其实很简单的


import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;

public class CfgWriter {
	private PrintWriter out;
	private static final String DEFINE = "define";

	public CfgWriter(File file) throws FileNotFoundException {
		super();
		this.out = new PrintWriter(file);
	}

	public void writeComment(String comment) {
		out.print('#');
		out.println(comment);
	}

	public void startDefine(String name) {
		out.print(DEFINE);
		out.print(' ');
		out.print(name);
		out.println('{');
	}

	public void writeProperty(String key, String value) {
		out.print(' ');
		out.print(key);
		out.print('\t');
		out.println(value);
	}

	public void endDefine() {
		out.println('}');
	}

	public void close() {
		out.close();
	}

	public static void main(String[] args) throws Exception {
		CfgWriter w = new CfgWriter(new File("d:/config.cfg"));
		w.writeComment("config.cfg");
		w.startDefine("Server");
		w.writeProperty("Id", "0001");
		w.writeProperty("Name", "xxxx");
		w.writeProperty("Amount", "100");
		w.endDefine();
		w.close();
	}
}
