            搭建一个简单的SSM框架，分享给大家，以后自己也可以拿出来用

1.用maven项目管理工具搭建一个简单SSM的demo：工具Eclipse,Mysql-5.5,Tomcat-7.0,Maven-3.0,jdk-1.8

         （1） 新建一个手把手搭建SSM框架动态web项目，当然也可以建一个Java普通项目，

         （2）Dynamic Web Project手把手搭建SSM框架

选择好你需要设置的配置和tomcat版本，点击下一步手把手搭建SSM框架

可以添加一个resources文件夹，方便后面我们存放各种配置文件。点击下一步手把手搭建SSM框架记得把这个勾选上，是后面需要设置的一个web.xml文件。

            （3）这样我们就创建好了一个动态Web项目手把手搭建SSM框架

                  （4）右击项目名，选择下面的Configure==>Convert to Maven Project手把手搭建SSM框架

点击完成就行，加入Maven项目管理工具能使我们在做项目省很多心思。

手把手搭建SSM框架

我们需要在这个pom.xml写我们需要的引入依赖包及版本，大家可以上maven仓库查找需要的版本http://mvnrepository.com/

   3.写入环境

    （1）jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/ssm2?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&maxReconnects=10

jdbc.username=root

jdbc.password=123456

    （2）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>
    <!-- 配置全局属性 -->
    <settings>
        <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
        <setting name="useGeneratedKeys" value="true" />


        <!-- 使用列别名替换列名 默认:true -->
        <setting name="useColumnLabel" value="true" />


        <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
    </settings>
</configuration>

后面我是将spring配置文件分为3个部分，方便我们管理

4.创建项目骨架

手把手搭建SSM框架

基本的结构，还可以分mapper包，放mybatis的映射文件

（1）User.java实体类
package cn.ssm.entity;

public class User {
	private Integer id;
	private String code;
	private String password;
	private String name;
	private String phone;
	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 String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	
	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", code=" + code + ", name=" + name + ", phone=" + phone + "]";
	}	
}

     (2)UserDao.java用户接口

package cn.ssm.dao;

import cn.ssm.entity.User;

public interface UserDao {
	void login(String code,String password);//登陆
	int add(User user);//注册
	int queryAllById(int id);//查询
}
    （3）UserDao.xml   UserMapper

        

<?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.smm.dao.UserDao">
    <!-- 目的：为dao接口方法提供sql语句配置 -->
    <!-- 登陆验证 -->
    <select id="login" parameterType="map">
    	SELECT            
            code,
            password
        FROM
            user
      	where
      		code=#{code}
      		and
      		password=#{password}
    </select>
    <!-- 查询 -->
    <select id="queryAllById" resultType="User" parameterType="int">
        SELECT
            id,
            code,
            name,
            phone,            
        FROM
            user
      	WHERE
      		id=#{id}
    </select>
    
	<!-- 添加用户 -->	
   	<insert id="add" resultType="int" parameterType="User">
        insert into
        	user(        	
        	code,
        	password,
        	name,
        	phone)
        values(            
            code=#{code},
            password=#{password},
            name=#{name},
            phone=#{phone})         
    </insert>	
</mapper>

        (4)UserService.java 

package cn.ssm.service;

import cn.ssm.entity.User;

public interface UserService {
	/** 
     * 登录验证 
     * @param account 登录账号 
     * @param userPassword 密码 
     * @return  validate true通过 false未通过 
     * @throws Exception 
     */  
    User login(String code, String password) throws Exception; 
    /**
     * 注册
     * @param user
     */
    int add(User user)throws Exception;
    /**
     * ID查询
     * @param id
     * @return
     * @throws Exception
     */
    User queryById(int id)throws Exception;
}

        (5)UserServiceImpl.java

package cn.ssm.service;


import org.springframework.beans.factory.annotation.Autowired;

import cn.ssm.dao.UserDao;
import cn.ssm.entity.User;

public class UserServiceImpl implements UserService {
	@Autowired
	UserDao userDao;
	@Override
	public User login(String code, String password) throws Exception {
		
		return userDao.login(code, password);
	}

	@Override
	public int add(User user) throws Exception {
		
		return userDao.add(user);
	}

	@Override
	public User queryById(int id) throws Exception {
		
		return userDao.queryById(id);
	}

}

        (6)UserCtroller.java

package cn.ssm.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.ssm.entity.User;
import cn.ssm.service.UserService;

@Controller
@RequestMapping("/user")
public class UserCtroller {
	@Autowired
	UserService userService;

	@RequestMapping("login")
	public String login(String code, String password, Model model) throws Exception {
		System.out.println("用户登陆" + code + password);
		userService.login(code, password);		
		model.addAttribute("sg", "登陆成功");
		return "show";

	}

	@RequestMapping("add")
	public String add(User user, Model model) throws Exception {
		System.out.println("用户注册" + user.getCode() + user.getPassword());

		int addUser = userService.add(user);
		model.addAttribute("sg", "注册成功");

		if (addUser == 1) {
			return "login";
		}
		return null;

	}

	@RequestMapping("query")
	public String queryById(int id, Model model) throws Exception {
		System.out.println("查询id" + id);
		userService.queryById(id);
		model.addAttribute("sg", "查询结果");
		return "show";

	}
}
