英文:
Is there a string formatter that will use the same syntax as SLF4J?
问题
我（显然）熟悉String.format()和MessageText.format()两者——我也理解在Slf4j日志记录中使用的字符串格式化语法；令人沮丧的是它们都不同且不兼容。
我正在寻找的是一个类似于MessageText.format()的函数，它能像slf4j日志记录器的格式化器一样工作，这样我就可以在日志消息和（例如）异常消息中都使用相同的字符串常量：
public static String THIS_HAPPENED =
"Unfortunately, foo was {}, but bar ({}) was not";
// ...
if (someDisaster(foo, bar)) {
log.error(THIS_HAPPENED, foo, bar);
throw new IllegalStateException(MessageText.betterFormat(THIS_HAPPENED,
foo, bar));
}
不幸的是，MessageText需要位置指示符（{0}），而Slf4j对此极为反感。
在这方面是否有一些解决方案？
（显然，显然！）我可以自己编写这个方法，但如果已经有比我更优秀的程序员已经完成了，我愿意使用那个方法。
非常感谢！
英文:
I am (obviously) familiar with both String.format() and MessageText.format() - I also understand the string formatting syntax used in Slf4j logging; it is frustrating that they are all different and incompatible.
What I am looking for is a MessageText.format() -like function, that works exactly as the slf4j loggers' formatters, so I can use the same String constants both in log messages and in (for example) exception messages:
public static String THIS_HAPPENED =
"Unfortunately, foo was {}, but bar ({}) was not";
// ...
if (someDisaster(foo, bar)) {
log.error(THIS_HAPPENED, foo, bar);
throw new IllegalStateException(MessageText.betterFormat(THIS_HAPPENED,
foo, bar));
}
Unfortunately, MessageText needs the position specifier ({0}) and Slf4j positively hates it.
Is there something out there that does this?
(Obviously, obviously!, I can write the method myself, but if it's already been done by coders better than I, I would happily use that instead).
Many thanks in advance.

尝试一下：
import org.slf4j.helpers.MessageFormatter;
在这里你有：
MessageFormatter.format(messagePattern, arg).getMessage();
英文:
Try to:
import org.slf4j.helpers.MessageFormatter;
there you have:
MessageFormatter.format(messagePattern, arg).getMessage();
