return pops.getProperty(key); } 调用文件比如:String s = Property.getProperty("username");
Class GlobalFactory{ /**获取属性property*/ public String getProperties(String property){ Properties pro = new Properties(); InputStream in = GlobalFactory.class .getResourceAsStream("/factory.properties"); try { pro.load(in);
import java.io.*;public class Main2 {
public static void main(String[] args) throws Exception {
Properties p = new Properties();
p.put("name", "value");
p.put("name1", "value1");
p.put("名称", "数值");
//
OutputStream os = new FileOutputStream("main2.properties");
p.store(os, "comments for main2");
InputStream is = new FileInputStream("main2.properties");
p.load(is);
System.out.println(p);
//
is = Main2.class.getResourceAsStream("/main2.properties");
p.load(is);
System.out.println(p);
//
is = Main2.class.getClassLoader().getResourceAsStream("main2.properties");
p.load(is);
System.out.println(p);
}
}
使用store()方法进行保存，使用load()方法加载对应的properties文件，读取和保存的时候汉字都会自动进行转码。main2.properties文件内容如下：#comments for main2
