Spring 声明式事务管理----基于TransactionProxyFactoryBean的方式

 使用案例代码:

  #数据模型层

package com.sunline.entity;/** * Account entity. @author MyEclipse Persistence Tools */public class Account  implements java.io.Serializable {    // Fields         private Integer id;     private String name;     private Double money;    // Constructors    /** default constructor */    public Account() {    }/** minimal constructor */    public Account(String name) {        this.name = name;    }        /** full constructor */    public Account(String name, Double money) {        this.name = name;        this.money = money;    }       // Property accessors    public Integer getId() {        return this.id;    }        public void setId(Integer id) {        this.id = id;    }    public String getName() {        return this.name;    }        public void setName(String name) {        this.name = name;    }    public Double getMoney() {        return this.money;    }        public void setMoney(Double money) {        this.money = money;    }   }
