这个错误有什么不对

Question

Spring框架抛出

Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V
    at org.apache.commons.logging.impl.SLF4JLocationAwareLog.info(SLF4JLocationAwareLog.java:159)
    at org.springframework.context.support.AbstractApplicationContext.prepareRefresh(AbstractApplicationContext.java:454)
    at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:392)
at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:139)
at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:93)

什么原因？

Answer 1

原因是添加了错误的库版本(版本冲突).

检查slf4j's javadoc 的版本并试着搞清楚,这个方法存在哪个版本？
