springcloud+zuul初尝试_enablediscoveryclient zuul-优快云博客

本文链接：https://blog.youkuaiyun.com/leijie0322/article/details/121707800

本文档介绍了如何在Spring Cloud框架下配置和使用Zuul作为微服务网关。示例展示了Zuul与Eureka、Consumer和Provider服务的集成，以及如何通过Zuul路由请求。启动Zuul后，可以成功路由到Consumer和Provider的服务接口，实现了简单的API网关功能。

在微服务架构中经常遇到的另一个组件，springcloud中的zuul网关。
在上篇文章的基础上，一共4个微服务工程，分别为eureka服务注册与发现、zuul网关、consumer服务、provider服务

3启动类

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class ZuulApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication.class, args);
    }

}

2application.properties


spring.application.name=consumer
server.port=9004

#使用IP注册
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.cloud.client.ip-address}:${server.port}
eureka.client.service-url.defaultZone=http://localhost:9001/eureka/

3启动类

@SpringBootApplication
@EnableDiscoveryClient
public class ConsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }

}

4提供的接口

@RestController
@RequestMapping("/rest1")
public class DemoController {

    @RequestMapping("/hello")
    private String hello() {
        return "this is consumer";
    }
}

provider实例
1依赖同consumer
2application.properties与consumer同理
3启动类与consumer同理
4提供的接口与consumer同理
测试
依次启动eureka（9001）、zuul（9003）、consumer（9004）、provider（9005）
访问eureka如下
在这里插入图片描述
1访问consumer自己的接口如下

2访问provider自己的接口如下

3通过zuul路由到consumer服务的接口如下

4通过zuul路由到provider服务的接口如下

已完成zuul的简单配置，欢迎高级配置玩法交流。
