SSM整合案例（超详细）
- 环境准备
- 整合步骤
环境准备
前提须知
在SSM整合的时候，我们是用Spring框架去整合SpringMVC框架和MyBatis框架。
创建数据库和表结构
create database ssm;
create table account(
id int primary key auto_increment,
name varchar(100),
money double(7,2)
);
创建 Maven 工程 ssm
目录结构：
导入坐标并建立依赖
MyBatis 和 Spring 的版本对应关系

编写实体类
Account：
package com.keafmd.domain;
import java.io.Serializable;
/**
* Keafmd
*
* @ClassName: Account
* @Description: 账户实体类
* @author: 牛哄哄的柯南
* @date: 2021-02-17 21:03
*/
public class Account implements Serializable
private Integer id;
private String name;
private Double money;
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;
@Override
public String toString()
return "Account" +
"id=" + id +
", name='" + name + '\\'' +
", money=" + money +
'';
编写持久层接口
package com.keafmd.dao;
import com.keafmd.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* Keafmd
*
* @ClassName: AccountDao
* @Description: 账户dao接口
* @author: 牛哄哄的柯南
* @date: 2021-02-17 21:05
*/
public interface AccountDao
//查询所有账户
public List<Account> findAll();
//保存账户
public void saveAccount(Account account);
编写业务层接口
package com.keafmd.service;
import com.keafmd.domain.Account;
import java.util.List;
/**
* Keafmd
*
* @ClassName: AccountService
* @Description:
* @author: 牛哄哄的柯南
* @date: 2021-02-17 21:15
*/
public interface AccountService
//查询所有账户
public List<Account> findAll();
//保存账户
public void saveAccount(Account account);
编写业务层实现类
package com.keafmd.service.impl;
import com.keafmd.dao.AccountDao;
import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Keafmd
*
* @ClassName: AccountServiceImpl
* @Description: 账户的业务层实现类
* @author: 牛哄哄的柯南
* @date: 2021-02-17 21:16
*/
public class AccountServiceImpl implements AccountService
@Override
public List<Account> findAll()
System.out.println("业务层，查询所有。。。");
return null;
@Override
public void saveAccount(Account account)
System.out.println("业务层，保存账户。。。");
编写 Controller
package com.keafmd.controller;
/**
* Keafmd
*
* @ClassName: AccountController
* @Description: 账户控制器 web
* @author: 牛哄哄的柯南
* @date: 2021-02-17 21:19
*/
public class AccountController
整合步骤
保证 Spring 框架在 web 工程中独立运行
第一步：编写 spring 配置文件并导入约束
applicationContext.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
