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);
    }
}
