spring+mybatis实现图书管理系统

一、流程
jsp页面发起请求-->控制器-->控制器通过一个service对象调用service方法-->service中通过xxxMapper对象调用dao中的方法-->查询数据库

二、图书管理系统
1、目录结构

2、Book实体类
package com.entity;
 
import java.io.Serializable;
import java.util.Map;
import org.apache.ibatis.type.Alias;
 
public class Book implements Serializable{
 
 
 private static final long serialVersionUID = 1L;
 private Integer id;
 private String name;
 private String author;
 private String bookconcern;
 private String date;
 private String synopsis; 
 private String pic;
  
 public String getPic() {
  return pic;
 }
 public void setPic(String pic) {
  this.pic = pic == null ? null : pic.trim();
 }
 
 public Book() {
  super();
 }
 public Book(Integer id, String name, String author,String bookconcern,String date,String synopsis,String pic) {
  super();
  this.id = id;
  this.name = name;
  this.author = author;
  this.bookconcern = bookconcern;
  this.date =date;
  this.synopsis = synopsis;
  this.pic = pic == null ? null : pic.trim();
 }
 
 
 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 getAuthor() {
  return author;
 }
 public void setAuthor(String author) {
  this.author = author;
 }
 public String getBookconcern() {
  return bookconcern;
 }
 public void setBookconcern(String bookconcern) {
  this.bookconcern = bookconcern;
 }
 public String getDate() {
  return date;
 }
 
 
 public void setDate(String date) {
  this.date = date;
 }
 
 
 public String getSynopsis() {
  return synopsis;
 }
 
 
 public void setSynopsis(String synopsis) {
  this.synopsis = synopsis;
 }
 public String toString() {
  return "Book [id=" + id + ", name=" + name + ", author="
    + author + ", bookconcern=" + bookconcern + ", date=" + date + ", synopsis=" + synopsis +", pic=" + pic+"]";
 }
 
}

3、BookMapper增删改查接口
package com.dao;
 
import java.util.List;
import org.springframework.web.multipart.MultipartFile;
import com.entity.Book;
 
public interface BookMapper {
 
 public Book getBookById(Integer id);
 public List<Book> getBooks(); 
 public void insertBook(Book book);
 public void deleteBookById(Integer id);
 public void updateBook(Book book);
 public Book findById(Integer id);
 
}

4、BookMapper.xml实现增删改查操作
<?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.dao.BookMapper">
 <select id="getBooks" resultType="com.entity.Book">
  select * from book
 </select>
  
    <insert id="insertBook" >
        insert into book
        (name,author,bookconcern,date,synopsis,pic)values(#{name},#{author},#{bookconcern},#{date},#{synopsis},#{pic});
    </insert>
 
    <delete id="deleteBookById" >
        delete from book
        where id=#{id}
    </delete>
  
    <update id="updateBook">
        update  book set
        name=#{name},author=#{author},bookconcern=#{bookconcern},date=#{date},synopsis=#{synopsis},pic=#{pic} where
        id=#{id} 
    </update>
    
    <select id="findById" parameterType="int" resultType="com.entity.Book">
        select *
        from book where id=#{id};
    </select>
    
</mapper>

5、控制类
package com.controller;
 
 
import java.io.File;
import java.io.IOException;
import java.util.List;
import java.util.Map;
import java.util.UUID;
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 org.springframework.web.multipart.MultipartFile;
import com.entity.Book;
import com.service.BookService;
 
 
@Controller
public class BookController {
 
 @Autowired
 BookService bookService;
 
 @RequestMapping("/getbooks")
 public String books(Map<String,Object> map){  
  List<Book> books = bookService.getBooks();
  map.put("allBooks", books);
  return "allbooks";
 }
 
 @RequestMapping(value="/insert",produces="text/html;charset=UTF-8")
    public String insert(){ 
        return "insert";
    }
 
    @RequestMapping(value="/insertBook")
    public String insertBook(Book book,MultipartFile book_pic) throws IllegalStateException, IOException{
     
        String originalFilename = book_pic.getOriginalFilename();
      if(book_pic!=null && originalFilename!=null && originalFilename.length()>0){      
       String pic_path = "E:\\spring_mybatis\\picture\\";    
       String newFileName = UUID.randomUUID() + originalFilename.substring(originalFilename.lastIndexOf("."));
       File newFile = new File(pic_path+newFileName);  
       book_pic.transferTo(newFile);  
       book.setPic(newFileName);  
      }
       bookService.insertBook(book);
       return "redirect:getbooks";
       }
 
    @RequestMapping(value="/deleteBookById")
    public String deleteBookById(Integer id){
        bookService.deleteBookById(id);
        return "redirect:getbooks";
    }
   
    @RequestMapping(value="/findById")
    public String findById(Model model,Integer id){
        Book book=bookService.findById(id);
        model.addAttribute("book",book);
        return "update";
    }
 
    @RequestMapping(value="/updateBook")
    public String updateBook(Book book,MultipartFile book_pic) throws IllegalStateException, IOException{
     
     String originalFilename = book_pic.getOriginalFilename();
  if(book_pic!=null && originalFilename!=null && originalFilename.length()>0){
   String pic_path = "E:\\spring_mybatis\\picture\\";    
   String newFileName = UUID.randomUUID() + originalFilename.substring(originalFilename.lastIndexOf("."));
   File newFile = new File(pic_path+newFileName);  
   book_pic.transferTo(newFile);  
   book.setPic(newFileName);  
  } 
       bookService.updateBook(book);    
      return "redirect:getbooks";
   
    }
 
}

6、BookService操作
package com.service;
 
import java.util.List;
import org.apache.ibatis.session.SqlSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import com.dao.BookMapper;
import com.entity.Book;
 
@Service    //标识这是一个业务类
public class BookService {
 
 @Autowired     //用@Autowired将BookMapper的接口对象注入到spring中
 private BookMapper bookMapper; 
 @Autowired
 private SqlSession sqlSession;
 
 public List<Book> getBooks(){
  return bookMapper.getBooks();
 }
 
  public void insertBook(Book book) {
         bookMapper.insertBook(book);   
     }
 
  public void deleteBookById(Integer id) {
         bookMapper.deleteBookById(id);
     }
 
  public void updateBook(Book book) {
         bookMapper.updateBook(book);
     }
 
  public Book findById(Integer id) {       
         return bookMapper.findById(id);
     } 
}
