今天就来进行实体以及表结构的设计
文档写的不标准，一开始想先定义一下实体，最后写着写着写把表关系也给写上了
有什么不足希望大家多多指出
实体设计
用户实体
user
Long id; // id
String username; // 用户名
String password; // 密码
String phone; // 电话号码
String u_photo; // 头像
String slat; // 盐
分类
category
Long id;
String type_name;
String type_info;
String icon_url;
图书信息
book
Long id;
String title; // 书名
String intro; // 简介
Long a_id; // 作者id
String book_comment; // 书评
String image; // 封面
Date creatDate; // 起始更新时间
int chapter_number; // 章节数量
Date updateDate; // 最后更新时间
int state; // 状态 1:完结 0:未完结
String protagonist; // 主角
Long c_id; // 分类id
图书热度
book_hot
Long b_id; // 图书id
int click_num; // 点击量
int search_num; // 搜索量
int hot; // 热度
图书章节
chapter
Long id; // id
int sequence_num; // 章节序号
String title; // 章节名
