Object... arguments 的参数形式。

String java.text.MessageFormat.format(String pattern, Object... arguments)

int planet = 7;
String event = "a disturbance in the Force";

String result = MessageFormat.format(
"At {1,time} on {1,date}, there was {2} on planet {0,number,integer}.",
planet, new Date(), event);


直接 写多个对象接可以实现。
