2018-07-20 来源:open-open
POI是apache的开源项目,其地址在http://poi.apache.org/
下面是起官方网站的标题,POI是微软文档的javaAPI
Apache POI - the Java API for Microsoft Documents。
下面是一个POI读写word表格的例子:
import java.io.FileInputStream; import java.io.FileOutputStream; import java.util.HashMap; import java.util.Map; import java.util.Set; import org.apache.poi.hwpf.HWPFDocument; import org.apache.poi.hwpf.usermodel.Paragraph; import org.apache.poi.hwpf.usermodel.Range; import org.apache.poi.hwpf.usermodel.Table; import org.apache.poi.hwpf.usermodel.TableCell; import org.apache.poi.hwpf.usermodel.TableIterator; import org.apache.poi.hwpf.usermodel.TableRow; public class POIWordUtil { public static void main(String[] args) throws Exception { Map<String, Text> replaces = new HashMap<String, Text>(); replaces.put("${username}", Text.str("rongzhi_li")); replaces.put("${password}", Text.str("1123456")); replaces.put("${author}", Text.str("lee")); poiWordTableReplace("t1.doc", "t2.doc", replaces); } public static void poiWordTableReplace(String sourceFile, String newFile, Map<String, Text> replaces) throws Exception { FileInputStream in = new FileInputStream(sourceFile); HWPFDocument hwpf = new HWPFDocument(in); Range range = hwpf.getRange();// 得到文档的读取范围 TableIterator it = new TableIterator(range); // 迭代文档中的表格 while (it.hasNext()) { Table tb = (Table) it.next(); // 迭代行,默认从0开始 for (int i = 0; i < tb.numRows(); i++) { TableRow tr = tb.getRow(i); // 迭代列,默认从0开始 for (int j = 0; j < tr.numCells(); j++) { TableCell td = tr.getCell(j);// 取得单元格 // 取得单元格的内容 for (int k = 0; k < td.numParagraphs(); k++) { Paragraph para = td.getParagraph(k); String s = para.text(); final String old = s; for (String key : replaces.keySet()) { if (s.contains(key)) { s = s.replace(key, replaces.get(key).getText()); } } if (!old.equals(s)) {// 有变化 para.replaceText(old, s); s = para.text(); System.out.println("old:" + old + "->" + "s:" + s); } } // end for } // end for } // end for } // end while FileOutputStream out = new FileOutputStream(newFile); hwpf.write(out); out.flush(); out.close(); } } public abstract class Text { public abstract String getText(); public static Text str(final String string) { return new Text() { @Override public String getText() { return string; } }; } }
