OrderDao.java

/**
 * 
 */
package com.spring.transactionManager;

import org.springframework.jdbc.core.JdbcTemplate;

/**
 * @author lihai 
 * @createdtime 2018-5-15 下午10:47:47
 * @类描述
 */
public class OrderDao {
	private JdbcTemplate jdbcTemplate;
	/**
	 * @param jdbcTemplate the jdbcTemplate to set
	 */
	public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
		this.jdbcTemplate = jdbcTemplate;
	}
	
	public void lessMoney(){
		String sql="update account set salary=salary-? where name=?";
		jdbcTemplate.update(sql, 500,"小王");
	}
	public void moreMoney(){
		String sql="update account set salary=salary+? where name=?";
		jdbcTemplate.update(sql, 500,"小杰");
	}
}

OrderService.java

/**
 * 
 */
package com.spring.transactionManager;

/**
 * @author lihai 
 * @createdtime 2018-5-15 下午10:48:21
 * @类描述
 */
public class OrderService {
	private OrderDao orderDao;
	/**
	 * @param orderDao the orderDao to set
	 */
	public void setOrderDao(OrderDao orderDao) {
		this.orderDao = orderDao;
	}
	
	public void accountMoney(){
		orderDao.lessMoney();
		
		//int i=10/0;
		int i=10/0;
		
		orderDao.moreMoney();
	}
	
}

TestTransactionManager.java

/**
 * 
 */
package com.spring.transactionManager;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @author lihai 
 * @createdtime 2018-5-15 下午11:02:21
 * @类描述
 */
public class TestTransactionManager {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("transaction-manager.xml");
		OrderService orderService = (OrderService) context.getBean("orderService");
		orderService.accountMoney();
	}

}

在OrderDao.java中注意sql语句的书写和update中的参数顺序。
