spring cloud oauth2 feign 遇到的坑
关于oauth2相关的内容这里不重复描述，在spring cloud中在管理内部api时鉴权相信有很多人会有疑问，这里描述两种比较low的用法，由于公司内部使用的是阿里云edas这里仅仅是记录一下，如果有更好的用法在请赐教，不喜勿喷！
客户端模式
提供三方jar包
这里需要抽一个jar包,需要用到feign的为服务端直接利用maven模式引入feign即可

到此客户端模式配置完成!
基于spring security
开放权限,利用url规范来规划客户端的url不通过auth2鉴权,这里唯一的区别是在feign拦截器里处理的逻辑改一下，代码如下

@Autowiredprivate OAuth2ClientContext context;@Override public void apply(RequestTemplate template) { if(context.getAccessToken() != null && context.getAccessToken().getValue() != null && OAuth2AccessToken.BEARER_TYPE.equalsIgnoreCase(context.getAccessToken().getTokenType()) ){ template.header("Authorization", String.format("%s %s", OAuth2AccessToken.BEARER_TYPE, context.getAccessToken().getValue())); } } |
spring cloud微服务增加oauth2权限后 feign调用报null
在授权服务里，用户通过用户名密码，或者手机和验证码等方式登陆之后，在http头里会有授权的标识，在客户端调用时，需要添加当时有效的token才可以正常访问被授权的页面。

Content-Type:application/jsonAuthorization:Bearer d79c064c-8675-4047-a119-fac692e447e8 |
而在业务层里，服务与服务之间使用feign来实现调用，而授权的代码我们可以通过拦截器实现，在feign请求之前，把当前服务的token添加到目标服务的请求头就可以了
一般是这样实现的

上面的拦截器代码没有什么问题，也很好理解，但事实上，当你的feign开启了hystrix功能，如果开启了，需要把hystrix的策略进行修改，默认是THREAD的，这个级别时ThreadLocal是空的，所以你的授权不能传给feign的拦截器.

以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
