典型的Spring的applicationcontext.xml配置文件以及注解事物配置（转）

 注解配置事务：

 

 <!-- 启动注入功能 -->>    <context:annotation-config />    <!-- 启动扫描component功能 -->    <context:component-scan base-package="org.mybatis.jpetstore" />    <!-- 启动注解实物配置功能 -->    <tx:annotation-driven transaction-manager="transactionManager" /><!-- 数据源 --><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>        <property name="url" value="jdbc:mysql://localhost:3306/test"></property>        <property name="username" value="root"></property>        <property name="password" value="root"></property>    </bean><!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>

 

 然后再需要配置的地方加上类似于这样的格式即可：

 

  @Transactional(propagation=Propagation.REQUIRED,rollbackFor=Exception.class)  public void userTest() throws Exception {  User u1 = new User();  u1.setUsername("service 添加");  userMapper.insert(u1);  System.out.println("service 添加");  String s = null;  if(s == null){  throw new Exception("自定义异常");  }  u1 = new User();  u1.setUserId(4);  u1.setUsername("service 修改");  userMapper.update(u1);  System.out.println("service 修改");  }

 

 

spring注解式事务管理实例

 

一.spring配置文件

这里使用spring命名空间，如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-2.5.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"
    default-autowire="byName"  default-lazy-init="true">

 

 <context:property-placeholder location="classpath:jdbc.properties" />

 <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}" />
  <property name="initialSize" value="${jdbc.initialSize}" />
  <property name="maxActive" value="${jdbc.maxActive}" />
  <property name="maxIdle" value="${jdbc.maxIdle}" />
  <property name="minIdle" value="${jdbc.minIdle}" />
  <property name="maxWait" value="${jdbc.maxWait}" />
 </bean>

 <!-- 设定transactionManager -->
 <bean id="transactionManager"
  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  <property name="dataSource" ref="dataSource" />
 </bean>

<!--启动spring注解功能-->

 <tx:annotation-driven transaction-manager="transactionManager" />

 
</beans>

 

说明： 

1.如果事务管理器的id是transactionManager，这里可以不对transaction-manager进行配置，即<tx:annotation-driven />就可以。

2.这个配置是告诉spring在类（接口）层面或者方法层面上检查应用程序上下文中的所有标准了@Transactional的bean，spring将自动把事务通知的内容通知给它。

3.这个通知的事务参数将由@Transactional注释的参数来定义。

4.如果注释的是接口，则该接口的所有实现类都将被事务化。

 

二.使用@Transactional标注bean

 

 @Transactional(propagation=Propagation.REQUIRED,rollbackFor=Exception.class)
 public void method(){}  

 

记得要将这个bean加入到spring上下文中。

 

一般来说，上述两种事务策略就可以满足要求了，不过需要注意，注解功能的使用需要在项目中加入cglib-nodep-x.x_x.jar
