tomcat免重启
　　1、打开eclipse中的tomcat，点击Arguments，在VM arguments：配置如下
　　-noverify -javaagent:D:\softbak\jar\jrebel4.0.2\jrebel.jar    //下载一个jrebeljar包
　　-Drebel.dirs=D:\eclipse-   workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\项目名称\WEB-INF\classes    //目录指向项目的classes底下
　　-Drebel.spring_plugin=true     //如果有spring插件则为true
　　-Drebel.struts2-plugin=true    //如果有struts2插件则为true
　　-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=下面是默认的-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=
　　-Dcatalina.base="D:\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1" -Dcatalina.home="D:\eclipse-workspace\apache-tomcat-6.0.24" -Dwtp.deploy="D:\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps" -Djava.endorsed.dirs="D:\eclipse-workspace\apache-tomcat-6.0.24\endorsed"
　　去掉项目名访问：

1、tomcat6.0：<Host></Host>间加了一句<Context path="" docBase="/fts" debug="0" reloadable="true"/>
2、tomcat7.0 <Host></Host>间加了一句<Context path="/" docBase="fts" debug="0" reloadable="true"/>

<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />这句话注意了，某些版本中没有这句话，tomcat7版本里面有，他注意是防止threadLocal内存泄漏。之前版本使用

Other threads may be stopped with theclearReferencesStopThreads flag, but it's unsafe.	Fix the application to stop the thread when the application is stopped
