slf4j-api-1.7.2.jar

Simple Logging Facade for Java (SLF4J) The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time. Note that SLF4J-enabling your library implies the addition of only a single mandatory dependency, namely slf4j-api.jar. If no binding is found on the class path, then SLF4J will default to a no-operation implementation. Java的简单日志外观（SLF4J）作为各种日志框架（例如JavaUTIL日志记录、LogCub、Log4J）的简单外观或抽象，允许终端用户在部署时插入所需的日志框架。
