找不到Spring Boot 2.1 EntityManagerFactory Bean

Question

我有一个使用JPA、Web和PostgreSQL的简单Spring Boot项目。我使用的是最新的Spring Boot版本2.1.3。

APPLICATION FAILED TO START

Description:

Field dataMappingRepository in com.my.example.service.impl.SimpleServiceImpl required a bean named 'entityManagerFactory' that could not be found.

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


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

public class SimpleServiceImpl implements SimpleService {
  @Autowired private SimpleJpaRepository repo;
}

public interface SimpleJpaRepository extends JpaRepository<SimpleEntity, Long> {}

spring:
   datasource:
      url: jdbc:postgresql://localhost:5432/simple
      username: user
      password: pass
      driver-class-name: org.postgresql.Driver
   jpa:
      show-sql: false
      properties:
         hibernate:
            dialect: org.hibernate.dialect.PostgreSQLDialect
      hibernate:
         ddl-auto: validate

Answer 1

好的，最后问题就像Andy Wilkinson在缓存Hibernate依赖项中所说的那样。

从我的M2回购中删除org.hibernate文件夹并更新maven项目后，它工作正常。
