eclipse - spring 工具套件 spring mvc 项目 - 创建后的 22 个问题

Question

所以，我下载并安装了 STS，然后我创建了一个新的 Spring MVC 项目。紧接着，sts 提醒我关于 22 个问题，它们是:

我该如何解决这个问题？谢谢

第一次新建STS项目的时候也遇到了很多错误。这似乎只有在我没有任何 Maven 存储库或之前没有启动/使用 Maven 时才会发生。就我而言，我通过从命令行手动启动 Maven 命令来解决这个问题。尝试 'cd' 到包含 pom.xml 的项目目录并调用 mvn来自那里的STS。

   cd c:\users\name\sts-projects\projectname
   c:\programs\springsource\apache-maven-3.0.3\bin\mvn compile

然后，打开 STS，右键单击项目名称，选择“Maven”、“更新项目...” 选择“强制更新快照/发布”。不要选择“离线”。
