SpringBoot系列——Security + Layui实现一套权限管理后台模板

　　前言

　　Spring Security官网：https://spring.io/projects/spring-security

　　Spring Security是一个功能强大且高度可定制的身份验证和访问控制框架，侧重于为Java应用程序提供身份验证和授权。Security通过大量的拦截器进行校验，具体请看官网列出的列表：https://docs.spring.io/spring-security/site/docs/4.2.4.RELEASE/reference/htmlsingle/#ns-custom-filters

　　本文记录在SpringBoot项目中整合Spring Security进行权限控制，配合Layui，实现一套相对简单的权限管理后台模板

　　效果演示

　　我们可以利用配置文件的分支选择，设置开发环境不进行验证码校验，测试、生产环境再开启验证码校验，这样可以大大方便我们开发调试

　　xxx_huanzi，普通用户权限登录

　　xxx_sa、xxx_admin，管理员权限登录

　　退出登录

　　关键代码

　　数据表

　　首先我们要确定下我们需要哪些表，结构跟测试数据我一起贴出来

　　系统用户表

　　大家可能会发现我们的系统用户表有很多字段，又是限制IP地址、又是限制Mac地址，这是基于安全性考虑，系统可以能会限制用户的登录地址，这些字段都是一下安全性方面相关，但在这个例子了我并没有实现这些功能，大家可以沿着我的这个思路实现一下系统安全性功能

　　maven引包

　　Spring Boot提供了一个spring-boot-starter-security启动程序，它将Spring Security相关的依赖项聚合在一起，使用maven引入

        <!-- security安全校验 -->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-security</artifactId>

        </dependency>

　　生成后台代码

　　引好包后，使用我们的通用后台接口与代码自动生成工具，运行main方法直接生成这六个表的后台代码（不知道怎么操作的请看我之前的博客：SpringBoot系列——Spring-Data-JPA（究极进化版）自动生成单表基础增、删、改、查接口）

　　核心配置

　　核心配置在SecurityConfig

　　由此也扩展出了用户认证处理、密码处理、登录成功处理、登录失败处理、验证码处理、errorPage处理，这些我就不贴出来了，大家自己去看代码

　　后记

　　这只是一个简单的演示，数据都是直接在数据库插入的，应该做成在页面进行管理，比如：

　　更多的功能我就不展开了，大家直接进行扩展，本文就记录到这，有什么问题以后再进行补充，具体的代码已经放到GitHub、码云上了，SQL文件我也放在了里面，

　　大家可以搞下来跑一下，有什么建议或者问题都可以评论留言

　　代码开源

　　代码已经开源、托管到我的GitHub、码云：
