微服务网关Zuul+Spring security+Oauth2.0+Jwt + 动态盐值 实现权限控制，开放接口平台

前言

网关作为整个微服务入口，在网关做认证授权既可以提前过滤不合法或过期的请求，又能让其他服务专做自身业务，不再关心令牌和权限问题。在集成过程中，选用的微服务版本为Greenwich.SR2，springboot版本以及security版本都为2.1.6.RELEASE，security每个版本的的实现有蛮大差异的。比如在2.0.1.RELEASE版在装载权限tag的时候是不需要带ROLE_前缀的，而2.1.6.RELEASE看源码得知需要自己拼接前缀。由于公司加密问题，项目不能放置外网，后续篇幅可能偏长，尽量每一步都贴清除，方便初学者少踩坑。但原理就读者自己去体会。

构建项目

eureka : 注册中心
common : 公用模块，放置其他服务公用的部分，可以不用
api-gateway : zuul集成security实现登录认证
auth-center : zuul集成security实现认证授权

common 模块

JwtProperties.java，这个版本验证 Authorization的时候截取了前6位，且已Bearer 开头，故在生成jwt的时候要拼接前缀，这个文件就用来读取默认配置的。

JwtTokenAuthenticationFilter.java ,由于过滤器中无法注入bean，故采用从spring上下文中获取。做全局异常处理，要抛出自定义异常可以先抛如controller中，当然这里采用了另外一种方式。这里实现了动态验签以及唯一登录。
