# 服务降级: 站在系统整体负荷角度 实现: 关闭系统中某些边缘服务 保证系统核心服务运行
Emps 核心服务 Depts 边缘服务
# 1.客户端openfeign + hystrix实现服务降级实现
- 引入hystrix依赖
- 配置文件开启feign支持hystrix
- 在feign客户端调用加入fallback指定降级处理
- 开发降级处理方法# 2.开启openfeign支持服务降级feign.hystrix.enabled=true #开启openfeign支持降级# 3.在openfeign客户端中加如Hystrix@FeignClient(value = "PRODUCTS",fallback = ProductFallBack.class)
public interface ProductClient {
@GetMapping("/product/hystrix")
String testHystrix(@RequestParam("name") String name);
}# 4.开发fallback处理类public class ProductFallBack implements ProductClient {
@Override
public String testHystrix(String name) {
return "我是客户端的Hystrix服务实现!!!";
}
