SLF4J SLF4J:类路径包含多个Maven绑定

Question

在运行我的java代码时，我得到了以下运行时异常。有没有人能帮我解决绑定冲突。

    SLF4J: Class path contains multiple SLF4J bindings.

Answer 1

您似乎有几个SLF4J实现；您应该排除所有不必要的实现

Answer 2

这个错误意味着您的类路径中有多个SLF4J实现。查看这些错误具体说明了什么。即：SLf4J: Found binding in..... (这将打印它找到StaticLoggerBinder.class实例的所有jar文件)。从类路径中删除所有此类jar，但需要其StaticLoggerBinder.class实现的jar除外。

Answer 3

您可以转到POM.xml，打开依赖关系层次结构，然后通过右键单击"exclude maven entries.Except“找到slf4j maven one exclude one
