補(bǔ)充：

想看具體詳情的可以看我的github鏈接：codeking01/platform-parent: spring cloud整合spring boot、nacos、gateway、open feign等組件 (github.com)

由于我升級(jí)了jdk17，所以用上了spring boot 3.0.2了。

踩坑無(wú)數(shù)，一堆無(wú)用文章，寫來(lái)寫去，本文主要是提供給有基礎(chǔ)的開(kāi)發(fā)者再次快速搭建使用（確定版本）

如果你是要使用spring官方的一套，本文不太適用，參考這個(gè)：https://start.spring.io/

如果是 阿里巴巴那一套，本文是可以的，記住兩個(gè)很重要的網(wǎng)址：?

1.版本說(shuō)明 · alibaba/spring-cloud-alibaba Wiki (github.com)

2.Cloud Native App Initializer (aliyun.com)

推薦從第二個(gè)進(jìn)去，需要什么就選擇什么，然后再將里面的版本號(hào)復(fù)制出來(lái)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>

幾個(gè)需要注意的點(diǎn)，如果是想要配置網(wǎng)關(guān)的時(shí)候，需要使用使用 `lb:服務(wù)名稱`

比如：

      routes:
        - id: service-login
          uri: lb://service-login
          predicates:
            - Path=/admin/**

那么需要記得引入：

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

需要注意：?

這個(gè)遠(yuǎn)程調(diào)用的時(shí)候，需要使用異步非阻塞，我寫的如下：

兩種都可以文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-665583.html

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);
    }

}

到了這里，關(guān)于spring cloud整合spring boot，整合nacos、gateway、open-feign等組件的文章就介紹完了。如果您還想了解更多內(nèi)容，請(qǐng)?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
