详解spring+springmvc+mybatis整合注解

每天记录一点点，慢慢的成长，今天我们学习了ssm，这是我自己总结的笔记，大神勿喷！谢谢，主要代码！！ !

spring&springmvc&mybatis整合（注解）

1.jar包

2.引入web.xml文件

contextConfigLocation

classpath:applicationContext.xml

org.springframework.web.context.ContextLoaderListener

springmvc

org.springframework.web.servlet.DispatcherServlet

<init-param>

contextConfigLocation

classpath:springmvc.xml

springmvc

*.action

3.创建实体类

4.引入一个（类名）dao.xml

update accounting set money=#{money} where name=#{name}

select * from accounting where name=#{name}

5.创建一个（类名）dao

public void update(Accounting a);

public Accounting findMoneyByName(String name);

6.写service

public void remit(String from,String to,double money);

7.写serviceimpl

@Service

public class AccountServiceImpl implements AccountService {

@Autowired

private AccountDao ad;

@Override

public void remit(String from, String to, double money) {

Accounting fromAccount=ad.findMoneyByName(from);

fromAccount.setMoney(fromAccount.getMoney()-money);

ad.update(fromAccount);

Accounting toAccount=ad.findMoneyByName(to);

toAccount.setMoney(toAccount.getMoney()+money);

ad.update(toAccount);

}

}

8.引入applicationContext.xml

destroy-method="close">

destroy-method="close">

9.引入db.properties文件和log4j.properties文件

10.引入springmvc.xml文件

xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:mvc="http://springframework.org/schema/mvc"

xmlns:context="http://springframework.org/schema/context"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"
