(二)在一的基础上集成spring 4.0.3 并整合JPA以及spring的单元测试
1）加上sping的依赖包，并在base模块进行引用。
<!-- spring包依赖-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>
</dependency>
2）创建spring_base.xml，在spring配置文件中整合jpa
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<!-- 1
1)开启注解自动配置组件的自动扫描 (@Component是所有受Spring管理组件的通用形式)
@Repository、@Service和 @Controller则是@Component的细化，
用来表示更具体的用例(例如，分别对应了持久化层、服务层和表现层)
2)把use-default-filters属性設為false，意即在base-package所有被宣告為@Component和@Configuration等target Class
不予註冊為bean，由filter子標籤代勞。
Use-dafault-filters=”false”的情况下： <context:exclude-filter>指定的不扫描，
<context:include-filter>指定的扫描
-->
<context:component-scan base-package="org.smd" use-default-filters="true">
<!-- 只扫描Repository标注的类 -->
<!-- <context:include-filter type="annotation" expression="org.springframework.stereotype.Service" />
<context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" /> -->
</context:component-scan>
<!--2配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 配置连接池的初始值 -->
<property name="initialSize" value="${initialSize}" />
<!-- 连接池的最大值 -->
<!-- <property name="maxActive" value="500"/> -->
<!-- 最大空闲时，当经过一个高峰之后，连接池可以将一些用不到的连接释放，一直减少到maxIdle为止 -->
<!-- <property name="maxIdle" value="2"/> -->
<!-- 当最小空闲时，当连接少于minIdle时会自动去申请一些连接 -->
<property name="minIdle" value="${minIdle}" />
<property name="maxActive" value="${maxActive}" />
<property name="maxIdle" value="${maxIdle}" />
<property name="maxWait" value="${maxWait}" />
</bean>
<context:property-placeholder location="classpath:jdbc.properties" />
<!--3 Spring整合jpa -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
</bean>
<!--4 事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<!--5 采用注释的方式管理事务-->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
3）在base模块创建 dao包，service等包，因为现在是集成阶段，具体搭建，等整合结束，再接着搭建
4）创建操作POJO类 的 productType的服务类ProductServiceImpl
public interface IProductService extends ICommonService {
/*****
* 保存productType
* @param productType
*/
public abstract void saveProductType(ProductType productType);
}
@Service
@Transactional
public class ProductServiceImpl implements IProductService {
@PersistenceContext
EntityManager entityManager;
/* (non-Javadoc)
* @see org.smd.base.service.IProductService#saveProductType(org.smd.base.model.ProductType)
*/
public void saveProductType(ProductType productType){
entityManager.persist(productType);
}
}
import org.junit.Test;
import org.junit.runner.RunWith;
import org.smd.base.model.ProductType;
import org.smd.base.service.IProductService;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring_base.xml")
public class ProductTypeSpringTest {
@Inject
IProductService productService;
@Test
public void Test01(){
ProductType productType=new ProductType();
productType.setName("aa");
productService.saveProductType(productType);
}
}
运行单元测试，spring整合jpa，成功
