[黑马头条]-项目整合网关

（1）建立一个网关微服务，在heima-leadnews-gateway导入以下依赖：

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>
    <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-nacos-config</artifactId>
        </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt</artifactId>
    </dependency>
</dependencies>

（2）在heima-leadnews-gateway下创建heima-leadnews-app-gateway微服务

引导类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient  //开启注册中心
public class AppGatewayApplication {

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

bootstrap.yml

server:
  port: 51601
spring:
  application:
    name: leadnews-app-gateway
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.200.130:8848
      config:
        server-addr: 192.168.200.130:8848
        file-extension: yml

在nacos的配置中心创建dataid为leadnews-app-gateway的yml配置：

代码如下：

spring:
  cloud:
    gateway:
      globalcors:
        add-to-simple-url-handler-mapping: true
        corsConfigurations:
          '[/**]':
            allowedHeaders: "*"
            allowedOrigins: "*"
            allowedMethods:
              - GET
              - POST
              - DELETE
              - PUT
              - OPTION
      routes:
        # 平台管理
        - id: user
          uri: lb://leadnews-user
          predicates:
            - Path=/user/**
          filters:
            - StripPrefix= 1

环境搭建完成以后，启动项目网关和用户两个服务，使用postman进行测试
