一、目录结构

在这里插入图片描述

二、pojo

Book.java

package com.ly.pojo;
//实体类
public class Book {

    private Integer id;     //图书id
    private String name;    //图书名称
    private String publish;   //出版社
    private String author;  //作者

    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 getPublish() {
        return publish;
    }

    public void setPublish(String publish) {
        this.publish = publish;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }
}

public interface BookMapper {

    public Book findBookById(Integer id);

    public List<Book> findBookAll();

    public int insertBook(Book book);

    public int updateBook(Book book);
