如何解决此bean定义重写？

Question

我已经从Spring Boot 1.5升级到Spring Boot 2.1.8。我做了一些测试，但现在失败了。我还在2.9版本中使用maven surefire插件，它也能正常工作，但如果有必要的话，我也将其升级到了2.22.0。

java prettyprint-override">@ExtendWith(SpringExtension.class)
@WebMvcTest(value = ElementController.class, secure = false)
@ContextConfiguration(classes = TestSite1Config.class)
public class ElementControllerSite1IT {
  @Autowired
  protected MockMvc mvc;
  @MockBean
  ElementService elementService;
  @BeforeEach
  public void setup() {
    when(elementService.getElementTable( ... )) //skipping args for brevity
       .thenReturn(new ElementTable());
  }

  @Configuration
  public static class TestSite1Config {
    @Bean
    @Autowired
    public ElementController elementController(final ElementService elementService) {
      return new ElementController(elementService, new ElementControllerProperties(DeploymentLocation.SITE1));
  }

  @Test
  public void failSite1ValidationWithoutId() throws Exception {
    ElementParameters params = getParams(false);
    mvc.perform(post("/element")
      .contentType(JSON)
      .andExpect(status().isBadRequest());
  }

  //more tests, but doesn't matter.
}

还有另一个类似于上述的类，但将Site1替换为Site2。

有一个ElementController

我得到这个例外：

Caused by BeanDefinitionOverrideException: Invalid bean definition with name 'elementController' defined in class path resource [ui/v2/web/ElementControllerSite1IT$TestSite1Config.class]: Cannot register bean definition [Root bean: class [null]; ... defined in class path resource [ui/v2/web/ElementControllerSite1ITConfig.class] for bean 'elementController': There is already [Generic bean: class [ui.v2.web.ElementController]; .. defined in file [...ui/v2/web/ElementController.class]] bound.

我没有编写测试，这是我继承的代码，在一个代码库中，我只是在后台处理。

Answer 1

让它与此一起工作：（对于任何偶然发现这个问题的人）

@ExtendWith(SpringExtension.class)
@AutoConfigureMockMvc
@WebMvcTest
@ContextConfiguration(classes = {ElementController.class,TestSite1Config.class})
public class ElementControllerSite1IT {
  @Autowired
  private MockMvc mvc;
  ...
  @Configruation
  public static class TestSite1Config {
    @Bean
    @Primary
    public ElementControllerProperties elementControllerProperties() { return ... }
  }
  ...
}

Answer 2

将spring.main.allow定义覆盖到application.properties

Answer 3

您可以尝试@TestProperty tySource（属性="..."：

@ExtendWith(SpringExtension.class)
@WebMvcTest(value = ElementController.class, secure = false)
@ContextConfiguration(classes = TestSite1Config.class)
@TestPropertySource(properties = {"spring.main.allow-bean-definition-overriding=true", "local.server.port=7777"})
public class ElementControllerSite1IT {
 ...
}
