spring-boot - 无法加载TestContextBootstrapper-非Web应用程序的Spring-boot集成测试错误

我正在使用基于gradle项目的spring-boot时间表。当我在src / main / java下通过主类运行时，调度程序运行良好（使用调试器或通过执行spring-boot jar）。对于集成测试-我创建了一个与java并行的新的integrationTest目录。

For integration test, the class that i created is as follows.
---------------
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootApplication
@ContextHierarchy({
        @ContextConfiguration(name = "testContext", classes = ConfigCommons.class, loader = SpringApplicationContextLoader.class),
})


@TestPropertySource("classpath:integrationtest.properties")

//@IntegrationTest


public class IntegrationUseCase {

    BeanA beana;
    BeanB beanb;

    @Before
    public void setup() {
        beana = new BeanA();
        beanb = new BeanB();
    }

    @Test
    public void testUseCase() {
      // logic that uses beanA and beanB
    }
}
---------------

Have following questions:
1. I have not leveraged autowired. Is there a way I can do that?
2. While buiding the project - Getting an error that TestContextBootstrapper cannot be loaded. I am using the following spring-boot packages-
"org.springframework.boot:spring-boot-starter-test:1.4.0.RELEASE". However, when I commented out this test class, the project buolds and runs fine. Does anyone know what is happening here?
 The log is:

java.lang.IllegalStateException: Could not load TestContextBootstrapper [null]. Specify @BootstrapWith's 'value' attribute or make the default bootstrapper class available.

最佳答案

我有一个类似的问题。 pom.xml文件中的依赖项存在问题。可能有很多原因：版本冲突，或两次声明相同依赖项的冲突：在当前pom.xml和父pom.xml中，例如使用不同的版本。
