补充：
想看具体详情的可以看我的github链接：codeking01/platform-parent: spring cloud整合spring boot、nacos、gateway、open feign等组件 (github.com)
由于我升级了jdk17，所以用上了spring boot 3.0.2了。
踩坑无数，一堆无用文章，写来写去，本文主要是提供给有基础的开发者再次快速搭建使用（确定版本）
如果你是要使用spring官方的一套，本文不太适用，参考这个：https://start.spring.io/
如果是 **阿里巴巴那一套，**本文是可以的，记住两个很重要的网址：
1.版本说明 · alibaba/spring-cloud-alibaba Wiki (github.com)
2.Cloud Native App Initializer (aliyun.com)
推荐从第二个进去，需要什么就选择什么，然后再将里面的版本号复制出来就行。
我目前搭建的版本是：
spring boot 2.6.13
XML
<spring-boot.version>2.6.13</spring-boot.version>
<spring-cloud-alibaba.version>2021.0.5.0</spring-cloud-alibaba.version>
<spring-cloud.version>2021.0.5</spring-cloud.version>几个需要注意的点，如果是想要配置网关的时候，需要使用使用 `lb:服务名称`
比如：
XML
routes:
- id: service-login
uri: lb://service-login
predicates:
- Path=/admin/**那么需要记得引入：
XML
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>整体的pom文件如下：

这个远程调用的时候，需要使用异步非阻塞，我写的如下：
两种都可以
java
package outfox.ead.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import outfox.ead.LoginFeignClient;
import java.util.concurrent.CompletableFuture;
@RestController
@RequestMapping("/kolPlatform")
public class userController {
@Autowired
private LoginFeignClient loginFeignClient;
@RequestMapping("/kol-platform/login")
public void getLogin(){
//loginFeignClient.getLogin();
System.out.println("kol-platform Login~~~~~~~~~~~");
//CompletableFuture.supplyAsync(() -> {
// loginFeignClient.getLogin();
// return null;
//});
CompletableFuture.runAsync(loginFeignClient::getLogin);
}
}
