使用 @TestPropertySource 時，屬性始終為 null @ConfigurationProperties

Question

使用@TestPropertySource時，屬性始終為 null @ConfigurationProperties

配置文件application.yml ：

integration:
  some:
    configuration:
      userInfo: testUser

配置 class

@Component
@Data
@ConfigurationProperties(prefix="integration.some.configuration")
public class SomeProperties {    
    private String userInfo;
}

服務 class：

@Service
@RequiredArgsConstructor
@EnableConfigurationProperties(SomeProperties.class)
public class SomeServiceImpl {
        private final SomeProperties someProperties;
    public String get() {
            return someProperties.getUserInfo();
        }
}

測試夾具：

@SpringJUnitConfig({
        SomeServiceImpl.class,
        SomeProperties.class})
@TestPropertySource(properties = {
        "integration.some.configuration.userInfo=someUser"
})
class SomeServiceImplTest {
    @Autowired
    SomeServiceImpl someServiceImpl;

    @Test
    void someTest() {
       String user = someServiceImpl.get();
       ....
    } 
}

在上面的測試中，注入的用戶總是null 。

你錯過了自動裝配

@Service
@RequiredArgsConstructor
@EnableConfigurationProperties(SomeProperties.class)
public class SomeServiceImpl {

    @Autowired // <--------
    private final SomeProperties someProperties;

    public String get() {
            return someProperties.getUserInfo();
        }
}

此外，由於您將@Component放置在 SomeProperties 上，您可以刪除@EnableConfigurationProperties(SomeProperties.class)
