BeanDefinitionOverrideException、Spring Data JPA和JDBC Bean冲突

Question

public interface UserRepository2 extends CrudRepository<User, Integer> {

}

@Entity
@Table(name = "userstab")
public class User {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String name;

    private String email;

    ...
}

The bean 'userRepository2', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.

Action:
Consider renaming one of the beans or enabling overriding by setting **spring.main.allow-bean-definition-overriding=true**

Invalid bean definition with name 'userRepository2' defined in null: Cannot register bean definition [Root bean: class [org.springframework.data.**jpa**.repository.support.**JpaRepositoryFactoryBean**]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'userRepository2': There is already [Root bean: class [org.springframework.data.**jdbc**.repository.support.**JdbcRepositoryFactoryBean**]; 

为每个存储库/实体选择JPA/JDBC的最佳实践是什么？

PS：发现@enablejdbcrepositories，带有basePackages属性，但我不确定这是否是个好主意

这几乎可以肯定是由于Spring Data JDBC旧版本中的一个固定错误造成的。确保您至少拥有以下spring-data-jdbc版本之一

1.0.12 1.1.1 2.1.0

有关详细信息，请参见DATAJDBC-437。
