1.1原始方式整合
11.编写相应配置文件
·Spring配置文件:applicationContext..xml
·SprngMVCi配置文件:spring-mvc.xml
·MyBatis映射文件:AccountMapper..xml
.MyBatis核心文件:sqlMapConfig.xml
数据库连接信息文件:idbc.properties
·Web.xml文件:web.xml
·日志文件:log4ixml
项目前置准备(通用)

1.2Spring整合Mybatis
整合思路
1.只需改变AccountServieImpl 把Session工厂交给Spring容器管理
2.事务的控制交给Spring容器进行声明式事务控制
AccountServieImpl
package com.itheima.service.impl;
import com.itheima.domain.Account;
import com.itheima.mapper.AccountMapper;
import com.itheima.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Autowired
private AccountMapper accountMapper;
@Override
public void save(Account account) {
accountMapper.save(account);
}
@Override
public List<Account> findAll() {
return accountMapper.findAll();
}
}
·Spring配置文件:applicationContext.xml
mybatis配置数据库 扫描包交给spring
