Properties.load介绍

[英]Loads properties from the specified InputStream, assumed to be ISO-8859-1. See "Character Encoding".
[中]从指定的InputStream加载属性，假定为ISO-8859-1。请参阅“{$0$}”。

代码示例

代码示例来源：origin: square/okhttp

private static String versionString() {
 try {
  Properties prop = new Properties();
  InputStream in = Main.class.getResourceAsStream("/okcurl-version.properties");
  prop.load(in);
  in.close();
  return prop.getProperty("version");
 } catch (IOException e) {
  throw new AssertionError("Could not load okcurl-version.properties.");
 }
}

@Override
public Properties convert(String source) {
  try {
    Properties props = new Properties();
    // Must use the ISO-8859-1 encoding because Properties.load(stream) expects it.
    props.load(new ByteArrayInputStream(source.getBytes(StandardCharsets.ISO_8859_1)));
    return props;
  }
  catch (Exception ex) {
    // Should never happen.
    throw new IllegalArgumentException("Failed to parse [" + source + "] into Properties", ex);
  }
}
