# 一、设计思想 #

项目中计划实现的功能主要包括以下几点：

*  用户注册；
 *  用户的登录和退出；
 *  用户账号登录和注册时需要输入验证码验证；
 *  首页展示及分页，主要展示文章内容，可进行搜索，将搜索结果高亮显示；
 *  首页文章的点赞、踩和评论功能；
 *  个人主页模块，包括个人的基本信息，文章分类，发布文章，管理文章以及热门文章推荐等；
 *  书写文章功能；
 *  文章管理功能，包括文章的查看、修改和删除；
 *  个人信息修改功能；
 *  安全框架 spring-security 的整合，对不符合条件的用户或者 URL 进行拦截；
 *  记录用户登录信息，包括登录的时间、IP 等；
 *

# 二、表结构设计 #

创建数据表

# 三、反向生成实体类 #

## 1. 准备好生成工具包 ##

## 2. 配置生成文件 ##

generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>    
        <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

            <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

        </context>    
    </generatorConfiguration>  
    复制代码

## 3. 在该文件中打开cmd，输入生成命令 ##

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite
    复制代码

## 4. 将生成结果拷贝到项目文件夹中 ##
