问题描述
我正在使用spring数据jpa,hibernate,mysql,tomcat7,maven开发应用程序,这就是创建错误。我想弄明白但是我失败了。
I'm developing application using spring data jpa,hibernate,mysql,tomcat7,maven and it's create error.I'm trying to figure it out but i failed.
错误是在设置构造函数参数时无法解析对beanentityManagerFactory的引用;没有定义名为'entityManagerFactory'的bean;注入自动连接的依赖项失败

RoleRepository是
RoleRepository is
import org.springframework.data.jpa.repository.JpaRepository;
import org.wahid.cse.entity.Role;
public interface RoleRepository extends JpaRepository<Role, Integer>{
}
推荐答案
Spring Data JPA默认查找名为 entityManagerFactory
的EntityManagerFactory。查看部分Javadoc EnableJpaRepositories
或表2.1
Spring Data JPA 。
Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory
. Check out this part of the Javadoc of EnableJpaRepositories
or Table 2.1
of the Spring Data JPA documentation.
这意味着您必须将 emf
bean重命名为 entityManagerFactory
或将您的Spring配置更改为:
That means that you either have to rename your emf
bean to entityManagerFactory
or change your Spring configuration to:
<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" />
(如果您使用的是XML)
(if you are using XML)
或
@EnableJpaRepositories(basePackages =your.package,entityManagerFactoryRef =emf)
(如果您使用的是Java Config)
(if you are using Java Config)
