(C)2015 技术邻 | 浙ICP备号-1 |JPA测试发生Not an managed type，求大神帮忙解决
我这边的思路是有ID虚类，之后由entity继承，注意：在运行的状态下，能够正常工作，但是当我希望使用Spring Test时，给我报错Not an managed type，起先我以为是UUID的问题，到后面发现并不是由UUID引起，普通ID也没有，我这里使用的是自动扫描。配置如下：
&!-- 对JPA声明以hibernate进行实现 --&
&bean id="persistenceProvider" class="org.hibernate.ejb.HibernatePersistence"/&
&bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" /&
&bean id="jpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/&
&!-- JPA进行实体扫描 --&
&bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"&
&!-- 自动扫描Entity实体 --&
&property name="packagesToScan" value="com.hava.demo"/&
&!-- 指明JPA的persistence的配置文件位置 --&
&property name="persistenceXmlLocation" value="/WEB-INF/appconfig/orm/jpa/persistence.xml" /&
&property name="persistenceUnitName" value="persistenceUnit"/&
&!-- 注入dataSource --&
&property name="dataSource" ref="dataSource"/&
&property name="jpaVendorAdapter" ref="jpaVendorAdapter" /&
&!-- 指定具体实现ORM框架的特定属性 --&
&property name="jpaProperties"&
&prop key="hibernate.show_sql"&true&/prop&
&prop key="hibernate.hbm2ddl.auto"&update&/prop&
&prop key="hibernate.dialect"&${jdbc.dialect}&/prop&
&/property&
&bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"&
&property name="entityManagerFactory" ref="entityManagerFactory"/&
&!--说明事务的配置使用的注解方式--&
&tx:annotation-driven transaction-manager="transactionManager"/&
&!-- Spring Data Jpa自动扫描Repository进行DAO实现--&
&jpa:repositories base-package="com.hava.demo" /&
