所以,我下载并安装了STS,然后我创建了一个新的Spring MVC项目.在那之后,sts提醒我22个问题,这里是:

我该如何解决这个问题？谢谢

第一次创建新的STS项目时,我也遇到了很多错误.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.在我的例子中,我通过手动从命令行启动Maven命令来解决这个问题.尝试'cd'到包含的项目目录pom.xml并mvn从那里调用STS附带的.

   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/版本".不要选择"离线".
