基于spring、mybatis的图书管理系统

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 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

	
		select * from book
	
		
    
        insert into book
        (name,author,bookconcern,date,synopsis,pic)values(#{name},#{author},#{bookconcern},#{date},#{synopsis},#{pic});
    

    
        delete from book
        where id=#{id}
    
  
    
        update  book set
        name=#{name},author=#{author},bookconcern=#{bookconcern},date=#{date},synopsis=#{synopsis},pic=#{pic} where
        id=#{id} 
    
    
    
        select *
        from book where id=#{id};
    
    

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 map){		
		List 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 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);
	    }	
}
