# 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″

# 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：

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

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
