SpringCloud Ribbon 通过配置文件配置负载均衡策略无效

在看SpringCloud官方文档的时候,发现Ribbon可以通过配置文件方式来修改负载均衡策略,但是实际测试不生效。

yml配置如下:

# 服务提供者应用名称
sc-ribbon-producer:
  ribbon:
    # 指定服务提供者负载均衡策略
    NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule

实际测试中发现并没有使用随机策略,还是用的原始的轮询。

官方文档对应章节:
https://springcloud.cc/spring-cloud-dalston.html#_customizing_the_ribbon_client_using_properties

希望大神帮提点一下。

springcloud+zuul+Ribbon+Feign ,网关转发请求失效
微服务构架springcloud+zuul+Ribbon+Feign,目前注册中心有十几个服务,最近开发的这个服务A在测试环境下运行,刚开始没有任何问题,过大概半个小时之后,服务A就收不到前端发送过来的请求了,需要重启服务A才会恢复正常,但多一段时间之后又会出现同样的问题。查看网关的日志,在控制台能看到有send转发请求的日志,但是服务A并没有收到过网关来发过来的请求,网关跟服务A都没有任何的异常报错。图片1是网关的配置。图片二是服务A的部分配置。服务A的配置跟其他的服务的配置都相同。其他服务没出现类似的情况。另外服务A里有一个Socket服务,用来跟本地的服务进行数据传输处理。请各位大神帮分析下是哪里出了问题。 网关服务配置 ![图片说明](https://img-ask.csdn.net/upload/201905/08/1557304440_788490.png) 服务A配置: ![图片说明](https://img-ask.csdn.net/upload/201905/08/1557304457_238498.png) 网关打印日志![图片说明](https://img-ask.csdn.net/upload/201905/08/1557304607_574881.png)

ribbon,feign支不支持方法级别的配置
像dubbo就可以给每个方法配置超时时间,重试次数,容错策略,那springcloud可不可以呢 ``` <dubbo:reference> <dubbo:method name="findFoo" retries="2" /> </dubbo:reference> ```

com.netflix.zuul.exception.ZuulException: Forwarding error
我用的zuul是2.1.2版本,结果经常报这个错误。求大神指教!我看网上说在配置文件加: ribbon.ReadTimeout=10000, ribbon.ConnectTimeout=10000 ,都是胡说,完全不起作用。 <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-zuul</artifactId> <version>2.1.3.RELEASE</version> </dependency>
swing JRibbon如何监听到RibbonTask
最近在做swing ribbon相关的项目,请教大佬个问题。 ribbon添加了两个RibbonTask,使用ribbon的addChangeListener()监听方法,是否可以监听到两个task的切换呢? ribbon.addTask(ribbon1); ribbon.addTask(ribbon2); ribbon.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { System.out.println("change"); } }); ![图片说明](https://img-ask.csdn.net/upload/201910/29/1572313895_501524.jpg) 补充下,就是说图中两个页切换是否可以触发监听,我的没能监听到。 有什么方法可以监听到他俩的切换呢?
api-gateway feign,没有使用zuul,本机运行没问题,部署到同一台服务器上就出错

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。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
