java - LogBack 使用 MessageFormat

Question

是否可以在 logback 中使用 MessageFormat？

我看到它使用 slf4j MessageFormatter，因为它更快，如这里所述: Out of curiosity -- why don't logging APIs implement printf()-like logging methods?

SLF4J uses its own message formatting implementation which differs from that of the Java platform. This is justified by the fact that SLF4J's implementation performs about 10 times faster but at the cost of being non-standard and less flexible.

From sf4j Documentation

ideia 是像这样使用 MessageFormat 的完整堆栈功能:

 Object[] arguments = {
     new Integer(7),
     new Date(System.currentTimeMillis()),
     "a disturbance in the Force"
 };

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

 output: At 12:30 PM on Jul 3, 2053, there was a disturbance
           in the Force on planet 7.

有人吗？

我想您已经回答了您自己的问题...基本上这是一个性能问题。如果 slf4j 实现被迫查找和解析参数化……那么……似乎没有人希望在日志系统中拥有的开销。
