SpringCloudGateway 服务网关基础搭建

1. 依赖

<!-- 服务发现 -->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!-- 服务网关 -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>

2. 配置

spring:
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
    gateway:
      globalcors:
        corsConfigurations:
          '[/**]':
            allowedOrigins: '*'
            allowedHeaders: '*'
            allowedMethods: '*'
            allowCredentials: true
      discovery:
        locator:
          enabled: true
          lowerCaseServiceId: true

3. 启动类

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

4. 注意

• 如果服务已经启用CORS过滤器，则无需再gateway上配置CORS否则会导致错误
• 使用nacos做服务注册中心时，服务必须与gateway注册在同一个名空间以及分组下，才会被自动发现定位。
