Log4j是否被抛弃而支持Slf4j？ [英] Is Log4j being abandoned in favor of Slf4j?

问题描述

似乎log4j有一些类加载问题（等等）在我看来，趋势是从log4j移出slf4j。 （Hibernate停止使用第一个支持后者）

It seems that log4j has some class loading issues (among others) and it seems to me the trend is to move out of log4j toward slf4j. (Hibernate stopped using the first in favor of the latter)

1. 这是真的吗？


2. 什么是stlf4j解决的log4j中的主要问题吗？


3. slf4j是最后一个字还是更好的下一个下一个log4j行业标准？

You appear to have stumbled upon the major problem with log4j (and the Apache Commons Logging library), namely that they have a ridiculously hard time discovering and interacting with the right classloaders as they're being used. There's a very dense explanation, complete with examples, here; the take-home message is that one of the primary driving forces for the new logging framework SLF4J was to eliminate these issues entirely. You might want to swap it in and see if your life is made any easier.

推荐答案

Slf4j确实只是一个日志记录。但是，Log4j旨在由来自同一作者的 Logback 继承。

Slf4j is indeed just a logging facade. However, Log4j is intended to be succeeded by Logback, from the very same authors.

更新：如果您想了解Slf4j的另一个好处，那就是不再需要以下（丑陋）构造来避免<$ strong c $ c> toString（）不必要地被调用：

Update: if you'd like to know about another benefit of Slf4j, it's the fact that following (ugly) constructs aren't needed anymore to avoid the toString() unnecessarily been called:

if (logger.isDebugEnabled()) {
    logger.debug("Message: " + bigObject + ", " + anotherBigObject);
}

您可以改为使用参数化消息：

You can instead make use of parameterized messages:

logger.debug("Message: {}, {}", bigObject, anotherBigObject);

另见（不）记录的最快方法是什么？
