示例GitHub源码地址:https://github.com/AngelSXD/springcloud 1.首先使用feign调用,需要配置熔断器 2.配置熔断器需要将熔断器注入Bean,熔断器类上需要加注解@Component,确保可以被spring扫描到 3.熔断器类需要实现feignClient接口,并且重写 feignClient接口中的所有方法,做降级处理逻辑 4.需要在feignClient上的注解中,通过fallback属性来指明熔断器.class,等服务熔断的时候,来执行熔断器…

1.问题的发生 Feign在默认情况下使用的是JDK原生的URLConnection发送HTTP请求,没有连接池,但是对每个地址会保持一个长连接,即利用HTTP的persistence connection .我们可以用Apache的HTTP Client替换Feign原始的http client, 从而获取连接池.超时时间等与性能息息相关的控制能力.Spring Cloud从Brixtion.SR5版本开始支持这种替换,首先在项目中声明Apache HTTP Client和feign-http…
