mall整合SpringSecurity和JWT实现认证和授权
本文主要讲解mall通过整合SpringSecurity和JWT实现后台用户的登录和授权功能，同时改造Swagger-UI的配置使其可以自动记住登录令牌进行发送。
项目使用框架介绍
SpringSecurity
SpringSecurity是一个强大的可高度定制的认证和授权框架，对于Spring应用来说它是一套Web安全标准。SpringSecurity注重于为Java应用提供认证和授权功能，像所有的Spring项目一样，它对自定义需求具有强大的扩展性。
JWT
JWT是JSON WEB TOKEN的缩写，它是基于 RFC 7519 标准定义的一种可以安全传输的的JSON对象，由于使用了数字签名，所以是可信任和安全的。
JWT的组成
JWT token的格式：header.payload.signatureheader中用于存放签名的生成算法 {"alg": "HS512"}Copy to clipboardErrorCopied payload中用于存放用户名、token的生成时间和过期时间 {"sub":"admin","created":1489079981393,"exp":1489684781}Copy to clipboardErrorCopied signature为以header和payload生成的签名，一旦header和payload被篡改，验证将失败 //secret为加密算法的密钥
String signature = HMACSHA512(base64UrlEncode(header) + "." +base64UrlEncode(payload),secret)Copy to clipboardErrorCopied
JWT实例
这是一个JWT的字符串

可以在该网站上获得解析结果：https://jwt.io/
JWT实现认证和授权的原理
用户调用登录接口，登录成功后获取到JWT的token；之后用户每次调用接口都在http的header中添加一个叫Authorization的头，值为JWT的token；后台程序通过对Authorization头中信息的解码及数字签名校验来获取其中的用户信息，从而实现认证和授权。
Hutool是一个丰富的Java开源工具包,它帮助我们简化每一行代码，减少每一个方法，mall项目采用了此工具包。
项目使用表说明
ums_admin：后台用户表ums_role：后台用户角色表ums_permission：后台用户权限表ums_admin_role_relation：后台用户和角色关系表，用户与角色是多对多关系ums_role_permission_relation：后台用户角色和权限关系表，角色与权限是多对多关系ums_admin_permission_relation：后台用户和权限关系表(除角色中定义的权限以外的加减权限)，加权限是指用户比角色多出的权限，减权限是指用户比角色少的权限

相关依赖及方法说明
configure(HttpSecurity httpSecurity)：用于配置需要拦截的url路径、jwt过滤器及出异常后的处理器；configure(AuthenticationManagerBuilder auth)：用于配置UserDetailsService及PasswordEncoder；RestfulAccessDeniedHandler：当用户没有访问权限时的处理器，用于返回JSON格式的处理结果；RestAuthenticationEntryPoint：当未登录或token失效时，返回JSON格式的结果；UserDetailsService:SpringSecurity定义的核心接口，用于根据用户名获取用户信息，需要自行实现；UserDetails：SpringSecurity定义用于封装用户信息的类（主要是用户信息和权限），需要自行实现；PasswordEncoder：SpringSecurity定义的用于对密码进行编码及比对的接口，目前使用的是BCryptPasswordEncoder；JwtAuthenticationTokenFilter：在用户名和密码校验前添加的过滤器，如果有jwt的token，会自行根据token信息进行登录。

public CommonResult<List<PmsBrand>> getBrandList() {

认证与授权流程演示
运行项目，访问API
Swagger api地址：http://localhost:8080/swagger-ui.html
未登录前访问接口
登录后访问接口
进行登录操作：登录帐号test 123456
点击Authorize按钮，在弹框中输入登录接口中获取到的token信息
登录后访问获取权限列表接口，发现已经可以正常访问
访问需要权限的接口
由于test帐号并没有设置任何权限，所以他无法访问具有pms:brand:read权限的获取品牌列表接口。
改用其他有权限的帐号登录
改用admin 123456登录后访问，点击Authorize按钮打开弹框,点击logout登出后再重新输入新token。
注意：如果admin帐号密码不对的话，公众号后台回复体验来获取。
