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();
		
	}

		}

	}

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);
	}
}

用服务接口的怎么办?

抛出异常了还怎么获得返回值呢
