Hibernate4+Spring3+SpringMVC事务管理

一，Hibernate4配置

dataSource.password=111111

dataSource.username=root
dataSource.databaseName=goodsmanage
dataSource.driverClassName=com.mysql.jdbc.Driver

dataSource.dialect=org.hibernate.dialect.MySQL5Dialect
dataSource.serverName=localhost:3306
dataSource.url=jdbc:mysql://localhost:3306/goodsmanage
dataSource.properties=user=${dataSource.username};databaseName=${dataSource.databaseName};serverName=${dataSource.serverName};password=${dataSource.password}
dataSource.hbm2ddl.auto=update
dataSource.show_sql=true

hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
hibernate.hbm2ddl.auto=none
hibernate.show_sql=false
hibernate.query.substitutions=true 1, false 0
hibernate.default_batch_fetch_size=16
hibernate.max_fetch_depth=2
hibernate.bytecode.use_reflection_optimizer=true
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=true
hibernate.cache.region.factory_class=org.hibernate.cache.EhCacheRegionFactory
net.sf.ehcache.configurationResourceName=/ehcache_hibernate.xml
hibernate.cache.use_structured_entries=true
hibernate.generate_statistics=true

proxool.maximum.connection.count=40
proxool.minimum.connection.count=5
proxool.statistics=1m,15m,1h,1d
proxool.simultaneous.build.throttle=30,

<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>

2，Spring3声明事务管理

<!-- 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/**"
4000
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

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
