在SpringCloud中Hystrix和Feign的集成十分方便。在客户端我们需要使用@EnableCircuitBreaker启用熔断机制。 @SpringBootApplication @EnableEurekaClient@EnableFeignClients(defaultConfiguration= FeignClientsConfiguration.class)@EnableCircuitBreakerpublicclassWebApplicationStarter {publicstaticvoidmain(String[] args) { SpringAp...

Spring Cloud 2.x系列之RestTemplate+Ribbon整合断路器Hystrix,这篇来看看如何Feign整合断路器Hystrix,Feign整合断路器Hystrix也是相对比较简单的。Feign默认已经自带断路器Hystrix,所以不需要像RestTemplate+Ribbon整合断路器Hystrix那样需要在SpringBoot的启动类添加注解。但是Feign自带断路器并没有打开,需要做些额外的配置。 f...

Feign是自带断路器的,在D版本的Spring Cloud之后,它没有默认打开。需要在配置文件中配置打开它,在配置文件加以下代码: #为了打开 feign 的 hystrix 功能 feign: hystrix: enabled: true 完整配置文件如下: server: port: 8763 spring: application: name: client01 ...
2. Setting Up Feign Client with Spring Boot Let’s set up a simple Spring Boot web application and enable it to use the Feign Client. 2.1. Maven In order to use Feign Client, we would need to add the spring-cloud-starter-openfeign dependency. Since we are creating a web application, ...

我用的spring boot是 3.2.5,由于用的feign,就直接选择了hystrix,但是发现一直进不去。我的代码实现如下: 1. 定义容错的处理类 当调用远程接口失败或超时时,会调用对应接口的容错逻辑,fallback指定的类必须实现@FeignClient标记的接口 package com.example.demofeignclient.feign; ...
