Spring Hibernate事务配置总结
一、TransactionProxyFactoryBean声明式事务配置
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<!-- 事务代理、所有Bean共享一个代理基类-->
<bean id="transactionBase" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transactionManager"></property>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<!-- 指定目标业务Bean -->
<bean id="tempService" parent="transactionBase" >
<property name="target" ref="tempServiceTarget" />
</bean>
<bean id="tempServiceTarget"
class="com.cj.transaction.service.TempService" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userDAO">
<ref bean="userDAO" />
</property>
<property name="deptDAO">
<ref bean="deptDAO" />
</property>
</bean>
二、 基于tx/aop声明式事务配置一、引入aop/tx命名空间
<beans
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: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/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.0.xsd ">
二、基于tx/aop配置
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<!-- 通过aop定义事务增强切面 -->
<aop:config>
<aop:pointcut id="serviceMethod" expression="execution(* com.cj.transaction.service.*.*(..))"/>
<aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice"/>
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="false"/>
<tx:method name="add*" rollback-for="Exception"/>
</tx:attributes>
</tx:advice>
expression="execution(* com.cj.transaction.service.*.*(..))" 中几个通配符的含义：
第一个 * —— 通配 任意返回值类型
第二个 * —— 通配 包com.cj.transaction.service下的任意class
第三个 * —— 通配 包com.cj.transaction.service下的任意class的任意方法
第四个 .. —— 通配 方法可以有0个或多个参数
注意：第一个*后面有一个空格
三、 编程式事务一、使用PlatformTransactionManager
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="txDefinition" class="org.springframework.transaction.support.DefaultTransactionDefinition">
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"></property>
</bean>
public class TempService {
private UserDAO userDAO;
private DeptDAO deptDAO;
private TransactionDefinition txDefinition;
private PlatformTransactionManager txManager;
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public void setDeptDAO(DeptDAO deptDAO) {
this.deptDAO = deptDAO;
}
public void setTxDefinition(TransactionDefinition txDefinition) {
this.txDefinition = txDefinition;
}
public void setTxManager(PlatformTransactionManager txManager) {
this.txManager = txManager;
}
public void addTemp(){
TransactionStatus status = txManager.getTransaction(txDefinition);//
try {
User user = new User();
Dept dept = new Dept();
user.setRemark("USERREMARK");
dept.setRemark("DEPT REMARK");
userDAO.save(user);
deptDAO.save(dept);
txManager.commit(status);//提交事務
} catch (Exception e) {
txManager.rollback(status);
e.printStackTrace();
}
}
}
二、使用TransactionTemplate
<bean id="txTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref="transactionManager"></property>
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"></property>
</bean>
public class Temp1Service {
private UserDAO userDAO;
private DeptDAO deptDAO;
TransactionTemplate txTemplate;
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public void setDeptDAO(DeptDAO deptDAO) {
this.deptDAO = deptDAO;
}
public void setTxTemplate(TransactionTemplate txTemplate) {
this.txTemplate = txTemplate;
}
public void addTemp(){
txTemplate.execute(new TransactionCallback(){
public Object doInTransaction(TransactionStatus status){
try {
User user = new User();
Dept dept = new Dept();
user.setRemark("USERREMARK");
dept.setRemark("DEPT REMARK");
userDAO.save(user);
deptDAO.save(dept);
} catch (Exception e) {
status.setRollbackOnly();//
e.printStackTrace();
return false;
}
return true;
}
});
}
}
