一个tomcat服务器发布两个项目服务

在一个tomcat服务器下发布两个web项目，启动报错

Web app root system property already set to different value: 'webapp.root' = [/home/user/tomcat/webapps/project1/] instead of [/home/user/tomcat/webapps/project2/] - Choose unique values for the 'webAppRootKey' context-param in your web.xml files! 

配置项目2中web.xml 加入

 <context-param> <param-name>webAppRootKey</param-name> <param-value>project2.root</param-value> </context-param>
