java - SLF4J : Failed to load class "org.slf4j.impl.StaticLoggerBinder". Java应用程序错误

Question

我正在使用 Java 编写服务器端套接字应用程序，但我不知道什么会导致此错误

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.

如何解决这个问题？

您收到此消息是因为 slf4j 在您的类路径中找不到绑定(bind)。 slf4j 就像其他日志框架的包装器。它需要您打算使用的日志框架的绑定(bind)库来实际记录消息。例如，要使用 log4j，请添加库 slf4j-log4j12.jar 和 log4j.jar。更多详细信息可以在 SLF4J 手册中找到:http://www.slf4j.org/manual.html .

To switch logging frameworks, just replace slf4j bindings on yourclass path. For example, to switch from java.util.logging to log4j,just replace slf4j-jdk14-1.7.10.jar with slf4j-log4j12-1.7.10.jar.

SLF4J does not rely on any special class loader machinery. In fact,each SLF4J binding is hardwired at compile time to use one and onlyone specific logging framework. For example, theslf4j-log4j12-1.7.10.jar binding is bound at compile time to uselog4j. In your code, in addition to slf4j-api-1.7.10.jar, you simplydrop one and only one binding of your choice onto the appropriateclass path location. Do not place more than one binding on your classpath.
