org.apache.tomcat.jni.LibraryNotFoundError: Can‘t load library: E:\workspace\zjqywx\bin\tcnative-1.d

  错误起因是我要修改httpclient的日志等级，用的这个httpclient工具 

       
            org.apache.httpcomponents
            httpclient
            4.5.5
        

 

当时在logback-spring.xml添加了下面三个配置语句

结果导致了下面的错误

其中导致了上面的错误，去掉即可
