poi-tl实现自定义RenderPolicy实现对表格进行列表
主程序如下：
import java.util.List;
import java.util.Map;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
import com.deepoove.poi.NiceXWPFDocument;
import com.deepoove.poi.XWPFTemplate;
import com.deepoove.poi.data.TableRenderData;
import com.deepoove.poi.policy.RenderPolicy;
import com.deepoove.poi.template.ElementTemplate;
import com.deepoove.poi.template.run.RunTemplate;
import net.ulsc.app.gzkg.C;
public class MyTableRenderPolicy implements RenderPolicy {
@Override
public void render(ElementTemplate eleTemplate, Object data, XWPFTemplate template) {
// TODO Auto-generated method stub
NiceXWPFDocument doc = template.getXWPFDocument();
RunTemplate runTemplate = (RunTemplate) eleTemplate;
XWPFRun run = runTemplate.getRun();
if (null == data) {
// clear table
runTemplate.getRun().setText("", 0);
runTemplate.getRun().removeTab();
XWPFHelper.clearTable(eleTemplate.getTagName(), doc.getTables(), run);
return;
}
TableRenderData tableData = (TableRenderData) data;
List
工具类如下：
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl;
public class XWPFHelper {
public static Map getTable(String pattern, List tables) {
Map m = new HashMap<>();
for (XWPFTable t : tables) {
if (t.getText().contains(pattern)) {
m.put("table", t);
// m.put("startRow", i);
// m.put("startCell", j);
return m;
}
}
return m;
}
public static void clearTable(String pattern, List tables, XWPFRun run) {
// 清除自定义表格填写内容
List rows = null;
List cells = null;
for (XWPFTable t : tables) {
if (t.getText().contains(pattern)) {
rows = t.getRows();
//删除模板表格中新增加的行
for (int i = 2; i < rows.size(); i++) {
t.removeRow(i);
}
cells = rows.get(1).getTableCells();
for (XWPFTableCell cell : cells) {
XWPFParagraph par = cell.getParagraphs().get(0);
for (XWPFRun r : par.getRuns()) {
r.setText("", 0);
}
}
}
}
}
// 复制单元格
public static void copyTableCell(XWPFTableCell target, XWPFTableCell source) {
// 列属性
target.getCTTc().setTcPr(source.getCTTc().getTcPr());
// 删除目标 targetCell 所有单元格
for (int pos = 0; pos < target.getParagraphs().size(); pos++) {
target.removeParagraph(pos);
}
// 添加段落
for (XWPFParagraph sp : source.getParagraphs()) {
XWPFParagraph targetP = target.addParagraph();
copyParagraph(targetP, sp);
}
}
// public static void CopyRun(XWPFRun target, XWPFRun source) {
// target.getCTR().setRPr(source.getCTR().getRPr());
// // 设置文本
// target.setText(source.text());
// }
public static void copyParagraph(XWPFParagraph target, XWPFParagraph source) {
// 设置段落样式
target.getCTP().setPPr(source.getCTP().getPPr());
// 添加Run标签
for (int pos = 0; pos < target.getRuns().size(); pos++) {
target.removeRun(pos);
}
// for (XWPFRun s : source.getRuns()) {
// XWPFRun targetrun = target.createRun();
// CopyRun(targetrun, s);
// }
}
public static void copytTableRow(XWPFTableRow target, XWPFTableRow source) {
// 复制样式
target.getCtRow().setTrPr(source.getCtRow().getTrPr());
// 复制单元格
for (int i = 0; i < target.getTableCells().size(); i++) {
copyTableCell(target.getCell(i), source.getCell(i));
}
}
public static XWPFRun getRun(XWPFTableCell cell, XWPFRun source) {
XWPFParagraph par = cell.getParagraphs().get(0);
// XWPFRun r = par.getRuns().size() > 0 ? par.getRuns().get(0) :
// par.createRun();
XWPFRun r = par.createRun();
r.getCTR().setRPr(source.getCTR().getRPr());// 复制 run
r.setFontFamily(source.getFontFamily());
r.setFontSize(source.getFontSize());
par.removeRun(source.getTextPosition());
return r;
}
public static XWPFTable getTableByTBL(List tables, CTTbl tbl) {
for (int i = 0; i < tables.size(); i++) {
if (tables.get(i).getCTTbl() == tbl)
return tables.get(i);
}
return null;
}
}
//初始化模板
//调用
XWPFTemplate tt = XWPFTemplate.compile(FileTools.getInstance().getArchiveFile(1),
FileTools.getInstance().getMyarchiveConfigure());
//FileTools工具类中方法getMyarchiveConfigure
public Configure getMyarchiveConfigure() {
if(null==this.myarchiveConfigure) {
this.myarchiveConfigure=Configure.createDefault();
this.myarchiveConfigure=this.myarchiveConfigure.plugin('&', new
MyTableRenderPolicy()).plugin('$', new MyPictureRenderPolicy());
}
return myarchiveConfigure;
}
模板如下图所示：
实现效果如下图所示：
循环时数据覆盖问题解决：
XWPFTemplate tt = XWPFTemplate.compile(FileTools.getInstance().getArchiveFile(1),
FileTools.getInstance().getMyarchiveConfigure());
Map clearData = new HashMap<>();
//将模板中的标签key的值都设置为null
for (ElementTemplate et : tt.getElementTemplates()) {
clearData.put(et.getTagName(), null);
}
//循环中将清除模板中的数据
while (mit.hasNext()) {
// 先render 一个空数据，包括所有的标签
tt.render(clearData);//清空数据
