1.导包

2.准备数据库表

#创建数据库ssm
drop database if exists ssm;
create database ssm;
use ssm;
#创建书本表
drop table if exists ssm_book; 
create table ssm_book (
	id int(11) primary key auto_increment not null,
    name varchar(111),
    detail varchar(256),
    userId int(22)
);
 
insert into ssm_book(id, name,detail,userId) values
(1,"javaWeb","JavaWeb从入门到精通",1),
(2,"PhotoShop","图片图像处理",1),
(3,"mysql从入门到精通","数据库专业书籍",2);
 
select * from ssm_book;
 
# 创建用户表
create table ssm_user (
	id int(11) primary key auto_increment not null,
    username varchar(111),
    password varchar(256)
);
 
insert into ssm_user(id, username,password) values
(1,"aa","aa"),
(2,"bb","bb"),
(3,"cc","cc");
select * from ssm_userssm_user;
 
select * from ssm_book where userId = 1;

3.准备pojo

 3.1.Book.java

package com.ssm.pojo;
 
public class Book {
	private Integer id;
	private String name;
	private String detail;
	private Integer userId;
	
	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 getDetail() {
		return detail;
	}
	public void setDetail(String detail) {
		this.detail = detail;
	}
	
	public Integer getUserId() {
		return userId;
	}
	public void setUserId(Integer userId) {
		this.userId = userId;
	}
	@Override
	public String toString() {
		return "Book [id=" + id + ", name=" + name + ", detail=" + detail + ", userId=" + userId + "]";
	}
	
}

3.2.User.java

package com.ssm.pojo;
 
public class User {
	private Integer id;
	private String username;
	private String password;
	
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [username=" + username + ", password=" + password + "]";
	}
}

4. 准备jdbc.properties文件

我直接放在了src下

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=admin

5.applicationContext.xml配置文件 

<?xml version="1.0" encoding="UTF-8"?>

</beans>

 6.springMVC.xml配置文件

<?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:p="http://www.springframework.org/schema/p"

	</bean>
</beans>

7.dao之mapper

由于在applicationContext.xml配置了自动扫描mapper，所以需要把mapper类和其对应的mapper.xml文件放在同一目录下，命名也是一样

7.1.BookMapper.java

package com.ssm.mapper;
 
import java.util.List;
 
import com.ssm.pojo.Book;
 
public interface BookMapper {
	//添加一本书
	public void addBook(Book book);
	
	//根据id删除一本书
	public void deleteBookById(Integer id);
	
	//根据ID查询书
	public Book findBookById(Integer id);
	
	//根据书名模糊查询书
	public List<Book> findBooksByKeyname(String keyname);
	
	//根据id编辑修改书的信息
	public void editBookInformationById(Book book);
	
	//根据用户id查询
	public List<Book> findBooksByUserId(Integer userId);
}

7.2.BookMapper.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="com.ssm.mapper.BookMapper">
	<insert id="addBook" parameterType="com.ssm.pojo.Book" >
		insert into ssm_book(id, name,detail,userId) values(#{id},#{name},#{detail},#{userId})
	</insert>
	
	<delete id="deleteBookById" parameterType="Integer">
		delete from ssm_book where id = #{id}"
	</delete>
	
	<select id="findBookById" parameterType="Integer" resultType="com.ssm.pojo.Book">
		select * from ssm_book where id = #{id}
	</select>
	
	<select id="findBooksByKeyname" parameterType="String" resultType="com.ssm.pojo.Book">
		select * from ssm_book where name = "%"#{value}"%"
	</select>
	
	<update id="editBookInformationById" parameterType="Integer">
		update ssm_book 
		set name=#{name},detail=#{detail},userId=#{userId}
		where id=#{id}
	</update>
	
	<select id="findBooksByUserId" parameterType="Integer" resultType="com.ssm.pojo.Book">
		select * from ssm_book where userId = #{value}
	</select>
</mapper>

7.3.UserMapper.java

package com.ssm.mapper;
 
import org.apache.ibatis.annotations.Param;
 
import com.ssm.pojo.User;
 
public interface UserMapper {
	//查找用户
	public User findUserbyNameAndPwd(@Param("username") String username,@Param("password") String password);
	public User findUserbyName(String username);
}

7.4.UserMapper.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="com.ssm.mapper.UserMapper">
	<select id="findUserbyNameAndPwd" resultType="com.ssm.pojo.User">
		select * from ssm_user where username=#{username,jdbcType=VARCHAR} and password=#{password,jdbcType=VARCHAR}
	</select>
	
	<select id="findUserbyName" parameterType="String" resultType="com.ssm.pojo.User">
		select * from ssm_user where username=#{username}
	</select>
</mapper> 

 8.Controller层

package com.ssm.controller;
 
import java.util.List;
 
import javax.servlet.http.HttpSession;
 
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 com.ssm.pojo.Book;
import com.ssm.pojo.User;
import com.ssm.service.BookService;
import com.ssm.service.LoginService;
 
 
@Controller
 
public class Login {
	/**
	 * @author AL
	 * 登录
	 */
	@Autowired
	private LoginService loginService;
	@Autowired
	private BookService bookService;
	
	@RequestMapping("login")
	public String login(String username,String password,Model model) {
		User user = this.loginService.findUserByNameAndPwd(username,password);
		
		if(user!=null) {
			Integer userId = user.getId();
			List<Book> books = bookService.findBooksByUserId(userId);
			for(Book book : books) {
				System.out.println(book);
			}
			model.addAttribute("user",user);
			model.addAttribute("books",books);
			return "my";
		}
		
		return "index";
		
	}
	
}

 9.Service层

9.1.BookService接口

用于操作书籍

package com.ssm.service;
 
import java.util.List;
 
import com.ssm.pojo.Book;
 
public interface BookService {
	public List<Book> findBooksByUserId(Integer userId);
}

9.2.BookServiceImpl实现类

package com.ssm.service;
 
import java.util.List;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import com.ssm.mapper.BookMapper;
import com.ssm.pojo.Book;
 
@Service
public class BookServiceImpl implements BookService {
 
	@Autowired
	private BookMapper bookMapper;
	
	@Override
	public List<Book> findBooksByUserId(Integer userId) {
		List<Book> books = bookMapper.findBooksByUserId(userId);
		return books;
	}
 
}

9.3.登录接口

package com.ssm.service;
 
import com.ssm.pojo.User;
 
public interface LoginService {
 
	public User findUserByNameAndPwd(String username, String password);
 
}

 9.4.登录实现类

package com.ssm.service;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import com.ssm.mapper.UserMapper;
import com.ssm.pojo.User;
 
@Service
public class LoginServiceImpl implements LoginService {
 
	@Autowired
	private UserMapper userMapper;
	
	@Override
	public User findUserByNameAndPwd(String username, String password) {
		User user = userMapper.findUserbyNameAndPwd(username, password);
		
 
		return user;
	}
}

10.页面导入到WEB-INF下
