── templates
    │           └── index.html
    └── test
        └── java
            └── hello
                └── ControllerTest.java

...用户会收到“Hello World!”的问候语。在 http://localhost:8080/，但 Spring 的“上下文”的连接似乎不适用于集成测试(ControllerTest.java):

java.lang.AssertionError: Status 
Expected :200
Actual   :404

测试中的项目布局和/或配置注释有什么问题？

src/main/webapp/ 是有意缺失的，还有 web.xml 和 WEB-INF/ 之类的东西。这里的目标是使用最少的配置，通过集成测试来测试驱动应用程序的 View 和 Controller 的开发。

血淋淋的细节如下。提前为“文字墙”道歉。

pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.1.RELEASE</version>

应用程序.java

package hello;

// ...

@SpringBootApplication
public class Application {

  public static void main(String[] args) throws Throwable {
    SpringApplication.run(Application.class, args);
  }
}

Controller .java

package hello;

@org.springframework.stereotype.Controller
public class Controller {
}

配置.java

package hello;

// ...

@Configuration
public class Config extends WebMvcConfigurerAdapter {

  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("index");
  }
}

ControllerTest.java

package hello;

// ...

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = Config.class)
public class ControllerTest {

  @Autowired
  private WebApplicationContext wac;

  private MockMvc mockMvc;

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

  @Test
  public void test() throws Exception {
    this.mockMvc
        .perform(get("/"))
        .andExpect(status().isOk());
  }
}

index.html

<!DOCTYPE html>
<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <p>Hello world!</p>
  </body>
</html>

最佳答案

感谢@M.Deinum 帮助我意识到这一点:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = Config.class)
public class ControllerTest {

...应该是:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@SpringApplicationConfiguration(classes = Application.class)
public class ControllerTest {

我想 @ContextConfiguration 用于 Spring 中的集成测试，而 @SpringApplicationConfiguration 用于 Spring 中的集成测试启动。

根据Javadoc for the latter :

Class-level annotation that is used to determine how to load and configure an ApplicationContext for integration tests.

Similar to the standard @ContextConfiguration but uses Spring Boot's SpringApplicationContextLoader.
