Spring数据jpa-没有定义名为“entityManagerFactory”的bean; 注入自动装载的依赖关系失败
我正在开发应用程序使用spring的数据jpa，hibernate，mysql，tomcat7，maven和它的创build错误。我试图弄清楚，但我失败了。
错误是在设置构造函数参数的时候无法parsingbean的'entityManagerFactory'引用; 没有定义名为“entityManagerFactory”的bean; 注入自动装载的依赖关系失败

RoleRepository是
import org.springframework.data.jpa.repository.JpaRepository; import org.wahid.cse.entity.Role; public interface RoleRepository extends JpaRepository<Role, Integer>{ }
Spring Data JPA默认查找一个名为entityManagerFactory的EntityManagerFactory。 查看EnableJpaRepositories的Javadoc的这一部分或Spring Data JPA 文档的 Table 2.1 。
这意味着你必须重命名你的emf bean到entityManagerFactory或者把你的Springconfiguration改成：
<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" />
（如果你使用的是XML）
要么
@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")
（如果您正在使用Javaconfiguration）
在您的应用程序上下文中，将id从emf改为entityManagerFactory ：
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="packagesToScan" value="org.wahid.cse.entity" /> <property name="dataSource" ref="dataSource" /> <property name="jpaProperties"> <props> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> </props> </property> <property name="persistenceProvider"> <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean> </property> </bean>
至
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="packagesToScan" value="org.wahid.cse.entity" /> <property name="dataSource" ref="dataSource" /> <property name="jpaProperties"> <props> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> </props> </property> <property name="persistenceProvider"> <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean> </property> </bean>
