java关于ini文件的生成与修改

java的一些工具包

http://www.oschina.net/project/tag/143/utils

在一些项目中经常用到保存一个配置文件，但是配置文件一般都用ini格式进行保存

那么对于该文件的类型怎么创建又怎么进行修改的呢？

下面是一种很方面的方法：

package cn.com.shine.ini;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;

public class Tools {

	static Map> iniFile = new HashMap>();


	public  void write(String name) throws IOException {
		StringBuilder sb = new StringBuilder("");
		for (String section : iniFile.keySet()) {
			sb.append("[").append(section).append("]").append("\n");
			Map map = iniFile.get(section);
			Set keySet = map.keySet();
			for (String key : keySet) {
				sb.append(key).append("=").append(map.get(key)).append("\n");
			}
		}
		File file = new File(name);
		if (!file.exists()) {
			file.createNewFile();
		}
		try {
			OutputStream os = new FileOutputStream(file);
			os.write(sb.toString().getBytes());
			os.flush();
			os.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	public  void setValue(String section, String key, Object value) {
		Map sectionMap = iniFile.get(section);
		if (sectionMap == null) {
			sectionMap = new HashMap();
			iniFile.put(section, sectionMap);
		}
		sectionMap.put(key, value);
	}

	public  Object getValue(String section, String key) {
		Object obj = null;
		Map item = iniFile.get(section);
		if (item != null) {
			obj = item.get(key);
		}
		return obj;

	}
}

方法调用：

package cn.com.shine.ini;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

public class IniSrc {
		/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Tools tools=new Tools();
		/*tools.setValue("ip", "ip_address", "183.126.125.152");
		tools.setValue("ip1", "ip_address1", "184.126.125.152");
		tools.setValue("ip2", "ip_address2", "185.126.125.152");
		tools.setValue("ip3", "ip_address3", "186.126.125.152");
		tools.setValue("ip4", "ip_address4", "187.126.125.152");*/
		tools.setValue("ip", "ip_address", "183");
		try {
			tools.write("E:\\NET.ini");
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		
	}

}

=======================================

另外一种是调用第三方jar包

http://javaini.sourceforge.net/

此类库可以在此下载：

不过不支持中文，若要需要支持中文，可以对源代码进行修改，如把编码格式修改就可以：

修改应该在这个地方：
