=====百度==

org.apache.http.client.HttpClient使用中，報瞭如下的異常：
Invalid use of SingleClientConnManager: connection still allocated.
Make sure to release the connection before allocating another one.
此問題出現緣由是併發調用同一個httpclient去請求數據。在上一個post|get請求還沒有結束時，又啓新的線程再次使用該httpclient請求數據。
目前個人解決方法是用synchronized關鍵字同步httpclient請求數據的操做。但這個解決方案不能解決併發使用同一個httpClient請求數據的需求，本人對httpclient不精通，有更好解決方法的大神，請不吝賜教！
