JavaWeb_(Spring框架)整合Mybatis加入事务操作数据库
整合Mybatis
a)导包:
i.Spring:基本包、aop、aspects、jdbc、tx、test;
ii.Mybatis:mybatis-3.4.6
iii.整合包:mybatis-spring-1.3.2
iv.三方包:
1.aopalliance
2.aspectj.weaver
3.c3p0-0.9.5.2
4.mchange-commons-java-0.2.11
5.mysql-connector-java-5.1.46-bin
6.ojdbc7
b)创建项目结构(package):bean、service、mapper、test;
c)创建配置文件:sqlMapperConfig、applicaitonContext
2、创建测试用例:使用Mapper扫描开发,转账;
3、在service中加入事务:利用Spring-aop事务解决转账异常问题;
未添加事务前

package com.Gary.bean;
public class Account {
private Integer id;
private String name;
private Double money;
//转账金额
private Double tranferMoney;
public Double getTranferMoney() {
return tranferMoney;
}
public void setTranferMoney(Double tranferMoney) {
this.tranferMoney = tranferMoney;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
}
Account.java
