由于公司不允许使用System.out.println(),学习了logback,特意记下遇到问题,供新手参考: 建立在控制台能输出内容的情况下:如果不能输出,比如No SLF4J providers were found 很可能你的包没有导全。 如果是maven项目,我的步骤是这样: 新建maven项目,这里需要贴出来是因为pom.xml会根据你所填自动生成一些代码: 可看...

看起来很完美，项目也能正常启动。但当模块A需要打印日志时，我们却还是得到了一个错误log4j:WARN No appenders could be found for logger (xxx.xxx.xxx)。这是因为log4j-over-slf4j并没有真的被引入我们的项目中（很少有哪个二方包会引这种东西，会被骂的）。解决方案也很简单，将log4j-over-slf4j通过<...
Slf4j 2.0.x有不小的改动[3],不再主动查找org.slf4j.impl.StaticLoggerBinder,而是改用JDK ServiceLoader[4](也就是SPI,Service Provider Interface) 的方式来加载实现。这是JDK 8中的特性,所以Slf4j对JDK的依赖显而易见: 其中,Slf4j在发布了几个1.8 alpha/beta版后,直接跳到了2.0,所以1.8不在我们的讨论范...
I'm seeing this issue in both j8 and j11. I have a lambda to which I need to move to logback for json logging. But before I do that I wanted to get logback in place of the default log4j logging . I first got theSLF4J: No SLF4J providers were found.with the default configuration...

This version of logback targets SLF4J 1.7.x or earlier and is incompatible with version 2.0.7, as per thedocs here. It also results in the following error when invoking Serenity BDD CLI: SLF4J: No SLF4J providers were found. SLF4J: Defaulting to no-operation (NOP) logger implementation ...
通过org.slf4j:jcl-over-slf4j将JCL桥接到Slf4j 上; 通过org.slf4j:log4j-over-slf4j将Log4j桥接到Slf4j 上; 通过org.slf4j:jul-to-slf4j将JUL桥接到Slf4j上; 注意,所有org.slf4j的包版本要完全一致,所以如果引入这些桥接包,要保证它们的版本与前边选择的slf4j-api版本对应。为此Slf4j从2.0.8开始提供了bo...
然而，尽管项目能够正常启动，当模块A尝试打印日志时，却出现了错误：log4j:WARN No appenders could be found for logger (xxx.xxx.xxx)。这表明log4j-over-slf4j并未真正被引入项目（通常不会有这样的二方包被引入，因此可能被忽略了）。为了解决这个问题，我们需要在父POM或实际依赖的子POM中显式引入log4j-over...
No SLF4J providers were found. This warning, i.e. not an error, message is reported when no SLF4J providers could be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class ...
