我正在开发一个
spring mvc项目,我想转换我在我的applicationContext.xml中的jpa配置,这是我在spring mvc 3上工作时写的,现在我想转到spring Mvc 4并写下我所有的Jpa只使用
Java注释的配置可以有人帮助我
这是我的applicationContext文件:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.MysqL.jdbc.Driver"></property> <property name="url" value="jdbc:MysqL://localhost:3306/db_adpub"></property> <property name="username" value="root"></property> <property name="password" value=""></property> </bean> <bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager"> <property name="persistenceXmlLocations"> <list> <value>classpath*:meta-inf/persistence.xml</value> </list> </property> <property name="defaultDataSource" ref="datasource"></property> </bean> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerfactorybean"> <property name="persistenceUnitManager" ref="persistenceUnitManager"></property> <property name="persistenceUnitName" value="adpub"></property> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"></property> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> <context:annotation-config></context:annotation-config> <mvc:annotation-driven /> </beans>
Merci d’avance
解决方法
您必须按如下方式创建spring bean组件(或bean):
@Compnonent MyTransactionManager { @Autowired EntityManagerFactory entityManagerFactory; ...Constructor to set properties and entityManagerFactory ...Getters and setters } @Component entityManagerFactory{ persistenceUnitName @Autowired PersistenceUnitManager persistenceUnitManager ...Constructor to set properties and persistenceUnitManager ...Getters and setters } @Component persistenceUnitManager{ Values as described in properties file,for example like public @Value("${version}") String version; ...Constructor to set properties ...Getters and setters }
