lamp-gateway-server模块启动报错

[flag-bug]

版本信息：

JDK 版本(必填) : 1.8.x
源码版本(必填)：3.0.2
MySQL(必填)： 8.0.21
Nacos(必填)：1.3.2

问题描述：

已使用maven helper工具查看依赖，没有spring-webmvc依赖，lamp-gateway-server.yml中配置了lamp.webmvc.enabled=false，如你所说在lamp-boot-util中GlobalMvcConfigurer实现了WebMvcConfigurer，但依赖lamp-boot-util已经排除了spring-webmvc依赖，还要怎么排除GlobalMvcConfigurer？报错中是LampRabbitMqConfiguration$RabbitMqConfiguration，这里面没有发现有关springmvc的东西？

重现步骤

1. nacos、redis、rabbitmq正常启动部署了，nacos中关于mysql、redis、rabbitmq的配置已经修改为和本地一致
2. lamp-util 3.0.2正常install
3. 启动lamp-gateway-server，报错！

参考： #45

[flag-bug]

没有自建服务，这是lamp源码没有改动的

[zuihou]

1. 建议认真阅读文档 快速启动 章节。
   https://www.kancloud.cn/zuihou/zuihou-admin-cloud/1284756

2. 认真理解和观察常见报错：
   (lamp-gateway-server)zuihou-gateway-server 模块启动报错 #57
   启动报错: class path resource [com/github/zuihou/mq/MyRabbitMqConfiguration$RabbitMqConfiguration.clss] #45

3. 对比nacos中 lamp-gateway-server.yml 的内容和 lamp-cloud/01-third-party/nacos/clientConfig/lamp-gateway-server.yml的内容

好的，谢谢，问题已解决！

[zuihou]

麻烦回复下解决方案

[flag-bug]

因为我的nacos导入配置没有注意命名空间，所以没有获取到nacos配置

[flag-bug]

项目中用的Apollo，第一次用nacos，所以犯了这么简单的错误

[flag-bug]

还是没有认真看文档，如果认真看了文档就不会瞎弄半天，百思不得其解
