javaweb乱码处理

String str = new String(request.getParameter("参数名").getBytes("iso-8859-1"), "utf-8");

如果需要上述代码才能获取到正常的编码,可能是本地与服务器上的Tomcat配置不一样导致的,修改server.xml的 URIEncoding=”UTF-8″

 <Connector port="8080" protocol="HTTP/1.1"
          connectionTimeout="20000"
           redirectPort="8443"/>

 <Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" URIEncoding="UTF-8"/>

javaWeb cannot be resolved to a type

如果出现这个bug,它说明类找不到,如果代码没有报错,编译通过,bug任然出现,此时你可以clean工程,在运行。

centos wifi

dmesg | grep firmware(看看有没有来自无线网卡的固件请求)

iw:

 eeeww

 iw dev(查找无线网卡口)

 iw wls1 link(查看wls1网口无线网络连接情况)

 iw wls1 scan | grep SSID(查看wls1网口可连接的wifi)

ip:

 ip link set wls1 up(将无线网口wls1开启)

 ip link show wls1(显示无线网口wls1连接情况)

 ip addr  show wls1(显示分配的ip地址,特别适用于查看是否成功地通过dhcp自动获取了ip地址)

wpa_supplican:

 wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase "ssid" "psk") (连接无线网ssid,密码psk)

dhclient:

 dhclient wls1(为wls1分配ip地址)

centos java Web重新部署上传的文件会被删除问题

修改/tomcat/conf/web.xml

 <Context path="/attachment" docBase="F:\attachment" debug="0" reloadable="fasle" privilege="true" />

比如我将F盘的attachment文件夹作为上传文件存放目录,可以通过localhost/attachment去访问里面的内容
