一、網關模塊搭建
1. 引入依賴
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<spring.cloud-version>Hoxton.SR9</spring.cloud-version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<!--https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E-->
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring.cloud-version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
2. 配置
訪問??product.gblfy.com**???就會路由到??http://localhost:9000?? 這里的9000端口我們的產品服務模塊
server:
port: 8081
spring:
cloud:
gateway:
routes:
- id: product
uri: http://localhost:9000
predicates:
- Host=product.gblfy.com**
3. 啟動類
package com.gblfy.gatewayserv;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class GatewayServApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayServApplication.class, args);
}
}
二、產品服務模塊搭建
2.1. 引入依賴
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--服務注冊發現-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<!--spring-cloud-alibaba 版本控制-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>2.2.6.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
2.2. 配置
server:
port: 9000
management:
endpoints:
web:
exposure:
include: '*'
2.3. 控制層
package com.gblfy.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ProductController {
//http://localhost:9000/product/" + productId
@GetMapping("/product/{productId}")
public String getProductName(@PathVariable Integer productId) {
return "IPhone 12";
}
}
2.4. 啟動類
package com.gblfy;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ProductAplication {
public static void main(String[] args) {
SpringApplication.run(ProductAplication.class);
}
}
2.5. 啟動產品模塊
三、啟動中間件
3.1. nacos啟動
3.2. 啟動gateway
3.3. 配置域名映射
四、測試驗證
4.1. 測試產品服務
??http://localhost:9000/product/1??
4.2. 網關訪問產品
通過網關gateway訪問產品模塊服務
??http://product.gblfy.com:8081/product/1??
