主要是因为 1.此tomcat不支持修改host的name属性，必须修改为原属性
2.修改之后需要右键STS-tomcat，找到browse Devlopment选项，进而找到tomcat的conf/server.xml，修改成与项目视图中的server.xml一样内存
如果都不行，删除tomcat，删除G:\sts\workspacemy\.metadata\.plugins\org.eclipse.wst.server.core\路径下除publish.xml外的文件（或都删了，未试）
，再重新安装
另此路径也关键：G:\sts\workspacemy\.metadata\.plugins\org.eclipse.wst.server.core
