zuul显示IO异常 : 你的主机中的软件中止了一个已建立的连接

我config中配置的虚拟路径代码如下:

    @Autowired
    private YmlConfig config;
        @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");

        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");

        registry.addResourceHandler("video/**")
                .addResourceLocations("file:"+config.getMapProps().get("videoSaveDir"));
    }

###错误信息如下:

经过多次检查,发现zuul在启动时会报上述错误,如果将config类中的

registry.addResourceHandler("video/")
.addResourceLocations("file:"+config.getMapProps().get("videoSaveDir"));**
这段代码去掉,则不会出现上述错误,但是由于文件存放在服务器目录中,必须配置文件虚拟路径,请问该如何解决

会漂移的树懒 仔细看了下,与video标签本身并没有关系,将视频路径直接粘贴到浏览器也依然会显示该异常

nginx代理zuul导致cookie失效的问题
docker里部署nginx,nginx端口80,zuul端口9090,用户服务端口8080 浏览器访问nginx静态资源login.html登录![图片说明](https://img-ask.csdn.net/upload/202001/04/1578111148_680898.png) form表单通过nginx和zuul进入后端的用户服务/user/login登录成功后response.addCookie,结果浏览器得到响应后没有收到cookie 直接访问zuul或者proxy_pass代理8080端口都没问题,nginx代理zuul后就拿不到了,请问是跨域的问题吗 这是nginx配置 ``` upstream backup { server 192.168.1.112:9090; } server { listen 80; server_name localhost; #charset koi8-r; #access_log /var/log/nginx/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.html; } location ~ ^/(user|goods|pay) { proxy_pass http://backup; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Scheme $scheme; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-For $remote_addr; proxy_pass_header Server; proxy_set_header Cookie $http_cookie; } } ```

Spring Cloud zuul问题:在使用中遇到了一个关于用户信息传递的问题
系统环境: web项目使用单点登录 通过zuul转发到请求到指定的服务端(zuul和服务端不做单点登录) 现在想要把当前登录的用户名传递到后端服务器,但是在zuul上通过过滤器设置 @Override public Object run() { RequestContext ctx = RequestContext.getCurrentContext(); HttpServletRequest request = ctx.getRequest(); request.setAttribute("username", request.getRemoteUser()); logger.info("登陆用户"+request.getRemoteUser()); logger.info("send {} request to {}",request.getMethod(),request.getRequestURL().toString()); return null; } 在zuul的过滤器中能获取到,但是在服务端并不能获取 求教要通过什么办法把参数传递到zuul之后的服务器
springcloud中zuul拦截不了header中的信息
为什么我用springcloud的zuul(单独做了一个微服务)时,添加zuulFilter也生效,run方法也是走的。听说不是会拦截header信息吗,但是我在服务真正被调用的一方查询header还是能得到header里信息,在zuulFilter的run方法中并没有做转发,就感觉zuulFilter并没有拦截header一样,不明所以~~~~
麻烦大神帮我看看这几个zuul的配置(基于springcloud)是什么意思?
![图片说明](https://img-ask.csdn.net/upload/202001/08/1578472990_336576.png) +++++++++ 这是一个关于商品的微服务里的yml文件配置 麻烦讲下这样配置完会有什么样的效果,谢谢

SpringCloud 微服务统一认证必须用Oauth吗?
最近刚刚接触微服务,有一个相关的项目。按照老师的要求要把登录单独作为一个微服务,此外还有仪器管理、人事管理和实验数据管理三个微服务(人事和数据都做好了,只是要整合进去)。 然后就遇到了好几个问题: 1、已经做好的人事和数据系统分别用的token和shiro的方式进行的登录,人事确实采用的是微服务的框架,但是把登录和人事管理做在一起了。如果要直接整合的话,仪器和数据怎么获得权限? 2、在网上查了几篇关于token的还有关于统一认证的,发现还有一个叫OAuth的东西,做统一认证必须要用这个吗?把token存放在redis里面,其它的微服务能不能直接读取到token?然后获取到了token,是不是直接用服务消费的方式就可以调用登录服务的函数获取权限信息??所以有没有大佬专门大佬专门写一篇帖子整理一下各种登录授权的方式,突然一下看这么多感觉很凌乱 3、怎样设置只能通过网关进行访问而禁止直接访问某个微服务?网上查看的帖子说的有禁用其它端口然后在网关中设置白名单,然后还有用spring cloud gateway来进行设置,这个和zuul有多大的区别?

feign的使用以及zuul是否与feign在功能上重复了
``` 一个项目里如果有客户端A,B,C,D。 是只需要将其中一个客户端配置成feign客户端, 还是应该额外提供一个feign客户端, 或者不额外提供feign客户端, 而是将所有客户端都配置成feign客户端。 如果说每个客户端都是feign客户端的, 那么对于另外的zuul客户端(非feign)来说, zuul的两个主要功能:负载均衡和流量入口,其中的负载均衡功能是否与feign功能重复了? ```
spring cloud 中zuul 请求https出现的问题
使用Sidecar做代理服务注册到eureka中,代理的服务是使用https协议,所以使用zuul的路由访问就会出现404,请问有什么好的解决方案吗?
SpringCloud zuul filter 执行时间过长
自己使用springcloud搭建了一套简单的网关,在做压测时发现时不时的会出现请求超时,排查了一下发现是zuul filter执行时间长,但实际上zuulfiter中并没有什么执行逻辑,自己在run中打印了执行时间,耗时是0毫秒;但是通过ctx.getFilterExecutionSummary()打印的执行时间却是1000+毫秒,看源码中zuulfilter的执行逻辑,也没发现有耗时的地方。使用的是2.0.3.Release版本,还请大神帮忙给看下,以下贴出主要代码。 自定义的父类,只是为了统一处理异常: ``` public abstract class GatewayFilter extends ZuulFilter { private static final Logger logger = LoggerFactory.getLogger(GatewayFilter.class); public abstract Object doRun() throws GatewayException; @Override public Object run() throws ZuulException { try { Object data = doRun(); return data; }catch (GatewayException ex){ throw new ZuulException(ex, ex.getCause().getMessage(), HttpStatus.INTERNAL_SERVER_ERROR.value(),ex.getMessage()); } } } ``` 自定义Filter,仅仅只是写入接到请求的时间: ``` public class PreAfterServlet30Filter extends GatewayFilter { private static final Logger logger = LoggerFactory.getLogger(PreAfterServlet30Filter.class); public PreAfterServlet30Filter() { } @Override public String filterType() { return PRE_TYPE; } @Override public int filterOrder() { return -2; } @Override public Object doRun() { long st = System.currentTimeMillis(); final RequestContext ctx = RequestContext.getCurrentContext(); final HttpServletRequest request = ctx.getRequest(); ctx.set("REQUEST_BEGIN_TIME",st); String requestUniqueKey = request.getParameter("uniqKey"); logger.info("PreAfterServlet30Filter, requestUniqueKey :{}, cost:{}" , new Object[]{requestUniqueKey , System.currentTimeMillis() - st}); return null; } @Override public boolean shouldFilter() { return true; } } ``` 日志输出信息: 2019-08-14 21:40:49.972 [http-nio-8080-exec-63] INFO c.xxx.PreAfterServlet30Filter - PreAfterServlet30Filter, requestUniqueKey :29d1f24c50fb55af0ce128f2977d12a4, **cost:0** 2019-08-14 21:40:51.434 [http-nio-8080-exec-63] WARN xxxx.PostRequestFilter - 127.0.0.1|/xxx.action|GET|29d1f24c50fb55af0ce128f2977d12a4|1462|ServletDetectionFilter[SUCCESS][0ms], Servlet30WrapperFilter[SUCCESS][0ms], PreAfterServlet30Filter[SUCCESS][ **1380ms** ], xxxFilter[SUCCESS][26ms], PreDecorationFilter[SUCCESS][0ms], xxxPreFilter[SUCCESS][27ms], xxxFilter[SUCCESS][0ms], xxxFilter[SUCCESS][28ms]ms]
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
