Log介绍

[英]Infinispan's log abstraction layer on top of JBoss Logging.

It contains explicit methods for all INFO or above levels so that they can be internationalized. For the commons module, message ids ranging from 0901 to 1000 inclusively have been reserved.

Log log = LogFactory.getLog( getClass() ); The above will get you an instance of Log, which can be used to generate log messages either via JBoss Logging which then can delegate to Log4J (if the libraries are present) or (if not) the built-in JDK logger.

In addition to the 6 log levels available, this framework also supports parameter interpolation, similar to the JDKs String#format(String,Object...)method. What this means is, that the following block: if (log.isTraceEnabled()) { log.trace("This is a message " + message + " and some other value is " + value); }

... could be replaced with ...

if (log.isTraceEnabled()) log.tracef("This is a message %s and some other value is %s", message, value);

This greatly enhances code readability.

If you are passing a Throwable, note that this should be passed in before the vararg parameter list.
[中]Infinispan的日志抽象层位于JBoss日志之上。
它包含用于所有信息或以上级别的显式方法，以便它们可以国际化。对于commons模块，已保留范围为0901到1000（含）的消息ID。
上面的Log log = LogFactory.getLog( getClass() );将为您提供一个Log实例，可以通过JBoss日志生成日志消息，然后可以将日志消息委托给Log4J（如果有库）或（如果没有库）内置JDK日志。
除了可用的6个日志级别之外，该框架还支持参数插值，类似于JDKs字符串#格式（字符串、对象…）方法这意味着，下面的块：if (log.isTraceEnabled()) { log.trace("This is a message " + message + " and some other value is " + value); }
... 可以替换为。。。
if (log.isTraceEnabled()) log.tracef("This is a message %s and some other value is %s", message, value);
这大大提高了代码的可读性。
如果您要传递一个Throwable，请注意这应该在vararg参数列表之前传递。
