mybatis集成spring的事务管理

原文地址http://lyl290932857.iteye.com/blog/1423800

第一 创建一个测试实体 
Java代码  收藏代码
public class Order {  
  
    private int id;  
    private String orderName;  
      
    public Order(String orderName) {  
        this.orderName = orderName;  
    }  
      
    public int getId() {  
        return id;  
    }  
    public void setId(int id) {  
        this.id = id;  
    }  
    public String getOrderName() {  
        return orderName;  
    }  
    public void setOrderName(String orderName) {  
        this.orderName = orderName;  
    }  
}  


第二 创建映射器以及对应的xml 

只是做了一个简单的订单映射 
Java代码  收藏代码
public interface OrderMapper {  
  
    void insertOrder(Order order);  
}  


Xml代码  收藏代码
<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"   
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">  
  
<mapper namespace="com.sagaware.mapper.OrderMapper">  
<!-- 开启缓存 -->  
  <cache />  
  <insert id="insertOrder" parameterType="Order" keyProperty="id"        useGeneratedKeys="true">  
    insert into tb_order(name) values (#{orderName})   
  </insert>  
</mapper>  



第三步 写一个service类 

Java代码  收藏代码
@Service("orderService")  
public class OrderService {  
  
    @Autowired  
    private OrderMapper mapper;  
      
    /** 
     * 事务处理必需抛出异常 spring 才会帮事务回滚 
     * @param orders 
     */  
    @Transactional  
    public void insertOrder(List<Order> orders) {  
        for(int i = 0 ; i < orders.size() ; i++) {  
            if(i < 2) {  
                mapper.insertOrder(orders.get(i));  
            } else {  
                throw new RuntimeException();  
        <pre name="code" class="java"></pre>    }  
<br>        }  
<br>    }  
<br>  


第四部 也就是重点，配置spring配置文件 

Xml代码  收藏代码
<?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:aop="http://www.springframework.org/schema/aop"  
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"  
    xmlns:context="http://www.springframework.org/schema/context"  
    xsi:schemaLocation="  
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd  
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
     http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd  
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd  
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">  
  
    <!-- 数据源 -->  
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">  
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>  
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test"></property>  
        <property name="user" value="root"></property>  
        <property name="password" value="root"></property>  
    </bean>  
  
    <!-- 开启注解配置 -->  
    <context:annotation-config />  
  
    <!-- 扫描service层 -->  
    <context:component-scan base-package="com.sagaware.service" />  
  
    <!-- 开启事务注解驱动 -->  
    <tx:annotation-driven />  
  
    <!-- 事务管理器 -->  
    <bean id="transactionManager"  
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource" />  
    </bean>  
  
    <!-- 创建SqlSessionFactory -->  
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
        <property name="typeAliasesPackage" value="com.sagaware.entity" />  
    </bean>  
  
    <!-- 自动扫描映射器 -->  
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
        <property name="basePackage" value="com.sagaware.mapper" />  
    </bean>  
</beans>  


最后 写一个测试类 

Java代码  收藏代码
public class Main {  
  
    public static void main(String[] args) {  
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");  
        OrderService service = (OrderService) context.getBean("orderService");  
        System.out.println(service);  
        List<Order> orders = new ArrayList<Order>();  
        for(int i = 0 ; i < 5 ; i++) {  
            Order order = new Order("订单" + i);  
            orders.add(order);  
        }  
        service.insertOrder(orders);  
    }  
}
