1.加入eureka-client和zuul啟動器

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
</dependency>

2.添加application.yml相關(guān)配置

server:
  port: 10010
spring:
  application:
    name: xxxx-gateway
eureka:
  client:
    service-url:
      defaultZone: http://localhost:10086/eureka
    registry-fetch-interval-seconds: 5
zuul:
  prefix: /api
  routes:
    item-service: /item/** #路由到商品的微服務(wù)
    search-service: /search/** #路由到搜索微服務(wù)

3. 添加啟動類

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class GatewayApplication {

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

4. 用網(wǎng)關(guān)處理跨越相關(guān)請求

@Configuration
public class CorsConfiguration {

    @Bean
    public CorsFilter corsFilter() {

        // 初始化cors配置對象
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        // 允許跨域的域名,如果要攜帶cookie,不能寫*, *代表所有域名都可以跨域訪問
        corsConfiguration.addAllowedOrigin("http://manage.xxxx.com");
        corsConfiguration.addAllowedOrigin("http://www.xxxx.com");
        corsConfiguration.setAllowCredentials(true); //設(shè)置是否允許攜帶cookie
        corsConfiguration.addAllowedMethod("*");  // 代表所有的請求方法, GET, POST, PUT, Delete
        corsConfiguration.addAllowedHeader("*");  // 允許攜帶任何頭信息

        // 初始化cors配置源對象
        UrlBasedCorsConfigurationSource configurationSource = new UrlBasedCorsConfigurationSource();
        configurationSource.registerCorsConfiguration("/**", corsConfiguration);

        // 返回corsFilter實(shí)例, 參數(shù): cors配置源對象
        return new CorsFilter(configurationSource);
    }
}
