我正在将技术堆栈从Spring 3升级到Spring 4,将Hibernate 3升级到HIbernate 4。 当前,我们正在使用Hibernate3Support和模板,现在我们转向实体管理器。 所有的数据库条目都在hbm.xml中,如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.mycompany.Employee" table="employee">
<id column="employeeid" name="employeeID">
<generator class="assigned"/>
</id>
<property name="name" type="string">
<column length="100" name="name"/>
</property>
<many-to-one class="com.mycompany.Department" name="department"/>
</class>
</hibernate-mapping>
配置如下:
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="myDataSource"/>
</property>
<property name="mappingLocations">
<value>classpath*:com/**/*.hbm.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">com.mycompany.ExMySQLInnoDBDialect</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
现在,我们希望将系统与要在注释中创建的新实体一起使用,并且我们需要支持hbm.xml文件,因为我们有很多文件并且无法手动转换它们。 新配置:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="packagesToScan" value="com.mycompany"/>
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>
<property name="persistenceUnitPostProcessors">
<list>
<bean
class="org.springframework.data.jpa.support.ClasspathScanningPersistenceUnitPostProcessor">
<constructor-arg index="0" value="com.mycompany" />
<property name="mappingFileNamePattern" value="classpath*:com/**/*hbm.xml" />
</bean>
</list>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
当我运行应用程序然后获取该实体的映射异常时,请让我知道该怎么做。
答案 0 :(得分:0)
得到代码中的问题,该行应为:
<property name="mappingFileNamePattern" value="**/*hbm.xml" />
