创建网关微服务
添加依赖
修改 gateway 服务的 pom.xml

创建 gateway 启动类
/**
* @author BNTang
*/
@SpringBootApplication
@EnableDiscoveryClient
public class GateWayApplication {
public static void main(String[] args) {
SpringApplication.run(GateWayApplication.class, args);
}
}
在 resources 当中创建配置文件 application.yml
logging:
pattern:
console: "%d{HH:mm:ss.SSS} %clr(%5p) %clr(-){faint} %clr(%-80.80logger{79}){cyan} %clr(:) %m%n"
server:
port: 9000
spring:
application:
# 此实例注册到服务端的name
name: gateway
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
discovery:
locator:
enabled: true
routes:
- id: service-video
uri: lb://service-video
predicates:
- Path=/service_video/**
- id: service-vod
uri: lb://service-vod
predicates:
- Path=/service_vod/**
- id: service-upload
uri: lb://service-upload
predicates:
- Path=/service_upload/**
在 gateway 当中添加跨域配置处理如下, 创建 config 包, 在该包下创建跨域处理配置
/**
* @author BNTang
*/
@Configuration
public class CorsConfig {
@Bean
public CorsWebFilter corsFilter() {
CorsConfiguration config = new CorsConfiguration();
config.addAllowedMethod("*");
config.addAllowedOrigin("*");
config.addAllowedHeader("*");
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
source.registerCorsConfiguration("/**", config);
return new CorsWebFilter(source);
}
}
取消控制器上的跨域注解, 把前端请求地址改成网关请求地址如下图，Controller 跨域注解全部去除
修改前端为 gateway 请求地址
