Spring Boot错误没有类型为'javax.persistence.EntityManagerFactory'的合格bean

Question

我正在尝试组装一个Spring Boot（2.1.4）REST应用程序。当我尝试在Eclipse中启动应用程序时，遇到以下错误，并且由于过去我做过类似的可行项目而无法确定问题所在：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'claimController': Unsatisfied dependency expressed through field 'claimService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'claimService': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available

***************************
APPLICATION FAILED TO START
***************************

Description:

Field claimService in com.hms.vector.datasink.controller.ClaimController required a bean of type 'javax.persistence.EntityManagerFactory' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

这是我的应用程序类：

@SpringBootApplication
@ComponentScan({ "com.hms.vector.datasink" })
public class DataSinkRestApplication {

    public static void main( String[] args ) {
        SpringApplication.run(DataSinkRestApplication.class, args);
    }

}

这是我的控制人：

@RestController
@EnableAutoConfiguration
public class ClaimController {

    @Autowired
    ClaimService claimService;

    @PostMapping(value = "/inbound/claim/insert", consumes="application/json", produces="application/json")
    public ResponseEntity<HttpStatus> insertClaim(@RequestBody String messageBody) {
        claimService.insertClaim(messageBody);
        return new ResponseEntity<>(HttpStatus.OK);
    }

}

这是服务模块：

@Service
public class ClaimService {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private Environment env;

    @PersistenceContext
    private EntityManager entityManager;

    public void insertClaim(String messageBody) {
        Query query = entityManager.createNativeQuery(env.getProperty("sql.insert.statement"));

        ClaimInput input = parseMessage(messageBody);

        ** set query parameters **

        query.executeUpdate();
    }

}

现在，我只是想让它在Eclipse中本地运行，而没有尝试部署到任何服务器。我对可能丢失的东西一无所知。任何帮助可能会丢失将不胜感激。如果我需要提供其他信息，请告诉我。

Answer 1

尝试将注释@EnableJpaRepositories添加到您的DataSinkRestApplication类中。

您也应该从控制器中删除@EnableAutoConfiguration。如果您不需要专门使用@ComponentScan注释，也是个好主意。

希望有帮助。

Answer 2

删除此

<exclusions>
   <exclusion>
    <groupId>com.zaxxer</groupId>
     <artifactId>HikariCP</artifactId>
       </exclusion>
 </exclusions>

或添加另一个连接池依赖项。
