eclipse tomcat默认启动timeout时间太短，导致项目启动时间一长，就报错

工作空间workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 

<servers> 

<server auto-publish-setting="2" auto-publish-time="1" configuration-id="/Servers/Tomcat v7.0 Server   

at localhost-config" deployDir="wtpwebapps" hostname="localhost" id="Tomcat v7.0 Server at localhost"   

name="Tomcat v7.0 Server at localhost" runtime-id="Apache Tomcat v7.0" server-  

type="org.eclipse.jst.server.tomcat.70" server-type-id="org.eclipse.jst.server.tomcat.70" start-  

timeout="10000" stop-timeout="10000" testEnvironment="true" timestamp="0"/>  //设置

</servers> 

设置好之后 restart eclipse
