文件名为:template_style.css

 

#temoplate_root{
	width:331px;
	height:408px;
	background:url(../images1/top.jpg) no-repeat 0 0; 
	font-size:12px;
	border:1px solid #686868;
}
#topa2{
	width:326px;
	height:24px;
	background:url(../images1/template_tab_background.gif) repeat-x 0 0; 
	font-size:12px;
	margin-left:5px;
	}

 java代码如下:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) throws Exception {
		String absolutePath = "D:\\fff\\template_style.css";
		dispoeStyleContent(absolutePath,"fffffffff", "GBK");
	}

	public static boolean dispoeStyleContent(String styleFilePath,
			String styleImgPath,String charset) throws Exception {
		boolean bool = false;
		String styleContent = "";
		File styleFile = new File(styleFilePath);
		FileOutputStream output = null;
		if (styleFile != null) {
			FileInputStream input = new FileInputStream(styleFile);
			int length = input.available();
			byte[] bytes = new byte[length];
			input.read(bytes);
			styleContent = new String(bytes, charset);
			input.close();			
			//执行过滤处理操作
			styleContent = styleContent.replaceAll("url\\(.+(\\/.+\\..+)\\)", "url\\("+styleImgPath+"$1\\)");


			System.out.println(styleContent);
			output = new FileOutputStream("D:\\fff\\template_style1.css");
			bytes=styleContent.getBytes("GBK");
			output.write(bytes);
			output.flush();
			output.close();
			bool = true;
		}
		return bool;
	}

}

 处理后的结果template_style1.css：

#temoplate_root{
	width:331px;
	height:408px;
	background:url(fffffffff/top.jpg) no-repeat 0 0; 
	font-size:12px;
	border:1px solid #686868;
}
#topa2{
	width:326px;
	height:24px;
	background:url(fffffffff/template_tab_background.gif) repeat-x 0 0; 
	font-size:12px;
	margin-left:5px;
	}
