(1). 环境准备工作

  1. eureka注册中心(1111/2222).
  2. 服务提供者(TEST-PROVIDER:8080).
  3. 服务消费者(TEST-CONSUMER-FEIGN:7070).
  4. 项目之间的依赖:TEST-CONSUMER-FEIGN–> TEST-PROVIDER.
  5. 测试:curl http://localhost:7070/consumer

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

@SpringBootConfiguration
@EnableAutoConfiguration
public class Application {
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

(5). 访问代理服务器

目标:访问代理服务器(9000),它能正确解析到后面的微服上(7000).
http://localhost:9000/consumer

"spring cloud gateway proxy consumer"
