我遇到错误“类路径包含多个 SLF4J 绑定(bind)。”当启动我的网络应用程序服务器时。我在这里找到的解决方案似乎不起作用。我已从域中排除了 Artifact ，但仍然收到错误。我不明白为什么即使在排除之后也会出现错误。我使用 Glassfish 4.1.1 作为服务器。
Severe: SLF4J: Class path contains multiple SLF4J bindings.
Severe: SLF4J: Found binding in [jar:file:/C:/glassfish4.1.1/glassfish/domains/domain1/eclipseApps/csbasement/WEB-INF/lib/slf4j-log4j12-1.7.12.jar!/org/slf4j/impl/StaticLoggerBinder.class]
Severe: SLF4J: Found binding in [jar:file:/C:/glassfish4.1.1/glassfish/domains/domain1/eclipseApps/csbasement/WEB-INF/lib/slf4j-simple-1.7.12.jar!/org/slf4j/impl/StaticLoggerBinder.class]
Severe: SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
我排除了错误代码中提供的链接中所示的 Artifact :

最佳答案
您正在构建 .jar，通常如果 .jar 不是端点独立应用程序(即您通常从 java 开始 - jar myjar.jar，当您将其作为另一个依赖项添加到 war Web 应用程序中时)，您不应包含 slf4j 实现。因此，只需删除 slf4j-simple 依赖项即可。
关于java - 排除后类路径包含多个 SLF4J 绑定(bind)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33444941/
