SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder"

自动化框架中，从返回的json字符串中获取值，需要用jsonpath

    com.jayway.jsonpath
    json-path
    2.4.0

运行testng.xml文件报错：

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.

解决方案：

pom中添加如下依赖

        
            org.slf4j
            slf4j-log4j12
            1.7.21
            test
