mybatis集成spring的事务管理

第一 创建一个测试实体

 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

 public interface OrderMapper {

     void insertOrder(Order order);
 }

 <?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

 @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 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

 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);
     }
 }
