我们在启动Tomcat的时候，经常会报这种错误：
Server MyEclipse Tomcat v7.0 was unable to start within 45 seconds. If the server requires more time
翻译为：
MyEclipse 的tomcat不能再45秒内启动服务。服务器需要更长的时间；
那么，我们就将Tomcat启动的值设置成更长的时间：
1.我们在MyEclipse工作目录中找到：workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件。
2.把其中的start-timeout="45" 改为 start-timeout="450" 或者更长，根据工程大小来设置。
代码如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<servers><server DRIVER_CREATED_2="true" HOME_DIR="C:/Users/user/.myeclipse/derby" PORT="1527" derby_autostart_timeout="3000" derby_enable_autostart="true" hostname="localhost" id="com.genuitec.derby.server" id-set="true" me-disable-overview-page="true" name="MyEclipse Derby" server-type="com.genuitec.derby.server" server-type-id="com.genuitec.derby.server" single-instance="true" start-timeout="240" stop-timeout="240" timestamp="0"/><server auto-publish-setting="2" auto-publish-time="1" configuration-id="/Servers/MyEclipse Tomcat v7.0-config" deployDir="wtpwebapps" has-configuration="true" hostname="localhost" id="com.genuitec.embedded.tomcat.server.v70" id-set="true" java-location="D:\MyEclipse 2016 CI\binary\com.sun.java.jdk8.win32.x86_64_1.8.0.u66" name="MyEclipse Tomcat v7.0" runtime-id="com.genuitec.embedded.tomcat.runtime.v70" server-location="D:\MyEclipse 2016 CI\plugins\com.genuitec.eclipse.server.embedded.tomcat.core_13.0.0.me201602031002\tomcat70" server-type="com.genuitec.embedded.tomcat.server.v70" server-type-id="com.genuitec.embedded.tomcat.server.v70" single-instance="true" start-timeout="450" stop-timeout="15" testEnvironment="false" timestamp="1" useAutoDeploy="true"><list key="modules" value0="OneMuWe::org.eclipse.jst.jee.server:OneMuWe::jst.web::3.0%%EXPLODED"/></server>
</servers>
3.重启MyEclipse。
这样问题就完美的解决了。
