POI SAX 使用事件驅動解析Excel(03/07)

阿新 • • 發佈：2019-02-16

本文主要是用於POI解析大檔案Excel容易出現記憶體溢位的現象而提出解決方案，故此解決了大資料量的Excel檔案解析的難度，在此拿出來貢獻給大家，謝謝！

裡面用到的相關類請檢視: http://www.cnblogs.com/wshsdlau/p/5643862.html

1. Office2007與Office Open XML

在Office 2007之前，Office一直都是以二進位制位的方式儲存，但這種格式不易被其它軟體拿來使用，在各界的壓力下，MicroSoft於2005年釋出了基於XML的ooxml開放文件標準。ooxml的xml schema強調減少load time，增快parsing speed，將child elements分開儲存，而不是multiple attributes一起存，這有點類似於HTML的結構。ooxml 使用XML和ZIP技術結合進行檔案儲存，因為XML是一個基於文字的格式，而且ZIP容器支援內容的壓縮，所以其一大優勢就是可以大大減小檔案的尺寸。其它特點這裡不再敘述。

2. SAX方式解析XML

SAX全稱Simple API for XML，它是一個介面，也是一個軟體包。它是一種XML解析的替代方法，不同於DOM解析XML文件時把所有內容一次性載入到記憶體中的方式，它逐行掃描文件，一邊掃描，一邊解析。所以那些只需要單遍讀取內容的應用程式就可以從SAX解析中受益，這對大型文件的解析是個巨大優勢。另外，SAX “推" 模型可用於廣播環境，能夠同時註冊多個ContentHandler，並行接收事件，而不是在一個管道中一個接一個地進行處理。一些支援 SAX 的語法分析器包括 Xerces，Apache parser（以前的 IBM 語法分析器）、MSXML（Microsoft 語法分析器）和 XDK（Oracle 語法分析器）。這些語法分析器是最靈活的，因為它們還支援 DOM。

3. POI以SAX解析excel2007檔案

所需jar包：poi-3.10-FINAL-20140208.jar，poi-ooxml-3.10-FINAL-20140208.jar， poi-ooxml-schemas-3.10-FINAL-20140208.jar

xercesImpl.jar xml-apis-2.0.2.jar xmlbeans-2.6.0.jar sax2.jar
