解决：在本地仓库中找不到e3mall-common:jar包  解决：将e3mall-common安装到本地仓库

2.在启动e3-manager-service时，程序卡在starting Apache Tomcat/7.0.47不动

解决：将log4j放入service下的resources下，即可查看程序运行出错的信息

    我的问题是未开zookeeper，在cmd中运行zkServer.cmd后，重新启动maven即可成功

3.maven可以启动成功，访问localhost:8080可以成功，但当访问localhost:8080/item/873970，即查找数据库时，出现500错误

解决：将e3-manager; e3-manager-service; e3-manager-web进行maven-install，重新运行，即可成功。

4.启动e3-manager或者e3-manager-web时，系统在启动端口时卡住不动，如下图

解决：想要获取错误信息，可将log4j.properties放在e3-manager的resources下面，即可看到错误信息

5.启动时显示报错“clean plugin”错误，一般是eclipse异常退出，导致javaw.exe在后台继续运行

解决：任务管理器关闭javaw.exe进程，重新运行
