SLF4J: Failed to load class的问题及解决
今天在做接口测试,一运行测试程序,就跳出这样一个大大的错误:
SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”.
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Exception in thread “main” java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
……
原来这是因为sl4j和log4j的不兼容导致的,具体处理方案如下:
1. 首先看看你工程中的sl4j-api的版本(比如我的是1.7.21),
2. 然后在http://mvnrepository.com/搜索slf4j-log4j12,会出现SLF4J LOG4J 12 Binding,
点击进入,会有很多版本的slf4j-log4j12,我们点击1.7.21版本的slf4j-log4j12进入详细信息页面,查看依赖的log4j,这个版本的slf4j-log4j12依赖的是1.2.17版本的log4j。
所以,我们在我们的工程中添加1.7.21版本的slf4j-log4j12和1.2.17版本的log4j,
问题完美解决。
我发现这篇文章比我讲的清楚,请参考:Failed to load class “org.slf4j.impl.StaticLoggerBinder问题故障的解决
This error is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding 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 path should solve the problem.
