服务工程结构

添加依赖

在leadnews-gateway模块中添加网关依赖：

pom.xml

<dependencies>
    <!-- gateway -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>
    <!-- nacos -->
    <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>
    <!-- jwt -->
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-api</artifactId>
    </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-impl</artifactId>
    </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-jackson</artifactId>
    </dependency>
</dependencies>

完善工程

删除leadnews-gateway下的src目录，创建leadnews-app-gateway子模块

子模块的src下创建包com.swx.app.gateway

创建启动类

AppGatewayApplication

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

配置文件

在resources下创建bootstrap.yaml

bootstrap.yaml

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

其他配置信息使用Nacos配置中心配置，配置完成点击发布即可

spring:
  cloud:
    gateway:
      globalcors:
        cors-configurations:
          '[/**]': # 匹配所有请求
            allowedOrigins: '*' # 跨域处理，允许所有的域
            allowedMethods: # 支持的方法
              - GET
              - POST
              - PUT
              - DELETE
      routes: 
        - id: user
          uri: lb://leadnews-user
          predicates:
            - Path=/user/**
          filters:
            - StripPrefix= 1

启动项目

启动AppGatewayApplication网关服务

使用接口测试工具访问：

http://localhost:51601/user/api/v1/login/login_auth

51601：是配置的网关端口
/user：是配置的网关前缀，路由时会去掉该前缀
