springcloud+zuul初尝试

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
zuul工程实例

2application.properties

spring.application.name=zuul
server.port=9003

#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/

zuul.routes.comsumer.path=/rest1/**
zuul.routes.comsumer.service-id=consumer
zuul.routes.comsumer.strip-prefix=false
zuul.routes.provider.path=/rest2/**
zuul.routes.provider.service-id=provider
zuul.routes.provider.strip-prefix=false
zuul.host.connect-timeout-millis=60000
zuul.host.socket-timeout-millis=60000

3启动类

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class ZuulApplication {

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

}

consumer实例
1依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

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

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。
