警告: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:esignmanage' did not find a matching property.解决

1.开发环境：

　　环境：myeclipse2015+tomcat7+win10

2.异常：

　　偶尔在部署项目的时候回发现tomcat7部署后配置文件按照路径居然找不到自己的项目。httP://localhost:80，都无法访问。具体错误信息如下，在tomcat的配置文件server.xml中发现context标签内一切正常

　　<Context docBase="F:\Tomcat7.0\me-webapps\esignmanage" path="/esignmanage" reloadable="true" source="org.eclipse.jst.jee.server:esignmanage"/></Host>，然后通过查找其他配置文件，在tomcat7的conf->catalina->localhost中找到了对应当前项目的xml配置文件，其中context标签终于找到了异常所在。

<Context docBase="F:\Tomcat7.0\me-webapps\Tomcat7.0\me-webapps\esignmanage" path="/esignmanage" reloadable="true" source="org.eclipse.jst.jee.server:esignmanage"/>

，然后删除tomcat7下的work目录即可恢复。
