调试程序出现如下错误:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
下载相应的slf4j的jar包,在slf4j官网下载,
以1.7.21版本为例。
一般只是在程序中引入了slf4j-api-1.7.21.jar文件。
解决方式如下:
解压下载的zip包中,拷贝 slf4j-nop-1.7.21.jar 文件到项目中,再build path, 就解决了。
