Apache HTTPClient没有这样的方法ContentType.create

Question

堆栈跟踪我得到的是这个.

[04:18:36 WARN]: java.lang.NoSuchMethodError: org.apache.http.entity.ContentType.create(Ljava/lang/String;[Lorg/apache/http/NameValuePair;)Lorg/apache/http/entity/ContentType;

触发的线是这个.

response = client.execute(httpPost);

在我看来你要么错过了一个库,要么你的类路径上有一个错误的库版本.我怀疑httpcore和/或httpmime库.
