Java 类路径包含排除后的多个SLF4J绑定

启动web应用服务器时出现错误“类路径包含多个SLF4J绑定”。我在这里找到的解决方案似乎不起作用。我已经从域中排除了工件，但仍然得到了错误。我不明白为什么即使在排除后我也会有错误。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.

我排除了在错误代码中提供的链接中看到的工件：

您正在构建

.jar

，通常，如果

.jar

不是一个端点独立的应用程序（即，您通常从

java-jar myjar.jar

开始，而您正在将它作为另一个依赖项添加到

war

web应用程序中），则不应包含slf4j实现。因此，只需删除

slf4j简单的

依赖项。

什么是

mvn依赖项：树

打印输出？您可能有一些可传递的依赖项，需要特别排除。@hotzst感谢您的帮助，我添加了mvn树。

mvn:tree

显示为

.jar

依赖项，而您正在抱怨web应用程序。jar没有

slf4j-log4j12

它是以其他方式提供的，您没有展示如何使用它。你提到的排除没有任何意义，因为没有什么可以排除的-提到的

.jar

没有

log4j12

。这里它说，这只是一个警告：@Betlista这是一个很好的警告，应该得到修复。我添加了依赖项，因为如果我没有，我会出现另一个错误

SLF4J:无法加载类“org.slf4j.impl.StaticLoggerBinder“

@Ced所以，在你添加

slf4j simple

之前，你没有

C:/glassfish4.1.1/glassfish/domains/domain1/eclipseApps/csbase/WEB-INF/lib/slf4j-log4j12-1.7.12.jar

，在你有了这两个之后，我想，至少错误是这么说的。实际上，我在stackoverflow上发现了一个线程，

加载类失败的答案是添加——简单依赖项。
