Server Tomcat v7.0 Server at localhost was unable to start within 45 seconds -----》myeclipse2015

错误：Server Tomcat v7.0 Server at localhost was unable to start within 45 seconds

错误提示就是我们限定了部署的时间导致的错误。

修改 workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件。
把其中的start-timeout="45" 改为 start-timeout="100" 或者更长，根据不同同学的工程大小来设置。
