springboot12-zuul

Zuul 相當於是設備和 Netflix 流應用的 Web 網站后端所有請求的前門，提供動態路由，監控，彈性，安全等的邊緣服務

 

所有請求都經過網關（API Gateway）zuul，然后轉發到各個子服務上去

 

 

1.注冊中心eureka

<!--eureka-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>

@EnableEurekaServer//注解啟動一個服務注冊中心
@SpringBootApplication
public class EurekaApp {

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

#application配置
server.port=8888

#在默認設置下，該服務注冊中心也會將自己作為客戶端來嘗試注冊它自己，所以我們需要禁用它的客戶端注冊行為
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

#服務注冊地址
eureka.instance.ip-address=localhost
eureka.instance.prefer-ip-address=true
eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/

啟動app，訪問http://localhost:8888/

2.service1

@EnableDiscoveryClient//激活Eureka中的DiscoveryClient實現
@SpringBootApplication
public class Service1App {

    public static void main(String[] args) {
        SpringApplication.run(Service1App.class, args);
    }
}

server.port=1111
server.address=localhost
spring.application.name=service1

#注冊中心地址
eureka.instance.ip-address=localhost
eureka.instance.prefer-ip-address=true
eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/

public class UserController {

    private final static Logger LOGGER = LoggerFactory.getLogger(User2Controller.class);
    @Autowired
    private DiscoveryClient discoveryClient;

    @RequestMapping("/index")
    public String index(HttpServletRequest request){
        return "service1 被調用， 請求地址：" + request.getRequestURI();
    }

}

 

3.service2

@EnableDiscoveryClient//激活Eureka中的DiscoveryClient實現
@SpringBootApplication
public class Service2App {

    public static void main(String[] args) {
        SpringApplication.run(Service2App.class, args);
    }
}

server.port=2222
server.address=localhost
spring.application.name=service2

#注冊中心地址
eureka.instance.ip-address=localhost
eureka.instance.prefer-ip-address=true
eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/

public class User2Controller {

    private final static Logger LOGGER = LoggerFactory.getLogger(User2Controller.class);
    @Autowired
    private DiscoveryClient discoveryClient;

    @RequestMapping("/index")
    public String index(HttpServletRequest request){
        return "service2 被調用， 請求地址：" + request.getRequestURI();
    }

}

 

 4.zuul網關

<!--eureka-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zuul</artifactId>
        </dependency>

@EnableZuulProxy//聲明zuul代理
@SpringBootApplication
public class ZuulMainApp {

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

#注冊中心地址
eureka.instance.ip-address=localhost
eureka.instance.prefer-ip-address=true
eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/

#路由配置
#url形式
zuul.routes.baidu.path=/baidu/**
zuul.routes.baidu.url=http://www.baidu.com
#注冊服務
zuul.routes.service1.path=/service1/**
zuul.routes.service1.serviceId=service1
zuul.routes.service2.path=/service2/**
zuul.routes.service2.serviceId=service2

 

測試：啟動sevice1，service2，zuul

查看注冊中心：

通過網關+路由名稱訪問：

http://localhost:8080/baidu

http://localhost:8080/service1/index

http://localhost:8080/service2/index
