Eclipse下Spring+openJPA做EJB3的开发

Spring的版本号为2.0.6
openJPA的版本为0.9.7(其实1.0.0也是一样)
照下面如此,客户端不用装应用服务器开发了.
但如果你的客户端是Eclipse的RCP则和这个配置有一些不同


 

1.项目的Classpath的列表

    <classpathentry kind="lib" path="main/lib/commons-beanutils.jar"/>
    <classpathentry kind="lib" path="main/lib/commons-beanutils-bean-collections.jar"/>
    <classpathentry kind="lib" path="main/lib/commons-beanutils-core.jar"/>
    <classpathentry kind="lib" path="main/lib/commons-collections-3.2.jar"/>
    <classpathentry kind="lib" path="main/lib/commons-lang.jar"/>
    <classpathentry kind="lib" path="main/lib/commons-logging.jar"/>
    <classpathentry kind="lib" path="main/lib/javaee.jar"/>
    <classpathentry kind="lib" path="main/lib/log4j-1.2.14.jar"/>
    <classpathentry kind="lib" path="main/lib/openjpa-0.9.7-incubating.jar"/>
    <classpathentry kind="lib" path="main/lib/serp-1.11.0.jar"/>
    <classpathentry kind="lib" path="test/lib/aspectjrt.jar"/>
    <classpathentry kind="lib" path="test/lib/aspectjweaver.jar"/>
    <classpathentry kind="lib" path="test/lib/cglib-nodep-2.1_3.jar"/>
    <classpathentry kind="lib" path="test/lib/dbunit-2.2.jar"/>
    <classpathentry kind="lib" path="test/lib/ojdbc14.jar"/>
    <classpathentry kind="lib" path="test/lib/postgresql-8.2-506.jdbc3.jar"/>
    <classpathentry kind="lib" path="test/lib/spring.jar"/>


2.BEANS.XML的配置

 

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true"
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
      
    <bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
        lazy-init="false">
        <property name="locations">
            <list>
                <value>jpa.properties</value>
            </list>
        </property>
    </bean>

    <!-- Pitchfork configuration -->
<!--    <bean-->
<!--        class="org.springframework.jee.ejb.config.JeeEjbBeanFactoryPostProcessor" />-->

    <bean
        class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

    <bean id="persistenceUnitManager"
        class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
        <property name="loadTimeWeaver">
            <bean
                class="org.springframework.instrument.classloading.SimpleLoadTimeWeaver" />
        </property>
    </bean>


    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitManager"
            ref="persistenceUnitManager" />
        <property name="persistenceUnitName" value="${persistence.unit.name}" />

        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter" />
        </property>
    </bean>

    <bean id="transactionManager"
        class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory"
            ref="entityManagerFactory" />
    </bean>

    <tx:advice id="methodTransactionAdvice"
        transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*" />
        </tx:attributes>
    </tx:advice>
    <aop:config proxy-target-class="true">
        <aop:pointcut id="serviceMethods"
            expression="execution(public * com.wilesun.test..*Service.*(..))" />
        <aop:advisor pointcut-ref="serviceMethods"
            advice-ref="methodTransactionAdvice" />
    </aop:config>

    <!-- ================================================ -->
    <bean id="com.wilesun.test.IHelloService"
        class="com.wilesun.test.HelloService" />    
 
                             
</beans>


3.persistence_1_0.xsd和orm_1_0.xsd

将这两个文件放到项目的classpath的根位置

4.做测试程序

public class HelloService implements IHelloServiceLocal, IHelloServiceRemote {
   @PersistenceContext
   private EntityManager em;
   
   @Resource
   private SessionContext ctx;
}
将代码实现完,就可以测试了
