三: Gateway HelloWorld快速入门

Gateway HelloWorld快速入门

　　我们搞两个服务，分别是product产品服务项目，以及order订单服务项目，我们搞个小案例，搞一个网关，统一对path请求地址进行管理；

 

 一:  gateway-server 配置

 

gateway依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>

 

application.yml配置：

server:
  port: 80
  servlet:
    context-path: /

spring:
  application:
    name: gateway-server
  cloud:
    gateway:
      routes:  # 路由规则定义
       - id: product-service  # 路由ID
         uri: http://localhost:8080/ # 路由地址
         predicates:  # 断言规则
          - Path=/product/**

       - id: order-service  # 路由ID
         uri: http://localhost:8081/ # 路由地址
         predicates:  # 断言规则
          - Path=/order/**

 

启动类:

@SpringBootApplication
public class GatewayServerApplication {

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

}

 

 

二: product-demo 服务

application.yml

server:
  port: 8080
  servlet:
    context-path: /

spring:
  application:
    name: product-demo

 

测试接口:

@RestController
@RequestMapping("/product")
public class ProductController {

    @GetMapping("/{id}")
    public Product detail(@PathVariable("id")Integer id){
        return new Product(id,"xxx商品"+id,2,100.00);
    }

}

 

 

三:  order-demo 服务

application.yml配置:

server:
  port: 8081
  servlet:
    context-path: /

spring:
  application:
    name: order-demo

 

测试接口:

@RestController
@RequestMapping("/order")
public class OrderController {

    @GetMapping("/{id}")
    public Order detail(@PathVariable("id")Integer id){
        return new Order(id,"354324324",232.11,"用户信息"+id,"商品信息"+id);
    }
}

 

 

 

最终测试:

http://localhost:8001/order/2 和 http://localhost/order/2  一样的测试结果 ; 其他的类似
