无法在 Spring Boot 测试中加载类 [pg-uuid]

技术标签:
【中文标题】无法在 Spring Boot 测试中加载类 [pg-uuid]【英文标题】：Unable to load class [pg-uuid] in spring boot test 【发布时间】：2020-01-22 19:37:46 【问题描述】：我在运行 Spring Boot 测试时遇到异常。 我在我的一个模型中的一个属性上使用 pg-uuid。
@org.hibernate.annotations.Type(type = "pg-uuid")
private UUID userUuid;
当我的测试用例被忽略时，我的应用程序运行顺利，但是当我运行测试用例时，我收到了这个错误。
原因：java.lang.ClassNotFoundException：无法加载请求的类：pg-uuid
我的完整测试课：
@NoArgsConstructor
@RunWith(SpringRunner.class)
@WebMvcTest(AuthController.class)
public class AuthControllerTest
@Autowired
MockMvc mockMvc;
@MockBean
UserDetailsService userDetailsService;
@org.junit.jupiter.api.BeforeEach
void setUp()
List<User> mockUserList= new UsersUtil().getUserList();
@org.junit.jupiter.api.AfterEach
void tearDown()
@Test
public void login() throws Exception
User user = new User();
user.setEmail("abc@example.com");
user.setPassword("123456");
try
LoginResponseBean loginResponseBean =userDetailsService.login(user);
assertThat(loginResponseBean!=null).isTrue();
assertThat(loginResponseBean.getJwtToken()!=null).isTrue();
catch(Exception e)
异常的堆栈跟踪：

我该怎么办？
【问题讨论】：
您需要提供更多信息，能否展示完整的测试类 @Deadpool 更新了完整课程的问题。 你只在测试期间得到这个异常？如果您使用堆栈跟踪添加异常会很有帮助 @Deadpool 也添加了堆栈跟踪 如果你尝试模拟存储库怎么样？由于这是一个测试，我只是提供想法 【参考方案1】：在您的 postgreSQL 控制台中运行此查询：
如果“uuid-ossp”不存在则创建扩展；
【讨论】：
以上是关于无法在 Spring Boot 测试中加载类 [pg-uuid]的主要内容，如果未能解决你的问题，请参考以下文章
如何在 spring-boot 配置中加载 application.yaml 配置以进行硒测试
如何在 Spring Boot 测试中加载仅添加命名组件的基本 Spring Application-Context？
