环境 : Nacos 2.2.1 , Spring-cloud Hoxton.SR1 , com.alibaba.cloud.version 2.2.8 (留意这个版本)
最近新搭建了一次虚拟机, 然后重新部署了Nacos , 同时也在一个新项目里引入了Nacos 的服务注册功能 , 以下是服务Pom版本管理配置
-

然后再实际使用模块pom文件中引入服务注册和配置管理
-
<dependencies>
-
<!-- Nacos依赖-->
-
<dependency>
-
<groupId>com.alibaba.cloud
</groupId>
-
<artifactId>spring-cloud-starter-alibaba-nacos-discovery

-
</dependency>
-
<!-- 在没有引入一下pom时候服务注册是正常的 -->
-
<dependency>
-
<groupId>com.alibaba.cloud
</groupId>
-
<artifactId>spring-cloud-starter-alibaba-nacos-config
</artifactId>
-
</dependency>
-
</dependencies>

application.ymal 的配置如下

此时启动项目问题就显露了 , 在没有加上 spring-cloud-starter-alibaba-nacos-config 这个maven配置的时候服务是可以正常启动的 , 然后加了之后 服务根本就启动不起来 , 报错如下

看表象 , 是Logback 引起的问题 , 初步怀疑是可能因为冲突了 , 因为我本地也使用了 Logback 的配置 , Logbak内容入如下

问题排查解决
问题原因大概猜测是因为配置冲突引起的, 我就去看jar的内容 , 看看是nacos 的那个pom 再用logback , 最终在 nacos-config -> nacos-client 2.1.0 中发现了Logback 的配置文件
罪魁祸首找到了 , 那么久来处理掉这个冲突 , 最直接最简洁的方式就是 , 直接在config 的pom 中屏蔽掉他的nacos-client

事实证明 , 无效,,,,,,, , 此路不通 ,,, 就换条路 , 去搜百度, 也是资料少的要死 , 索性直接去GitHub上找Nacos 仓库 找 issues , 抱着试一试的态度 , 万幸 , 找到了一个2022年6月份提交的一个bug
这个Issues 说得就是 nacos-logback 和 项目中的logback冲突 , 并且这位仁兄还放出了报错信息 , 看报错内容是不是眼熟 , 嗯哼 ? 拨云见"日"了 , 继续往下看 , 可以发现这就是一个 Nacos的Bug , 然后给出的临时解决方案就是 , 吧项目中的Logback 的 scan 属性 , set = false ;
然后再次重启项目 , 豁然 启动了 , 为什么这样就可以了呢 ??
<configuration>元素中的scan属性可以用来控制 logback 是否自动扫描配置文件的变化并重新加载配置。该属性的默认值是true，表示 logback 会周期性地检查配置文件的变化，并在检测到变化时重新加载配置文件。具体来说，
scan属性的原理是通过启动一个单独的线程来监视配置文件的变化，一旦检测到配置文件发生了变化，就会重新读取配置文件并更新 logback 的内部状态。这样可以避免在修改配置文件后需要手动重启应用程序的情况，从而提高开发效率。需要注意的是，如果您的配置文件较大，或者您的应用程序的日志记录量很大，那么频繁地重新加载配置文件可能会带来一定的性能开销。因此，在生产环境中建议将
scan属性设置为false，并在必要时手动重启应用程序以更新配置文件。
至此 , 问题算是临时性解决了 , 但是总让人感觉不满意, 总感觉是治标不治本 , nacos 高版本是否会解决这个问题呢 ?? 抱着好奇的态度 , 去 Mvn 中央仓库看看Nacos 的pom 版本 现在到那个版本了. ps: 我现在的项目使用的是 2.2.8 , 截止目前最新的版本是 2022.0.0.0-RC-1
从这里看 , client 的版本也更新了 ,
那么 , 试试呗, 升级项目中管理的 spring-cloud-alibaba-dependencies 版本 ,

</spring-cloud.version>
-
<!-- <com.alibaba.cloud.version>2.2.8.RELEASE</com.alibaba.cloud.version>-->

果不其然, 出问题了 ,,,,,,真 tm X蛋 , 最新版本的nacos pom 居然是 jdk 17 , 我以为我11 都够新的了 , ,,,,,,,,, 搞到这里 , 如果大家不想继续搞了的话, 就用前面的解决办法 , 把scan 设置为 false , ,,, 什么治标不治本 , 先启动再说 ,,,,爱咋滴咋滴,,,,,,有时间再搞 ,
挣扎10分钟 , 决定还是不让这篇文章烂尾 , 决心要处理下
重新打开 mvn 中央仓库 , 大丈夫能屈能伸 , 退而求其次 , 选个 使用量多的 , 低一版的 , 2021.1
好奇看了一眼 , 这个nacos-client到底咋回事 , 点进去一看, 豁.... 好家活,,,
废话少说 , pom 再一次换版本 ,
