SpringBoot1.4-无法找到@SpringBootConfiguration，在运行IntegrationTest时在测试错误中使用@ContextConfiguration / @SpringBootTest（class）

Question

我在Spring Boot 1.4中的一个控制器测试中面临集成测试的问题。下面的代码片段将清楚地展示项目结构：

class ExchangeControllerIT：

    public class ExchangeControllerIT extends AbstractSpringControllerIT {

      // class under test
      @Autowired
      private ExchangeController exchangeController;

      @Autowired
      private OAuth2RestTemplate restTemplate;

      @Test
      public void shouldSuccessWhileExchange() throws Exception {
        // given       
        controllerHas(mockExchangeServiceReturningStringResponse());
        // then      
        getMockMvc().perform(get(Uris.Exchange).accept(MediaType.TEXT_HTML)
                .content(asString(ExchangeControllerIT.class, "")))
                .andExpect(status().isOk())
            .andExpect(content().contentType(MediaType.parseMediaType(MediaType.TEXT_HTML + ";charset=UTF-8")));        
       }

       private void controllerHas(ExchangeService exchangeService) {
           Reflections.setField(exchangeController, "exchangeService", exchangeService);
       }

       private static ExchangeService mockExchangeServiceReturningStringResponse() {
        return new HandShakeService();           
       }
}

摘要类如下：

    public abstract class AbstractSpringControllerIT extends AbstractSpringIT{

       protected MockMvc getMockMvc() {
           return webAppContextSetup(getApplicationContext()).build();
       }
    }

AbstractSpringIT类：

    @RunWith(SpringRunner.class)
    @SpringBootTest(webEnvironment= SpringBootTest.WebEnvironment.DEFINED_PORT)
    public abstract class AbstractSpringIT {

       @Autowired(required=true)
       private GenericWebApplicationContext ctx;
       protected final GenericWebApplicationContext getApplicationContext() {
           return ctx;
       }
   }

我是Spring Boot和Tests的新手，帮助我找出原因和可能的解决方案

Answer 1

看起来即使您使用的是@SpringBootTest注释，也不包括其classes参数，您需要在上下文中指定需要加载的类才能使测试成功运行。

检查您需要哪些课程并将其包含在那里：

@SpringBootTest(classes=...)

此外，尽管可能不是最佳解决方案，但如果您不介意为测试重新加载整个弹簧上下文，则可以在测试类中使用@SpringBootConfiguration注释而不是@SpringBootTest
