在JAVA下實現數據庫對word文件的讀取與字段的提取
在JAVA下實現數據庫對word文件的讀取與字段的提取
實現excel中的數據導入數據庫，在java或是C#下是不難實現的，即便想實如今txt中的數據導入也不是什麼難事，可是，最近接了個任務，學校要建一個英文版的教學平臺，而後各個學院的課程資料與簡介什麼的都是英文的，學校有20個學院，每一個學院多的有兩百來個科目，少的也有百八十種，可他恰恰就是個word，並且，作的格式很不規範。這可愁着我了，我首先想到的是POI，因而google了一下，原來真的很容易實現，這個後面的代碼能夠發上去，能夠實現03版，和07版的。差異主要是jar包的問題。03的要3個jar包，07的須要7個jar包。html

public class Test {
public static void main(String[] args) {
try {
////word 2003： 圖片不會被讀取
InputStream is = new FileInputStream(new File("files\\2003.doc"));
WordExtractor ex = new WordExtractor(is);//is是WORD文件的InputStream
String text2003 = ex.getText();
System.out.println(text2003);
//對字符串進行分解
//word 2007 圖片不會被讀取， 表格中的數據會被放在字符串的最後
OPCPackage opcPackage = POIXMLDocument.openPackage("files\\2007.docx");
POIXMLTextExtractor extractor = new XWPFWordExtractor(opcPackage);
String text2007 = extractor.getText();
System.out.println(text2007);
} catch (Exception e) {
e.printStackTrace();
}
}
}
而後，重要的問題是，如何從word的字段中抓去文件纔是關鍵，由於他們提供的word文件並非excel，並不能直接導入，我仍是果斷上一個word文件吧，這樣好理解：java

反正此次任務很麻煩，看起來，各個科目弄的很專業，很標準，可是，不一樣老師作的，一些標點符號仍是整的很亂，有的是英文的標點，有的是中文的，有的是半角的，有的是全角的，形成了數據庫裏面全是亂碼，到如今沒發改了，全辦公室集體上陣，一人分幾個學院，挨條記錄看，挨條記錄改，糾結ing。。。。。。
