因無域名解析服務(wù)器,所以在hosts上配,來模擬dns解析.

10.1.1.241  localhost           指向gg文件夾
10.1.1.241  localhost.com       指向gg文件夾
10.1.1.241  one.localhost       指向a文件夾
10.1.1.241  one.localhost.com   指向a文件夾
10.1.1.241  two.localhost       指向b文件夾
10.1.1.241  two.localhost.com   指向b文件夾

經(jīng)過多方面嘗試,終于在tomcat下配置成功了.
