Spring JUnit 测试中未加载 ServletRegistrationBean

Question

我正在尝试在我的 Spring 启动应用程序中测试 Rest 服务。当我运行或调试整个应用程序时，我可以成功地执行 ir。 Spring Bott start 显示以下几行，其中包括：

2015-07-02 17:04:10.654  INFO 3084 --- [           main] org.apache.catalina.core.StandardEngine  : Starting Servlet Engine: Apache Tomcat/8.0.20
2015-07-02 17:04:10.769  INFO 3084 --- [ost-startStop-1] o.a.c.c.C.[Tomcat].[localhost].[/]       : Initializing Spring embedded WebApplicationContext
2015-07-02 17:04:10.769  INFO 3084 --- [ost-startStop-1] o.s.web.context.ContextLoader            : Root WebApplicationContext: initialization completed in 2449 ms
2015-07-02 17:04:11.219  INFO 3084 --- [ost-startStop-1] o.s.b.c.e.ServletRegistrationBean        : Mapping servlet: 'dispatcherServlet' to [/]
2015-07-02 17:04:11.224  INFO 3084 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean  : Mapping filter: 'characterEncodingFilter' to: [/*]
2015-07-02 17:04:11.224  INFO 3084 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean  : Mapping filter: 'hiddenHttpMethodFilter' to: [/*]

但是，当我运行我的 JUnit 测试时，除了 servlet 未初始化外，一切正常，请求映射正常等。的确，上面那些行没有出现。

这很奇怪，因为我运行使用与运行整个应用程序相同的 Application.class 进行测试。这是 Application.class:

@ImportResource("classpath:/META-INF/spring/integration/spring-integration-context.xml")
@SpringBootApplication
@WebAppConfiguration
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

并且来自我的 JUnit 测试：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
public class CatalogRestControllerTests extends AbstractTransactionalJUnit4SpringContextTests {
...
@Test
public void someTest() {...}
}

我一直在尝试解决 servlet-context.xml 和 web.xml 配置文件中的问题。但我认为问题不存在，因为它适用于 Application.class

有什么想法吗？谢谢！

找到了。

看来我的 JUnit class 上缺少 @WebIntegrationTest 注释。这就是文档所说的 @WebIntegrationTest:

Test class annotation signifying that the tests are "web integration tests" and therefore require full startup in the same way as a production application (listening on normal ports). Normally used in conjunction with @SpringApplicationConfiguration,

This annotation can be used as an alternative to @IntegrationTest and @WebAppConfiguration.
