    有一word文档表格

    形如:

    姓名 ${name} 

    电话 ${tel}

    从数据库读取记录替换上述变量

    import java.io.FileOutputStream;
    import java.util.HashMap;
    import java.util.Iterator;
    import java.util.List;
    import java.util.Map;
    import java.util.Map.Entry;
    import org.apache.poi.POIXMLDocument;
    import org.apache.poi.xwpf.usermodel.XWPFDocument;
    import org.apache.poi.xwpf.usermodel.XWPFTable;
    import org.apache.poi.xwpf.usermodel.XWPFTableCell;
    import org.apache.poi.xwpf.usermodel.XWPFTableRow;
    
    public class DOCWriter {
        public static void searchAndReplace(String srcPath, String destPath,
                Map<String, String> map) {
            try {
                XWPFDocument document = new XWPFDocument(POIXMLDocument
                        .openPackage(srcPath));
                Iterator it = document.getTablesIterator();
                while (it.hasNext()) {
                    XWPFTable table = (XWPFTable) it.next();
                    int rcount = table.getNumberOfRows();
                    for (int i = 0; i < rcount; i++) {
                        XWPFTableRow row = table.getRow(i);
                        List<XWPFTableCell> cells = row.getTableCells();
                        for (XWPFTableCell cell : cells) {
                            for (Entry<String, String> e : map.entrySet()) {
                                if (cell.getText().equals(e.getKey())) {
                                    cell.removeParagraph(0);
                                    cell.setText(e.getValue());
                                }
                            }
                        }
                    }
                }
                FileOutputStream outStream = null;
                outStream = new FileOutputStream(destPath);
                document.write(outStream);
                outStream.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
        public static void main(String[] args) throws Exception {
            HashMap map = new HashMap();
            map.put("${name}", "王五");
            map.put("${tel}", "8886666");
            String srcPath = "c:\1.docx";
            String destPath = "c:\2.doc";
            searchAndReplace(srcPath, destPath, map);
        }
    }

    以上方法,直接考入导入包后直接可运行
