IllegalArgumentException: Unknown entity

需要使用persistence.xml进行配置。

 1 <?xml version="1.0" encoding="UTF-8"?> 2 <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> 3   <persistence-unit name="WebofficeOne" transaction-type="RESOURCE_LOCAL"> 4     <provider>org.hibernate.ejb.HibernatePersistence</provider> 5 <!--     <jta-data-source>dataSource</jta-data-source> --> 6     <class>net.etec.ftm.domain.City</class> 7     <class>net.etec.ftm.domain.Country</class> 8     <exclude-unlisted-classes>false</exclude-unlisted-classes> 9     <properties>10         <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />11         <property name="hibernate.show_sql" value="true"/>12         <property name="hibernate.hbm2ddl.auto" value="update"/>13         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>14         <property name="hibernate.connection.username" value="root"/>15         <property name="hibernate.connection.password" value="801216"/>16         <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/test?createDatabaseIfNotExist=true"/>17         <property name="hibernate.c3p0.min_size" value="5"/>18         <property name="hibernate.c3p0.max_size" value="20"/>19         <property name="hibernate.c3p0.timeout" value="300"/>20         <property name="hibernate.c3p0.max_statements" value="50"/>21         <property name="hibernate.c3p0.idle_test_period" value="3000"/>22     </properties>23   </persistence-unit>24 </persistence>

 

实体工厂配置

 1     <bean id="entityManagerFactory" 2         class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 3         <property name="persistenceUnitName" value="WebofficeOne" /> 4 <!--         <property name="dataSource" ref="dataSource" /> --> 5         <property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" /> 6 <!--         <property name="packagesToScan" value="http://www.mamicode.com/com.etec.ftm.domain" /> --> 7         <property name="persistenceXmlLocation" value="classpath:META-INF/persistence-instance.xml"/> 8         <property name="jpaProperties"> 9             <props>10                 <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>11                 <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>12                 <prop key="hibernate.show_sql">true</prop>13                 <prop key="hibernate.hbm2ddl.auto">create</prop>14             </props>15         </property>16     </bean>
