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 feign 启用hystrix引发的调用问题

版本: spring cloud :Edgware.SR3(使用 spring cloud starter openfeign 1.4.4) springboot :1.5.12 问题: 我使用feign.hystrix.enable=true.启用了hystrix,然后我需要的效果是达到设置的超时时间才需要进入feignclient 注解的fallback方法. 但是!!!现在我只要一启用了feign.hystrix.enable=true这个配置,进行调用时,直接进入了fallback方法.然而我手动配置的超时时间不生效. 使用的配置如下: ``` feign: hystrix: enabled: true okhttp: enabled: true httpclient: enabled: false hystrix: threadpool: default: coreSize: 500 maxQueueSize: 1000 queueSizeRejectionThreshold: 800 command: default: execution: timeout: enabled: true isolation: thread: timeoutInMilliseconds: 60000 ribbon: eureka: enabled: true ReadTimeout: 60000 ConnectTimeout: 60000 ``` </br> 请大家帮忙看看.Thx

feign怎么携带cookie访问

我在一个系统中登录成功后，需要调用本地服务接口，但是本地服务接口需要验证登录，由于feign的内网调用效率高 所以采用feign，但是现在总是提示登录失效。所以想请教下大神们，有没有知道怎么让feign携带登录后的cookie访问的方法？

Feign在开启Hystrix后，feign.client超时时间设置有什么用？

1、Feign开启Hystrix 配置文件如下： ``` feign: hystrix: enabled: true ``` 2、配置feign客户端超时时间： ``` feign: client: config: default: connectTimeout: 8000 readTimeout: 10000 ``` 请求一个休眠6秒的接口，会超时。 3、当配置Hystrix超时时间后，能正常访问，配置如下： ``` hystrix: shareSecurityContext: true command: default: execution: isolation: thread: timeoutInMilliseconds: 8000 ``` 请问：feign.client的超时时间配置有什么用？

SpringCloud Feign调用返回结果封装后异常问题

我一个项目采用SpringCloud框架，服务端客户端采用Feign调用。 服务端返回结果封装了一个Result对象来进行包装    然后服务端的一个登录方法  客户端用Feign调用  但是测试的时候，无论服务端返回各种结果都是报错，报枚举类超出范围异常,Feign已拿到值，但是都是报那个Code的超出枚举类异常，但是枚举类是已经定义了。  麻烦各位大神能帮忙看看解决一下嘛，谢谢各位大神

springcloud feign 注解 RequestLine 相对于 RequestMapping有什么优势吗？

目前springcloud项目 对外暴露的接口上面url用@requestMapping注解的， 但是我觉得用RequestLine更合适 因为这是Feign的注解，对外暴露也是用Feign的，请问 如题，注解 RequestLine 相对于 RequestMapping有什么优势吗？

springcloud feign 找不到服务 value 和 url

找到原因了 eureka没有注册外网ip ，feign根据拿到的ip 不是正确的ip ------------------------------------------------------------ 服务提供者 和 消费者 部署在一台机子上 什么问题都没有 但是部署在2台机子时 feign超时 ribbon.ReadTimeout 和ribbon.ConnectTimeout 都已经调到很大了（我觉得是找不到微服务） 这时 把@FeignClient 的value 换成 url 不通过微服务名字 直接通过 ip和端口 不到1秒可以找到 通过value 微服务名字 ribbon.ReadTimeout设置10秒还是找不到 （微服务 服务方可以正常调用 ， 注册中心 服务名字 和 feign的value 也是一样，部署在同一个机子上没出现问题） .  .  .  . 

feign MultipartFile fastdfs跨服务调用文件上传

基本情况是： 不是通过浏览器请求，是微服务中在服务启动后自动把制定目录下的文件，通过feign调用文件上传接口，将文件保存到服务器。 参考了各位的建议之后，还是报相同的错误。 贴出一段idea中的异常信息： feign.FeignException: status 500 reading RemoteFdfsService#fdfsUpload(MultipartFile); content: {"msg":"Current request is not a multipart request","code":1,"data":null} at feign.FeignException.errorStatus(FeignException.java:60) at feign.codec.ErrorDecoder$Default.decode(ErrorDecoder.java:89) at feign.SynchronousMethodHandler.executeAndDecode(SynchronousMethodHandler.java:143) at feign.SynchronousMethodHandler.invoke(SynchronousMethodHandler.java:77) at feign.hystrix.HystrixInvocationHandler$1.run(HystrixInvocationHandler.java:107) at com.netflix.hystrix.HystrixCommand$2.call(HystrixCommand.java:302) at com.netflix.hystrix.HystrixCommand$2.call(HystrixCommand.java:298) at rx.internal.operators.OnSubscribeDefer.call(OnSubscribeDefer.java:46) at rx.internal.operators.OnSubscribeDefer.call(OnSubscribeDefer.java:35) 调用部分代码（接口需要的是MultipartFile的文件参数） String filePath = "F:\\mac\\pic\\20181113184344_type[0]_ItsPlate.jpg"; File file = new File(filePath); FileInputStream fileInputStream = new FileInputStream(file); MultipartFile multipartFile = new MockMultipartFile(file.getName(), fileInputStream); String url = remoteFdfsService.fdfsUpload(multipartFile); feign： @FeignClient(value = ServiceNameConstant.FDFS_SERVICE, configuration = RemoteFdfsService.MultipartSupportConfig.class, fallbackFactory = RemoteFdfsServiceFallbackFactory.class) public interface RemoteFdfsService { /** * 上传图片并且生成缩略图 * @param file * @return */ @PostMapping(value = "/fdfs/upload_image", consumes = MediaType.MULTIPART_FORM_DATA_VALUE) String fdfsUploadImage(@RequestPart(value = "file") MultipartFile file); /** * 引用配置类MultipartSupportConfig.并且实例化 */ @Configuration class MultipartSupportConfig { @Bean public Encoder feignFormEncoder() { return new SpringFormEncoder(); } } } 烦请各路上仙指点一二，多谢。

feign的默认负载均衡失效？

在spring Cloud 中，用consul 搭建了两个服务做集群，用feign进行访问，但是一直访问第一台，负载均衡失效，关闭第一台，就能访问到第二台，这时候，开启第一台，后面调用，就不会访问到第一台，只访问第二台.

访问redis快 还是访问feign-client api快

请问，微服务中，在服务A与服务B, 是通过共用redis 通信 还是通过feign-client通信？ 访问redis速度快 还是访问feign-client api 速度快？？

求助大神帮忙看看，关于feign调用的一个问题，卡在那里直到超时

feign 调用其他服务将接口打jar包还是通过接口重写一样的接口进行调用

请问 一下 feign 调用其他服务, 一般通过对方服务将接口打jar包，通过依赖jar使用；还是通过需要什么接口重写一样的接口进行调用，哪一种是比较推崇的？

Feign通过代码和yml配置都无法打印日志

1. 通过代码配置 配置类加了@Configuration，并且不再被Spring重复组件扫描，有如下配置， @Bean public Logger.Level feignLoggerLevel() { return Logger.Level.FULL; } FeignClient也添加了@FeignClient（name="serviceId", configuration=上面配置类.class） 无法打出日志 2. 通过yml配置也无法打印日志 logger: level: FeignClient全限定名: DEBUG 基本是照着视频和博客抄，但是都无法打印出日志。 feign版本： <properties> <feign.version>9.5.1</feign.version> </properties>

SpringCloud Feign 替换默认配置，不加 @Configuration怎么理解？

### SpringCloud Feign 替换默认配置，不加 @Configuration怎么理解？ ### 在学习Feign的时候有看到替换默认配置要么把配置类创建到启动类外层目录，这样要加@Configuration注解，要么是放在同级或下级目录，此时不加@Configuration。 ### 但是实际实验结果表示，放在同级或下级目录，不加@Configuration，则会报错，或者不生效。 ### 那么该怎么理解官方文档的这段话呢？ > FooConfiguration不需要使用@Configuration注释。但是，如果是，则请注意将其从任何@ComponentScan中排除，否则将包含此配置，因为它将成为feign.Decoder，feign.Encoder，feign.Contract等的默认来源，指定时。这可以通过将其放置在任何@ComponentScan或@SpringBootApplication的单独的不重叠的包中，或者可以在@ComponentScan中明确排除。 ### 相关代码 ``` java // 启动类在com.vvlin包下 package com.vvlin.config; ... // 这里注释掉之后，不会在控制台打印，说明方法未调用 // 不注释则正常 // @Configuration public class FeignUploadFileConfiguration { @Bean public Encoder feignFormEncoder() { System.err.println("FeignUploadFileConfiguration.feignFormEncoder()"); return new springFormEncoder(); } } ```

程序员一般通过什么途径接私活？

二哥，你好，我想知道一般程序猿都如何接私活，我也想接，能告诉我一些方法吗？ 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”，还有很多读者问过我类似这样的问题。 我接的私活不算多，挣到的钱也没有多少，加起来不到 20W。说实话，这个数目说出来我是有点心虚的，毕竟太少了，大家轻喷。但我想，恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉，我也算是有经验的人了。 唾弃接私活、做外...

Python爬虫精简步骤1 获取数据

爬虫，从本质上来说，就是利用程序在网上拿到对我们有价值的数据。 爬虫能做很多事，能做商业分析，也能做生活助手，比如：分析北京近两年二手房成交均价是多少？广州的Python工程师平均薪资是多少？北京哪家餐厅粤菜最好吃？等等。 这是个人利用爬虫所做到的事情，而公司，同样可以利用爬虫来实现巨大的商业价值。比如你所熟悉的搜索引擎——百度和谷歌，它们的核心技术之一也是爬虫，而且是超级爬虫。 从搜索巨头到人工...
