Eclipse下Spring+openJPA做EJB3的開發

Spring的版本號為2.0.6
openJPA的版本為0.9.7(其實1.0.0也是一樣)
照下面如此,客戶端不用裝應用服務器開發了.
但如果你的客戶端是Eclipse的RCP則和這個配置有一些不同

1.項目的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">

<list>

<value>jpa.properties</value>

</list>

</property>

</bean>

<bean

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

<bean id="persistenceUnitManager"

class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">

<bean

class="org.springframework.instrument.classloading.SimpleLoadTimeWeaver" />

</property>

</bean>

<bean id="entityManagerFactory"

class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">

<property name="persistenceUnitManager"

ref="persistenceUnitManager" />

<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

將這兩個文件放到項目的classpath的根位置

4.做測試程序

public class HelloService implements IHelloServiceLocal, IHelloServiceRemote {

@PersistenceContext

private EntityManager em;

@Resource

private SessionContext ctx;

}

將代碼實現完,就可以測試了
