ssm全称:Spring+SpringMVC+Mybatis

ssm简介：

1、Spring

Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。

2、SpringMVC

　　 Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。

3、MyBatis

　　　MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。

创建步骤如下：

一、使用IntelliJ IDEA 创建Maven管理的JAVA Web项目

①新建项目，选择Maven Module

在本地磁盘用户的。.m2目录下生成settings文件：

idea严格目录区分：main下必须书写java和resources,test也如此。

② 开发步骤：

书写pom.xnl下载所需jar

3.由于Maven对oracle数据库的不支持，我们需要将Oracle装载到本地仓库：

　(1).查询Oracle安装目录:D:\app\asus\product\11.2.0\dbhome_1\jdbc\lib

　　配置Maven3.3.9 bin到环境变量

然后可以通过cmd命令行 mvn -version测试有没有测试成功！！！

(2).定位到Oracle安装目录的jdbc文件夹

4.搭建分层架构---实现添加学生

实体类UserInfo:

package cn.hq.entity;
 
/**
 * Created by hq on 2017/1/16.
 */
public class UserInfo {
 
    private Integer id;
    private String name;
    private Integer age;
 
    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 Integer getAge() {
        return age;
    }
 
    public void setAge(Integer age) {
        this.age = age;
    }
}
　dao接口：　无需dao实现类，通过代理生成

public interface IUserInfoDao {
    public void add(UserInfo info);
 
}
　service层：

public interface IUserInfoService {
 
    public void add(UserInfo info);
}
　service实现类：

public class UserInfoServiceImpl implements IUserInfoService {
    private IUserInfoDao dao;
    public void add(UserInfo info) {
        dao.add(info);
    }
 
    public IUserInfoDao getDao() {
        return dao;
    }
 
    public void setDao(IUserInfoDao dao) {
        this.dao = dao;
    }
}

　控制器类：controller　

public class UserInfoController implements Controller {
 
    private IUserInfoService service;
 
    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
 
        String uname=httpServletRequest.getParameter("uname");
        Integer uage=Integer.valueOf(httpServletRequest.getParameter("uage"));
 
        UserInfo info=new UserInfo();
        info.setName(uname);
        info.setAge(uage);
 
        service.add(info);
 
        return new ModelAndView("/welcome.jsp");
    }
 
    public IUserInfoService getService() {
        return service;
    }
 
    public void setService(IUserInfoService service) {
        this.service = service;
    }
}

由于是整合MyBatis，需要书写核心配置文件：

小配置：UserInfoDao.xml:　

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 
 
<mapper namespace="cn.hq.dao.IUserInfoDao">
<select id="add" parameterType="UserInfo">
insert into userinfo values(SEQ_Num.nextval,#{name},#{age})
</select>
 
</mapper>

MyBatis配置文件：mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
 
<configuration>
<typeAliases>
<package name="cn.hq.entity"/>
</typeAliases>
 
<mappers>
 
<package name="cn.hq.dao"/>
 
</mappers>
</configuration>

　applicationContext.xml：进行植入dao、service、controller、事务管理器、数据源、sessionFactory
