尝试将AWS SDK实现到Java Web应用程序时,我遇到了错误.我正在尝试编写一个简单的方法将图像保存到S3 Bucket,当我触发该方法时会发生错误.

堆栈跟踪

SEVERE: Servlet.service() for servlet dispatcher threw exception
java.lang.NoSuchMethodError: org.apache.http.params.HttpConnectionParams.setSoKeepalive(Lorg/apache/http/params/HttpParams;Z)V

基于我从Google看到的内容,我感觉这个问题与我的Build Path配置错误有关.我已经包含了所有的AWS罐子以及所有第三方罐子,并且我已经完成并删除了旧版本的库.
