micro-oauth2-api不整合Spring Security+Oauth2如何拿到当前登录的用户ID呢

如题，麻烦大佬解惑~

Mac环境下启动EurekaClient时，无法connect到Sercer

micro-oauth2 如何注销登录？

监控面板无法打开

jwk-set-uri 能否从注册中心获取？

示例代码中 jwk-set-uri 的地址是写死的，对于微服务多实例不友好，
能否改成通过注册中心获取？

eureka-server 启动报错

如下

Caused by: java.lang.ClassNotFoundException: javax.ws.rs.ext.MessageBodyReader

公众号文章 eureka 集群配置时为什么要注册中心之间互相注册？

我运行时报错，且 DS Replicas 中没有另一个注册中心。将 fetch-registry 和 register-with-euraka 改成 false 才能显示出正常效果

springcloud学习教程 Hystrix:服务容错保护链接错误问题

"使用ignoreExceptions忽略某些异常降级" 这里
====>调用接口进行测试：http://localhost:8401/user/tesException/1<===
这里的地址错了吧,tesException应该改成testException

客户端的yml配置: spring.oauth2.resource.jwt.key-uri作用是什么?

1 注释了客户端启动不起来,在网上找了下解释说: "解析jwt令牌所需要密钥的地址,",

springcloud-learning/tree/master/micro-oauth2项目里，如果用容器部署的，这个证书好设置吗？

micro-oauth2 获取到token后访问hello接口返回暂未登录或token已经过期

http://localhost:9201/api/hello
Authorization = eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJtYWNybyIsInNjb3BlIjpbImFsbCJdLCJpZCI6MSwiZXhwIjoxNjAwNzE1NzEzLCJhdXRob3JpdGllcyI6WyJBRE1JTiJdLCJqdGkiOiI0MjkxNGNlMS05MGEwLTRkOTItYjRmNi1iY2JiYWQ2NjcwZmUiLCJjbGllbnRfaWQiOiJjbGllbnQtYXBwIn0.Ecv7MqyxyEPMF2ZUD3imcu5VmlqV2aTyyD_RzbZbprnpPAxOjb_TpVsV1z_bXs8YZYaeWWqeOq2w0NAdTY1FSPC0ylDj4bDZh_79xGSf2WoAM0rbrui2Ae93heCJ4D_aVTRNWi4cWAp8YaRTA712mmoOazvSBdKLz2iRMxz7ZqhHgMBS0OkJu3S129rZzZab5DeRVDJpn0IwFkbqTuDRGCYf9ELVjxeJZsq0iLGKYStKDifkVPPRI9UkWFLw1hE2k3Jk3uj-SYrv6_KoXyRYmGnH6eBMoCIJR97Y4nHpR2bY-PMPIeNbhW_iE8eeal1HPFi9rneLxyZGSQOKlKzYuQ

config-server不能刷新消息总线的bug

在使用消息总线的时候，config-server还需要一个依赖包spring-boot-starter-web

是否可以不使用redis

如果不需要人为让token失效的功能，是否可以去掉redis? 我尝试去掉redis，但是对api的保护也没有了，请问应该如何更改代码？

新版本

不考虑出个新版本的吗，毕竟改动挺大的。

micro-oauth2 微服务解决方案里面，用组件化配置去代替过期的WebSecurityConfigurerAdapter，会报错

这是组件化配置

这是报错

感觉像是依赖冲突导致的，各位有什么好的解决方案吗

oauth2-jwt-server 的密码模式无法正常使用，访问 /oauth/token 返回 401

这里的鉴权仅仅适用于后端管理系统吧？

这里的鉴权仅仅适用于后端管理系统的用户吧吧？

而C端的用户应该是不存在什么角色、权限之类的吧

micro-auth2 的权限规则匹配缺陷较严重

不支持url模板校验、解析等
像：/xxx/{id} , /xxx/ 这些没法匹配。

micro-oauth2 中不走网关请求资源服务不需要认证吗？

单独请求资源服务(不走网关)，是可以直接请求的。正常开发，资源服务还需要单独写认证和鉴权吗

eureka-client注册到有登录认证的注册中心按步骤操作的但是启动不了client

项目中spring boot和Spring Cloud 版本对应关系

你好：
我在Spring Cloud Greenwich.SR2 【源码位置：https://github.com/spring-cloud/spring-cloud-release/releases/tag/vGreenwich.SR2】
的 spring-cloud-starter-parent的pom.xml中查看有：

org.springframework.boot spring-boot-starter-parent 2.1.6.RELEASE org.springframework.cloud spring-cloud-starter-parent Greenwich.SR2 spring-cloud-starter-parent Spring Cloud Starter Parent 也就是说Greenwich.SR2 版本基于 spring boot 2.1.6 .

我的疑问是：
1：当我使用Greenwich.SR2 版本的时候，我的spring boot 版本是必须大于等于2.1.6 版本吗？
2：自然，该项目中使用 Greenwich.SR2 版本,spring boot 是 2.1.7 能否作为问题1的答案呢？

授权服务使用WebSecurityConfigurerAdapter过期，换成了SecurityFilterChain的Bean，但启动报"Found WebSecurityConfigurerAdapter as well as SecurityFilterChain. Please select just one"

    @Bean
    public SecurityFilterChain filterChain() throws Exception {
//        new AntPathRequestMatcher("/rsa/publicKey")
        return new DefaultSecurityFilterChain(EndpointRequest.toAnyEndpoint(), Collections.emptyList());
//        http.authorizeRequests()
//                .requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
//                .antMatchers("/rsa/publicKey").permitAll()
//                .anyRequest().authenticated();
//        return http.build();
    }

报错:

导入后报了这个错，有遇见的吗

增加授权码模式后，以授权码模式测试发现登录成功后无法正常跳转授权页面！

token正常失效后再访问网关直接返回401不走拦截器

ServerAuthenticationEntryPoint 这个拦截器没走，网关直接响应401 不知道该从哪拦截了。。。
