     简介：Java领域优质创作者、Java项目、学习资料、技术互助

    文末获取源码

    项目介绍

    项目主要包括管理员与用户两种角色；
    管理员角色包含以下功能：管理员登录,主页面,分类查看,修改个人信息,上传小说,查看小说,删除小说,评论顶收藏小说等功能。 
     

    用户角色包含以下功能：用户注册,用户登录,查看销售,查看小说,发布小说,搜索小说,查看个人信息等功能。

    环境需要

    1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
    2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
    3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
    4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 

    5.数据库：MySql 5.7版本；

    6.是否Maven项目：否

    技术栈

    1. 后端：servlet

    2. 前端：JSP+css+javascript+bootstrap+jQuery

    使用说明

    1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
    2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;
    若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；
    3. 将项目中util/DBUtil.java配置文件中的数据库配置改为自己的配置;

    4. 运行项目，输入localhost:8080/jsp_xiaoshuo_site
