POI導出Excel的工具類：HSSFWorkbook與SXSSFWorkbook比較

問題：

    當數據量大的時候用POI工具包提供的API創建Excel報錯

原因分析：

1.  可能數據量大導致數據查詢超時或者是請求超時
2. 系統採用的是Apache POI工具進行Excel的創建和導出，會不會是提供的API不能滿足大數據處理的要求？

解決辦法：  

    測試10000-150000條數數據的執行時間，包括數據庫的查詢時間、數據for循環的時間、Excel的創建時間

POI提供兩種導出Excel的工具類：HSSFWorkbook與SXSSFWorkbook

測試結果：

得出結論：

1. 文件格式
    HSSFWorkbook導出的Excel文件以.xls結尾，支持Excel2003
   SXSSFWorkbook導出的Excel文件以.xlsx結尾，支持Excel2007 Excel2010之後的版本 
2. 最大支持條數
   
   HSSFWorkbook最大支持65535條數數據
   SXSSFWorkbook還沒遇到限制
3. 執行效率
   SXSSFWorkbook的創建速度比HSSFWorkbook快
4. 隨着數據量的增加，數據庫的查詢速度越來越慢，並且從發起一次導出請求到結束的整個過程中數據庫的查詢時間佔最大。

程序運行中出現的異常：

1. 當數據量大於65535的時候，HSSFWorkbook報數據超出最大範圍異常

============================================HSSFWorkbook xls格式文件已經不支持，最大支持條數爲65535============================

1. 當數據量大於50000的時候，在導出的過成經常回報java.io.IOException: Broken pipe異常，原因是服務端在

寫入大量數據還沒有完成，客戶端已經關閉連接，該異常對數據的準確性不造成任何危害。
