如何使用java從excel表提取內容?

在Java程式設計中，如何使用java從excel表提取內容？

專案的目錄結構如下 -

Tika的工具包可從以下網址下載：http://tika.apache.org/download.html ，只下載：tika-app-1.16.jar 和 tika-server-1.16.jar 。

以下是使用java從excel表提取內容的程式 -

import java.io.File;
import java.io.FileInputStream;

import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.microsoft.ooxml.OOXMLParser;
import org.apache.tika.sax.BodyContentHandler;

public class ExtractContentFromExcel {
    public static void main(String args[]) throws Exception {

        // detecting the file type
        BodyContentHandler handler = new BodyContentHandler();

        Metadata metadata = new Metadata();
        FileInputStream inputstream = new FileInputStream(new File("excelExample.xlsx"));

        ParseContext pcontext = new ParseContext();

        // OOXml parser
        OOXMLParser msofficeparser = new OOXMLParser();

        msofficeparser.parse(inputstream, handler, metadata, pcontext);
        System.out.println("Contents of the document:" + handler.toString());
        System.out.println("Metadata of the document:");
        String[] metadataNames = metadata.names();

        for (String name : metadataNames) {
            System.out.println(name + ": " + metadata.get(name));
        }
    }
}

原ODF檔案：excelExample.xlsx 的內容如下 -

執行上面範例程式碼，得到以下結果 -

SLF4J: Found binding in [jar:file:/F:/worksp/javaexamples/libs/tika_libs/tika-app-1.16.jar!/org/slf4j/impl/StaticLoggerBinder.class]
