java怎么实现记住密码功能

Answer 1

是要在客户端记住密码然后能自动登录的那种是么？我虽然没用过，但我想应该是保存在cookie中的吧，然后对cookie设个保存时间，就能做到一段时间保存密码了吧！！新手回答，如果对了，求采纳！

Answer 2

//根据key读取value
public static String readValue(String filePath,String key) {
Properties props = new Properties();
Property property=new Property();
try{
key=new String(key.getBytes("GB2312"),"ISO-8859-1");
key= Entropy.encrypt(key, "123");
}catch (UnsupportedEncodingException ex){}
try {
InputStream in = new BufferedInputStream (new FileInputStream(filePath));
props.load(in);
String value = new String(props.getProperty (key).getBytes("ISO-8859-1"),"GB2312");
value= Entropy.decrypt(value, "123");
return value;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
