springcloud gateway网关
灰太狼_cxh 人气:01.项目目录：
创建项目gateway作为父类
2.代码实现：

创建module项目gateway-client
添加依赖

yml配置
server: port: 8002 spring: application: name: gateway-client #服务名 profiles: active: dev #环境设置 cloud: nacos: discovery: server-addr: 127.0.0.1:8848 #nacos服务注册
控制层
@RestController
public class ClientController {
@Value("${server.port}")
private String port;
@RequestMapping("/index")
public String index(){
return "gateway-client端口：" + port;
}
}启动类添加注解
@SpringBootApplication
@EnableDiscoveryClient
public class GatewayClientApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayClientApplication.class, args);
}
}创建module项目gateway-service
添加依赖

yml配置
server: port: 8001 spring: application: name: gateway-service #服务名 profiles: active: dev #环境设置 cloud: gateway: routes: # 透传服务 - id: gateway-client #设置路由id uri: lb://gateway-client #设置路由的url lb://nacos服务注册名称 predicates: - Path=/client/** #路径匹配规则 filters: - StripPrefix=1
跨域配置
@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);
}
}3.实现效果：
启动nacos后，再启动gateway-client, gateway-service项目，打开浏览器http://localhost:8001/client/index
返回信息：gateway-client端口：8002
