mall商城微服务遇见的坑

【报错】

• 使用nacos导入配置文件报错：未读取到合法数据，请检查导入的数据文件。

【原因】

• 对比在naocs server中导出的文件，发现是少了一级目录。需要创建一个文件夹，名称为组的名称。
• 因为在nacos上传文件时是可以选择命名空间的，但是不会选择组，所以nacos server识别报错了。

【解决】

• 创建文件夹，命名为DEFAULT_GROUP，然后将配置文件放进去，打包上传成功。
• 将修改的配置文件压缩成zip文件——上传配置文件。

【解决】

• 创建habor仓库，配置http模式。
• docker加入harbor仓库认证.。
• 服务器登录harbor仓库成功。
• 修改pom.xml中仓库地址为：http://192.168.4.119:2375。
• 执行行mvn clean package docker:build。
• 确认生成镜像并且已经上传到仓库。
