今天学习Web Service时遇到如下问题

2017-10-25 13:52:46 org.apache.cxf.wsdl.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://ws.com/}HelloWSImplService from class com.ws.HelloWS
2017-10-25 13:52:47 org.apache.cxf.endpoint.ServerImpl initDestination

Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

这是由于Slf4j jar包与其他jar冲突导致。那问题如何解决呢？

1、首先我们需要找出冲突的jar包都有哪些.

　　ctrl+shift+T，连jar包中的类也可以搜索出来。这个可以很好的查找jar包冲突的问题。看某个class在哪些jar包中存在.

 

2、删除里面的slf4j就没有出现这个情况了。
