mybatis集成spring的事务管理

第一 创建一个测试实体

 1 public class Order {
 2 
 3     private int id;
 4     private String orderName;
 5     
 6     public Order(String orderName) {
 7         this.orderName = orderName;
 8     }
 9     
10     public int getId() {
11         return id;
12     }
13     public void setId(int id) {
14         this.id = id;
15     }
16     public String getOrderName() {
17         return orderName;
18     }
19     public void setOrderName(String orderName) {
20         this.orderName = orderName;
21     }
22 }

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 

1 public interface OrderMapper {
2 
3     void insertOrder(Order order);
4 }
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
 3 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 4 
 5 <mapper namespace="com.sagaware.mapper.OrderMapper">
 6 <!-- 开启缓存 -->
 7   <cache />
 8   <insert id="insertOrder" parameterType="Order" keyProperty="id"        useGeneratedKeys="true">
 9       insert into tb_order(name) values (#{orderName}) 
10   </insert>
11 </mapper>

第三步 写一个service类 

 

 1 @Service("orderService")
 2 public class OrderService {
 3 
 4     @Autowired
 5     private OrderMapper mapper;
 6     
 7     /**
 8      * 事务处理必需抛出异常 spring 才会帮事务回滚
 9      * @param orders
10      */
11     @Transactional
12     public void insertOrder(List<Order> orders) {
13         for(int i = 0 ; i < orders.size() ; i++) {
14             if(i < 2) {
15                 mapper.insertOrder(orders.get(i));
16             } else {
17                 throw new RuntimeException();
18         <pre name="code" class="java"></pre>    }
19 <br>        }
20 <br>    }
21 <br>

第四部 也就是重点，配置spring配置文件 

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
 4     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 5     xmlns:context="http://www.springframework.org/schema/context"
 6     xsi:schemaLocation="
 7      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
 8      http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
 9      http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
10      http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
11      http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
12 
13     <!-- 数据源 -->
14     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
15         <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
16         <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test"></property>
17         <property name="user" value="root"></property>
18         <property name="password" value="root"></property>
19     </bean>
20 
21     <!-- 开启注解配置 -->
22     <context:annotation-config />
23 
24     <!-- 扫描service层 -->
25     <context:component-scan base-package="com.sagaware.service" />
26 
27     <!-- 开启事务注解驱动 -->
28     <tx:annotation-driven />
29 
30     <!-- 事务管理器 -->
31     <bean id="transactionManager"
32         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
33         <property name="dataSource" ref="dataSource" />
34     </bean>
35 
36     <!-- 创建SqlSessionFactory -->
37     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
38         <property name="dataSource" ref="dataSource" />
39         <property name="typeAliasesPackage" value="com.sagaware.entity" />
40     </bean>
41 
42     <!-- 自动扫描映射器 -->
43     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
44         <property name="basePackage" value="com.sagaware.mapper" />
45     </bean>
46 </beans>

最后 写一个测试类

 1 public class Main {
 2 
 3     public static void main(String[] args) {
 4         ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
 5         OrderService service = (OrderService) context.getBean("orderService");
 6         System.out.println(service);
 7         List<Order> orders = new ArrayList<Order>();
 8         for(int i = 0 ; i < 5 ; i++) {
 9             Order order = new Order("订单" + i);
10             orders.add(order);
11         }
12         service.insertOrder(orders);
13     }
14 }
