Zuul 相当于是设备和 Netflix 流应用的 Web 网站后端所有请求的前门，提供动态路由，监控，弹性，安全等的边缘服务
所有请求都经过网关（API Gateway）zuul，然后转发到各个子服务上去
1.注册中心eureka
<!--eureka--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency>
@EnableEurekaServer//注解启动一个服务注册中心 @SpringBootApplication public class EurekaApp { public static void main(String[] args) { SpringApplication.run(EurekaApp.class, args); } }
#application配置 server.port=8888 #在默认设置下，该服务注册中心也会将自己作为客户端来尝试注册它自己，所以我们需要禁用它的客户端注册行为 eureka.client.register-with-eureka=false eureka.client.fetch-registry=false #服务注册地址 eureka.instance.ip-address=localhost eureka.instance.prefer-ip-address=true eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/
启动app，访问http://localhost:8888/
2.service1
@EnableDiscoveryClient//激活Eureka中的DiscoveryClient实现 @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 #注册中心地址 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 被调用， 请求地址：" + request.getRequestURI(); } }
3.service2
@EnableDiscoveryClient//激活Eureka中的DiscoveryClient实现 @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 #注册中心地址 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 被调用， 请求地址：" + request.getRequestURI(); } }
4.zuul网关
<!--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//声明zuul代理 @SpringBootApplication public class ZuulMainApp { public static void main(String[] args) { SpringApplication.run(ZuulMainApp.class, args); } }
#注册中心地址 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 #注册服务 zuul.routes.service1.path=/service1/** zuul.routes.service1.serviceId=service1 zuul.routes.service2.path=/service2/** zuul.routes.service2.serviceId=service2
测试：启动sevice1，service2，zuul
查看注册中心：
通过网关+路由名称访问：
http://localhost:8080/baidu
http://localhost:8080/service1/index
http://localhost:8080/service2/index
