maven项目编译不报错,运行时报错如下:
SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [bundle://11.0:23/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [bundle://11.0:93/org/slf4j/impl/StaticLoggerBinder.class]
此错误表明:在类路径中有多个SLF4J实现。SLF4J仅允许有一个绑定类,我们需要消除不需要的绑定类,
通过maven命令找到不需要的SLF4J的实现,更新pom.xml
