【问题描述】：
从 Junit 和 Mockito 开始，
出现了这个问题，如果我使用@Autowired，我会得到不满意的依赖异常，所有注释都像@SpringBootTest，
@ExtendWith(SpringExtension.class)。
当我不使用任何注释时，每个自动装配的对象都会出现 Nullpointer 异常。
但是，如果我没有自动装配并使用模拟，那么注释也可以正常工作。
以下是用于单元测试的控制器代码：
@ExtendWith(SpringExtension.class)
@SpringBootTest
//@ComponentScan(basePackages = "com.info.payments",
// excludeFilters = @ComponentScan.Filter(
// type = FilterType.REGEX,
// pattern = "com.info.payments.config..*"
// ))
//@EnableAutoConfiguration
@ContextConfiguration(classes = PaymentsInfoApplication.class)
class VendorControllerTest {
@Autowired
VendorController vendorController;
@Autowired
VendorRepository vendorRepository;
@Autowired
ModelMapper modelMapper;
@BeforeEach
void setUp() {
if(Objects.nonNull(vendorRepository) && vendorRepository.count() > 0){
vendorRepository.deleteAll();
}
}
@DisplayName("adding or updating Vendor")
@Test
void vendorAddUpdateTest() {
VendorRequestDTO vendorRequestDTO=new VendorRequestDTO();
vendorRequestDTO.setGuid(1L);
Vendor vendorEntityObject = modelMapper.map(vendorRequestDTO, Vendor.class);//here model mapper getting Nullpointer exception.
给定的是依赖 bean 问题异常的 slacktrace

注意：这是单元测试，在每个类测试中也观察到相同的问题，即服务、存储库
谢谢！
【问题讨论】：
-
Could not resolve placeholder 'MASTER_REDIS_SERVER_URL' in value "${MASTER_REDIS_SERVER_URL}"非常清楚出了什么问题。此外，您的测试已经注释了所有 Spring 测试注释，因此不会运行任何东西，也不会注入任何东西。 -
@M.Deinum 我的错，我在谷歌搜索后尝试了一些注释，实际上早期的跟踪是针对使用 springboottest 和其他书面注释的情况。
-
@M.Deinum，它不仅仅是关于“${MASTER_REDIS_SERVER_URL}”，它无法解析任何配置文件。如何解决这个问题，它应该自动配置依赖项，因为我确保一切都是
@Component。 -
这是全部关于那个属性。由于没有任何东西会启动并且没有任何东西可用，因此在您的测试用例中不会发生自动装配。在您的其他测试中，所有内容都被注释掉，因此没有 Spring，没有
@AUtowired将被实现。 -
由于缺少属性，应用程序未加载。测试中的
application.properties（或任何你使用的 yaml）没有该属性，所以没有加载，如果没有加载，则没有任何东西可以注入。此外，您似乎正在使用 JUnit5，请确保您没有将 JUnit5 和 4 合 1 测试混合使用。抛弃@ContextConfiguration，这一切都由@SpringBootTest处理（这就是你所需要的，你也可以删除@ExtendWith）。
