Hibernate4+Spring3+SpringMVC事务管理

一，Hibernate4配置

1，首先将hibernate配置信息抽到hibernate.properties里面

dataSource.password=111111

dataSource.username=rootdataSource.databaseName=goodsmanagedataSource.driverClassName=com.mysql.jdbc.DriverdataSource.dialect=org.hibernate.dialect.MySQL5DialectdataSource.serverName=localhost:3306dataSource.url=jdbc:mysql://localhost:3306/goodsmanagedataSource.properties=user=${dataSource.username};databaseName=${dataSource.databaseName};serverName=${dataSource.serverName};password=${dataSource.password}dataSource.hbm2ddl.auto=updatedataSource.show_sql=truehibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialecthibernate.hbm2ddl.auto=nonehibernate.show_sql=falsehibernate.query.substitutions=true 1, false 0hibernate.default_batch_fetch_size=16hibernate.max_fetch_depth=2hibernate.bytecode.use_reflection_optimizer=truehibernate.cache.use_second_level_cache=truehibernate.cache.use_query_cache=truehibernate.cache.region.factory_class=org.hibernate.cache.EhCacheRegionFactorynet.sf.ehcache.configurationResourceName=/ehcache_hibernate.xmlhibernate.cache.use_structured_entries=truehibernate.generate_statistics=trueproxool.maximum.connection.count=40proxool.minimum.connection.count=5proxool.statistics=1m,15m,1h,1dproxool.simultaneous.build.throttle=30,

2，hibernate4已经不在支持使用HibernateTemplate模板类，这里需要将hibernate的sessionFactory和dataSource注入到Spring的事务管理器

SpringContext.xml的配置为

<context:property-placeholder location="classpath:/hibernate.properties" /><!-- Hibernate 参数配置 --><bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 自动扫描指定Package中的@Entity Class --><property name="packagesToScan" value="com.geng.goodsmanage" /><property name="hibernateProperties"><props><prop key="hibernate.dialect">${dataSource.dialect}</prop><prop key="hibernate.generate_statistics">true</prop><prop key="hibernate.connection.release_mode">auto</prop><prop key="hibernate.hbm2ddl.auto">${dataSource.hbm2ddl.auto}</prop><prop key="hibernate.show_sql">${dataSource.show_sql}</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.query.substitutions">${hibernate.query.substitutions}</prop><prop key="hibernate.default_batch_fetch_size">${hibernate.default_batch_fetch_size}</prop><prop key="hibernate.max_fetch_depth">${hibernate.max_fetch_depth}</prop><prop key="hibernate.bytecode.use_reflection_optimizer">${hibernate.bytecode.use_reflection_optimizer}</prop><prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop><prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop><prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop><prop key="net.sf.ehcache.configurationResourceName">${net.sf.ehcache.configurationResourceName}</prop><prop key="hibernate.cache.use_structured_entries">${hibernate.cache.use_structured_entries}</prop></props></property></bean><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /><property name="dataSource" ref="dataSource" /></bean><bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="${dataSource.driverClassName}" /><property name="url" value="${dataSource.url}" /><property name="username" value="${dataSource.username}" /><property name="password" value="${dataSource.password}" /></bean>

 

3,Hibernate4默认必须为开启事务，否则 getCurrentSession()获取不到

2，Spring3声明事务管理

声明事务配置变化不大

<!-- 定义AOP拦截器 --><aop:config proxy-target-class="true"><aop:advisor pointcut="execution(* com.geng..*Service.*(..))"advice-ref="txAdvice" /><!-- <aop:advisor pointcut="execution(* org.geng..*DAO.*(..))" advice-ref="txAdvice" /> --></aop:config><!-- 基本事务定义,使用transactionManager作事务管理,默认get*方法的事务为readonly,其余方法按默认设置 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="save*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="add*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="create*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="insert*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="update*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="merge*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="del*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="remove*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="put*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><tx:method name="use*" propagation="REQUIRED" rollback-for="java.lang.Exception"/><!--hibernate4必须配置为开启事务 否则 getCurrentSession()获取不到 --><tx:method name="get*" propagation="REQUIRED" read-only="true" /><tx:method name="count*" propagation="REQUIRED" read-only="true" /><tx:method name="find*" propagation="REQUIRED" read-only="true" /><tx:method name="list*" propagation="REQUIRED" read-only="true" /><tx:method name="*" read-only="true" /></tx:attributes></tx:advice>

总结：编程时需注意业务上的事务范围，如生成订单，他的事务需在一个service方法里面需要先将货物数量减去，做update，然后再在订单表插入订单，如果这两步操作放在两个service方法里面恐怕异常就无法做到同时回滚。

3,SpringMVC主要配置

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:mvc="http://www.springframework.org/schema/mvc"    xsi:schemaLocation="        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.xsd         http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc.xsd        ">       <!-- 会自动注册了validator ConversionService --><mvc:annotation-driven  />        <!-- 防止图片js csss被拦截 -->       <!--  <mvc:default-servlet-handler /> -->        <!-- 对静态资源文件的访问  方案二 （二选一）-->          <mvc:resources mapping="/**" location="/" />   <!--  <mvc:resources mapping="/images/**" location="/images/" cache-period="31556926"/>      <mvc:resources mapping="/js/**" location="/js/" cache-period="31556926"/>      <mvc:resources mapping="/css/**" location="/css/" cache-period="31556926"/>   -->        <context:component-scan base-package="com.geng.goodsmanage">        <context:include-filter type="annotation"expression="org.springframework.stereotype.Controller" /><context:exclude-filter type="annotation"expression="org.springframework.stereotype.Service" />        </context:component-scan>       <!-- 定义首页 -->    <mvc:view-controller path="/" view-name="forward:/login/toLogin/" />                <!-- 视图的前缀和后缀 -->        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/WEB-INF/"></property>        <property name="suffix" value=".jsp"></property>        </bean>        </beans>

4，web.xml
