spring学习笔记整理(三)-----spring整合hibernate

一、导包：

(1)spring+aop+hibernate

(2)spring-orm

(3)数据源（spring-jdbc、commons-dbcp2、c3p0）

          </plugin>
      </plugins>
  </build>

二、整合配置文件applicationContext-orm.xml

 

(1) 数据源选择

(2) 根据数据源创建SessionFactory（注入BaseDao）

(3) 事务管理器（简化BaseDao/持久层代码）

(4) 启动注解方式事务管理（配置事务注解到业务逻辑层）（其他：AOP配置方式事务）

    <!-- 1.引入公共配置文件 db.properties-->
    <context:property-placeholder location="classpath:db.properties"/>
    <!--2.配置数据源（c3p0）-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${dataSource.driverClassName}"></property>
        <property name="jdbcUrl"      value="${dataSource.url}"></property>
        <property name="user"          value="${dataSource.username}"></property>
        <property name="password"      value="${dataSource.password}"></property>
        <property name="maxPoolSize" value="40"></property>

        <property name="initialPoolSize" value="1"></property>
        <property name="maxIdleTime" value="20"></property> 
    </bean>
    
    <!--3.配置SessionFactory,注入BaseDao-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
　　　　  //注入数据源
        <property name="dataSource" ref="dataSource"/>
　　　　　//注入扫描的实体类的路径
        <property name="packagesToScan" value="com.demo.entity" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect" >${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

            </props>
        </property>
    </bean>
    <!--4.配置事务管理-->
    <bean id="transactionManager"  class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <!--5.注解事务 ：transaction-manager="transactionManager" -->
    <tx:annotation-driven />    
</beans>

三、引入Spring Test 框架

//让测试运行于Spring测试环境
@RunWith(SpringJUnit4ClassRunner.class)
//Spring整合JUnit4测试时，使用注解引入多个配置文件
@ContextConfiguration(locations={
        "classpath:applicationContext-core.xml"
        ,"classpath:applicationContext-orm.xml"
})
public class UserServiceTest
{
    @Autowired
    private IUserService userService;
    @Test
    public void save() {
        User user = new User();
        user.setUserName("Guest");
        user.setPassword("123");
        
        userService.save(user);
    }
}
