windows端口占用和应用定位

问题：Error was Port already in use: 40001

1. netstat -ano|findstr "40001"

  TCP    127.0.0.1:14043        127.0.0.1:40001        CLOSE_WAIT      12644
  TCP    127.0.0.1:40001        0.0.0.0:0              LISTENING       15400
  TCP    127.0.0.1:40001        127.0.0.1:14043        FIN_WAIT_2      15400

 2. tasklist |findstr "15400"

Dict.exe                     15400 Console                    2     43,316 K

把dict.exe关掉就OK了。
