spring - 如何测试 Spring @Conditional bean

Question

我有一个@Conditional bean -

@RestController("/user")
@ConditionalOnProperty(prefix = "user-controller", name = "enabled", havingValue = "true")
public void UserController {

@GetMapping
public String greetings() {
  return "Hello User";
}

}

它可以启用或禁用。我想创建一个测试来涵盖这两个用例。我怎样才能做到这一点？我只有一个 应用程序属性 文件:

user-controller.enabled=true

我可以将属性注入(inject) bean 并添加一个 setter 以通过代码对其进行管理，但该解决方案并不优雅:

@RestController("/user")
@ConditionalOnProperty(prefix = "user-controller", name = "enabled", havingValue = "true")
public void UserController {

@Value("${user-controller.enabled}")
private boolean enabled;

public void setEnabled(boolean enabled) {
 this.enabled = enabled;
}

@GetMapping
public String greetings() {
  return enabled ? "Hello User" : "Endpoint is disabled";
}

}

像这样

假设您使用 SpringBoot 2，您可能会像这样进行测试:

public class UserControllerTest {

  private final ApplicationContextRunner runner = new ApplicationContextRunner()
      .withConfiguration(UserConfigurations.of(UserController.class));

  @Test
  public void testShouldBeDisabled() {
    runner.withPropertyValues("user-controller.enabled=false")
        .run(context -> assertThat(context).doesNotHaveBean("userController "));
  }
}
