篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Java之SSM框架整合-案例IDEA版（一篇文章精通系列）Spring+SpringMVC+MyBatis（整合源代码）相关的知识，希望对你有一定的参考价值。
Spring+SpringMVC+MyBatis
一、原生整合方式
1、创建数据库表
create database ssmtest;
CREATE TABLE `account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(100) NOT NULL,
`money` double(50,0) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2、创建Maven工程
删除一些没有用的文件以及将缺少的文件创建出来
清空web.xml留下这些即可
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
</web-app>
创建目录结构
3、导入Maven坐标
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

4、编写实体类
package cn.itbluebox.domain;
public class Account {
private int id;
private String name;
private double money;
public Account() {
}
public Account(int id, String name, double money) {
this.id = id;
this.name = name;
this.money = money;
}
public int getId() {
return id;
}
public void setId(int 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;
}
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\\'' +
", money=" + money +
'}';
}
}
5、编写Mapper接口
package cn.itbluebox.mapper;
import cn.itbluebox.domain.Account;
import java.util.List;
public interface AccountMapper {
//保存账号数据
void save(Account account);
//查询账号数据
List<Account> findAll();
}
6、编写MyBatisUtils工具类
package cn.itbluebox.utils;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import java.io.IOException;
import java.io.InputStream;
public class MyBatisUtils {
private static SqlSessionFactory sqlSessionFactory;
static {
InputStream is = null;
try {
is = Resources.getResourceAsStream("SqlMapConfig.xml");
sqlSessionFactory = new SqlSessionFactoryBuilder().build(is);
} catch (IOException e) {
e.printStackTrace();
} finally {
if (is != null) {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
/**
* 获得SqlSession
*/
public static SqlSession openSqlSession() throws IOException {
return sqlSessionFactory.openSession();
}
/**
* 提交释放资源
*/
public static void commitAndClose(SqlSession sqlSession) {
if (sqlSession != null) {
sqlSession.commit();
sqlSession.close();
}
}
/**
* 回滚释放资源
*/
public static void rollbackAndClose(SqlSession sqlSession) {
if (sqlSession != null) {
sqlSession.rollback();
sqlSession.close();
}
}
}
7、 编写Service接口
package cn.itbluebox.service;
import cn.itbluebox.domain.Account;
import java.util.List;
public interface AccountService {
//保存账号数据
void save(Account account);
//查询账号数据
List<Account> findAll();
}
8、编写Service接口实现
package cn.itbluebox.service.impl;
import cn.itbluebox.domain.Account;
import cn.itbluebox.mapper.AccountMapper;
import cn.itbluebox.service.AccountService;
import cn.itbluebox.utils.MyBatisUtils;
import org.apache.ibatis.session.SqlSession;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Override
public void save(Account account) {
SqlSession sqlSession = MyBatisUtils.openSqlSession();
AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
accountMapper.save(account);
sqlSession.commit();
sqlSession.close();
}
@Override
public List<Account> findAll() {
SqlSession sqlSession = MyBatisUtils.openSqlSession();
AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
return accountMapper.findAll();
}
}
9、编写Controller
package cn.itbluebox.controller;
import cn.itbluebox.domain.Account;
