新手建站工具温州做外贸网站设计

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

<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：

      routes:- id: service-loginuri: lb://service-loginpredicates:- Path=/admin/**

那么需要记得引入：

        <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-loadbalancer</artifactId></dependency>

整体的pom文件如下：

需要注意： 

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

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 {@Autowiredprivate 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);}}
