本文介绍Java程序实现Apache动态配置域名，希望对于初学Apache服务器相关的朋友有帮助，更多Apache安装、配置、报错处理等资源请本站内搜索。
1 配本机域名
C:/WINDOWS/system32/drivers/etc下hosts
127.0.0.1 localhost
127.0.0.1 www.a.com
127.0.0.1 www.b.com
127.0.0.1 www.c.com
2.配apache
C:/Program Files/Apache Software Foundation/Apache2.2/conf/extra下httpd-vhosts.conf（注意去掉httpd.conf加载httpd-vhosts.conf的#）。httpd.conf中加上NameVirtualHost *:80 （这里是一个ip多域名配置）
#begin-www.a.com
<VirtualHost *:80>
ServerName www.a.com
ServerAlias domain.tld *.domain.tld
DocumentRoot D:/a
<Directory "D:/a/">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
#end-www.a.com
#begin-www.b.com
<VirtualHost *:80>
ServerName www.b.com
DocumentRoot D:/b
<Directory "D:/b/">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
#end-www.b.com
3.写重启apache的.bat文件（我放c:/1.bat）
@echo on
c:
cd C:/Program Files/Apache Software Foundation/Apache2.2/bin
httpd -k restart
exit
4.动态添加域名的java类
import java.io.IOException;
import java.io.RandomAccessFile;
public class Example
{
/**
* @param args
*/
public static void main(String[] args)
{
try
{
RandomAccessFile file = new RandomAccessFile("C://Program Files//Apache Software Foundation//Apache2.2//conf//extra//httpd-vhosts.conf", "rw");
long filePoint = 0;
long fileLength = file.length();
String str = "#begin-www.c.com"
+ "/r/n"
+ "<VirtualHost *:80>"
+ "/r/n"
+ "ServerName www.c.com"
+ "/r/n"
+ "DocumentRoot D:/c"
+ "/r/n"
+ "<Directory /"D:/c//">"
+ "/r/n"
+ "AllowOverride None"
+ "/r/n"
+ "Options None"
+ "/r/n"
+ "Order allow,deny"
+ "/r/n"
+ "Allow from all"
+ "/r/n"
+ "</Directory>"
+ "/r/n"
+ "</VirtualHost>"
+ "/r/n"
+ "#end-www.c.com";
while (filePoint < fileLength)
{
String s = file.readLine();
if (s.startsWith("<VirtualHost"))
{
System.out.println(filePoint + "----------------------" + s);
}
filePoint = file.getFilePointer();
}
file.writeBytes(str);
file.close();
} catch (Exception e)
{
}
Runtime runtime = Runtime.getRuntime();
try
{
runtime.exec("cmd /C start C://1.bat");
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
5.删除域名的java类（更改，先删除后增加）
package com.cn.apche;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.RandomAccessFile;
import org.apache.commons.digester.Digester;
public class Bo {
public static void main(String[] args) {
String filepath = "C://Program Files//Apache Software Foundation//Apache2.2//conf//extra//httpd-vhosts.conf";
StringBuffer buf = new StringBuffer();
try{
RandomAccessFile file=new RandomAccessFile(filepath,"rw");
long filePoint=0;
long fileLength=file.length();
long [] point ;
String str = "<VirtualHost *:80>"+"/r/n"+
"ServerName www.d.com"+"/r/n"+
"DocumentRoot D:/d"+"/r/n"+
"<Directory /"D:/d//">"+"/r/n"+
"AllowOverride None"+"/r/n"+
"Options None"+"/r/n"+
"Order allow,deny"+"/r/n"+
"Allow from all"+"/r/n"+
"</Directory>"+"/r/n"+
"</VirtualHost>";
point = search("www.c.com",filepath);
if((point[1]-point[0])>0)
while(filePoint<fileLength)
{
String s=file.readLine();
if(point[0]<=filePoint&&filePoint<=point[1])
{
s ="";
System.out.println(filePoint+"----------------------"+s);
}
filePoint=file.getFilePointer();
buf.append(s+"/r/n");
}
// file.writeBytes(str);
file.close();
}
catch(Exception e){}
File file = new File(filepath);
if(file.exists()) file.delete();
try {
RandomAccessFile mm = new RandomAccessFile(filepath, "rw");
mm.writeBytes(buf.toString());
System.out.println("++++++++++++++++--------"+buf.toString());
mm.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static long[] search(String name,String path){
long start=0;
long end=0;
long result[]=new long[]{0,0};
try{
RandomAccessFile file=new RandomAccessFile(path,"rw");
long filePoint=0;
long fileLength=file.length();
while(filePoint<fileLength)
{
String s=file.readLine();
if(s.startsWith("#begin-"+name))
{
start =filePoint;
// System.out.println(filePoint+"----------------------"+s);
}
if(s.startsWith("#end-"+name))
{
end =file.getFilePointer();
//System.out.println(filePoint+"----------------------"+s);
}
filePoint=file.getFilePointer();
}
file.close();
}
catch(Exception e){}
result[0] = start;
result[1] = end;
return result;
}
}
