@WebAppConfiguration and @ContextConfiguration for Spring Boot + Thymeleaf
提问by Tommy Stanton
Given a Spring Boot + Thymeleaf web application (this is nearly identical to the Spring project's gs-consuming-rest "initial" code tree):
给定一个 Spring Boot + Thymeleaf Web 应用程序（这几乎与 Spring 项目的gs-consume -rest “初始”代码树相同）：
├── pom.xml
└── src
├── main
│?? ├── java
│?? │?? └── hello
│?? │?? ├── Application.java
│?? │?? ├── Config.java
│?? │?? └── Controller.java
│?? └── resources
│?? └── templates
│?? └── index.html
└── test
└── java
└── hello
└── ControllerTest.java
...the user is greeted just fine with "Hello World!" at http://localhost:8080/, but the wiring of Spring's "context" does not seem to apply within the integration test (ControllerTest.java):
...用户会收到“Hello World！”的问候。at 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
What is wrong with the project layout, and/or the configuration annotationsin the test?
测试中的项目布局和/或配置注释有什么问题？
src/main/webapp/is intentionally missing, along with things like web.xmland WEB-INF/. The goal here is to use minimal configuration, with an integration test to test-drive the development of the view and controller of the application.
src/main/webapp/故意丢失，以及诸如web.xml和之类的东西WEB-INF/。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视图和控制器的开发。

Thanks to @M.Deinum for helping me to realize that:
感谢@M.Deinum 帮助我意识到：
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = Config.class)
public class ControllerTest {
...should be:
...应该：
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@SpringApplicationConfiguration(classes = Application.class)
public class ControllerTest {
I suppose that @ContextConfigurationis meant for integration tests in Spring, whereas @SpringApplicationConfigurationis meant for integration tests in Spring Boot.
我想这@ContextConfiguration是用于Spring 中的集成测试，而@SpringApplicationConfiguration用于Spring Boot 中的集成测试。
According to the 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.
用于确定如何为集成测试加载和配置 ApplicationContext 的类级别注释。
与标准的@ContextConfiguration 类似，但使用 Spring Boot 的 SpringApplicationContextLoader。
