我目前正在使用非描述性文件名（例如kejr09238u30sdkfh.jpg）在我的网站上使用图片。出于SEO原因，我将这些图像重命名为descriptive-file-name.jpg。
目前已重命名6张图片。
如何编写301重定向？
示例
mysite.com/images/123.jpg 重命名为 mysite.com/images/abc.jpg
你能帮帮我吗？

使用简单的public class MyXMPP {
public MyXMPP(MyService context, String serverAdress, String logiUser,
String passwordser) {
this.serverAddress = serverAdress;
this.loginUser = logiUser;
this.passwordUser = passwordser;
this.context = context;
this.applicationContext = context;
init();
}
public static MyXMPP getInstance(MyService context, String server,String user, String pass) {
if (instance == null) {
instance = new MyXMPP(context, server, user, pass);
instanceCreated = true;
}
return instance;
}
public org.jivesoftware.smack.chat.Chat Mychat;
ChatManagerListenerImpl mChatManagerListener;
MMessageListener mMessageListener;
static {
try {
Class.forName("org.jivesoftware.smack.ReconnectionManager");

XMPPConnectionListener connectionListener = new XMPPConnectionListener();
connection.addConnectionListener(connectionListener);
}
private class ChatManagerListenerImpl implements ChatManagerListener {

}

/* Its work good for one to one chat */
private class MMessageListener implements ChatMessageListener {

@Override

命令：
redirect
