java之JerseyTest如何使用SpringBoot的上下文进行测试

Injection of autowired dependencies failed

但它不使用任何组件。

这是一个测试数据库的简单测试，它正在运行:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = MyApplication.class) 
public class CommonRepositoryTest { 
 
    @Autowired 
    private MyRepository myRepository; 
 
    @Test 
    public void testDatabaseChangeLogsSize() { 
        int resultSize = myRepository.getTableRowSize(MyTable.TABLE_NAME); 
        System.out.println("MyTable result list size: "+resultSize); 
        assertTrue("MyTable table should has at least one row!", resultSize>0); 
    } 
 
} 

但是这个 REST 测试器不工作:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = MyApplication.class) 
public class SampleResourceTest extends JerseyTest { 
 
    @Override 
    protected Application configure() { 
        ApplicationContext context = new AnnotationConfigApplicationContext(MyApplication.class); 
        return new ResourceConfig(SampleResource.class).property("contextConfig", context); 
    } 
 
    @Test 
    public void testSampleGet() throws Exception { 
        long id = 1; 
        String name = "name"; 
        SampleDomainModel sampleDomainModel = new SampleDomainModel(); 
        sampleDomainModel.setId(id); 
        sampleDomainModel.setName(name); 
        Response response = target("/sampleresource/samplepath/" + id).queryParam(name).request().get(Response.class); 
        SampleDomainModel responseSampleDomainModel = response.readEntity(SampleDomainModel.class); 
        assertEquals(sampleDomainModel.getId(), responseSampleDomainModel.getId()); 
    } 
 
} 

如您所见，它必须覆盖 JerseyTest 中的 configure() 方法。 我认为问题在于，AnnotationConfigApplicationContext 可能无法加载任何内容(？)。 @SpringApplicationConfiguration(classes = MyApplication.class) 注释加载了上下文，但是 new AnnotationConfigApplicationContext(MyApplication.class) 代码可能会失败，它没有完整的上下文。

如果我用模拟替换代码，它就可以工作(但这不是一个好方法):

@Override 
protected Application configure() { 
    ApplicationContext mockContext = Mockito.mock(ApplicationContext.class); 
    return new ResourceConfig(SampleResource.class).property("contextConfig", mockContext); 
} 

失败信息是:
