java.lang.NoSuchFieldError: INSTANCE at com.amazonaws.http.conn.SdkConnectionKeepAliveStrategy.ge

在测试aws的s3本地测试的时候会遇到这样的错误：

java.lang.NoSuchFieldError: INSTANCE   at com.amazonaws.http.conn.SdkConnectionKeepAliveStrategy.getKeepAliveDuration(SdkConnectionKeepAliveStrategy.java:48)

此错误主要是httpclient包与aws内置的jar有冲突导致的，在pom.xml中添加对应的jar即可
