POI Word 模板 文字 图片 替换

实验环境：POI3.7+Word2007

Word模板：



替换后效果：



代码：

1、入口文件

public class Test {

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

Map<String, Object> param = new HashMap<String, Object>();
param.put("${name}", "huangqiqing");
param.put("${zhuanye}", "信息管理与信息系统");
param.put("${sex}", "男");
param.put("${school_name}", "山东财经大学");
param.put("${date}", new Date().toString());

Map<String,Object> header = new HashMap<String, Object>();
header.put("width", 100);
header.put("height", 150);
header.put("type", "jpg");
header.put("content", WordUtil.inputStream2ByteArray(new FileInputStream("c:\\new.jpg"), true));
param.put("${header}",header);

Map<String,Object> twocode = new HashMap<String, Object>();
twocode.put("width", 100);
twocode.put("height", 100);
twocode.put("type", "png");
twocode.put("content", ZxingEncoderHandler.getTwoCodeByteArray("测试二维码,huangqiqing", 100,100));
param.put("${twocode}",twocode);

CustomXWPFDocument doc = WordUtil.generateWord(param, "c:\\1.docx");
FileOutputStream fopts = new FileOutputStream("c:/2.docx");
doc.write(fopts);
fopts.close();
}
}

2、封装的工具类WordUtil.java

package test1;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

import org.apache.poi.openxml4j.opc.OPCPackage;
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;

/**
* 适用于word 2007
* poi 版本 3.7
*/
public class WordUtil {

/**
* 根据指定的参数值、模板，生成 word 文档
* @param param 需要替换的变量
* @param template 模板
*/
public static CustomXWPFDocument generateWord(Map<String, Object> param, String template) {
CustomXWPFDocument doc = null;
try {
OPCPackage pack = POIXMLDocument.openPackage(template);
doc = new CustomXWPFDocument(pack);
if (param != null && param.size() > 0) {

//处理段落
List<XWPFParagraph> paragraphList = doc.getParagraphs();
processParagraphs(paragraphList, param, doc);

//处理表格
Iterator<XWPFTable> it = doc.getTablesIterator();
while (it.hasNext()) {
XWPFTable table = it.next();
List<XWPFTableRow> rows = table.getRows();
for (XWPFTableRow row : rows) {
List<XWPFTableCell> cells = row.getTableCells();
for (XWPFTableCell cell : cells) {
List<XWPFParagraph> paragraphListTable =  cell.getParagraphs();
processParagraphs(paragraphListTable, param, doc);
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return doc;
}
/**
* 处理段落
* @param paragraphList
*/
public static void processParagraphs(List<XWPFParagraph> paragraphList,Map<String, Object> param,CustomXWPFDocument doc){
if(paragraphList != null && paragraphList.size() > 0){
for(XWPFParagraph paragraph:paragraphList){
List<XWPFRun> runs = paragraph.getRuns();
for (XWPFRun run : runs) {
String text = run.getText(0);
if(text != null){
boolean isSetText = false;
for (Entry<String, Object> entry : param.entrySet()) {
String key = entry.getKey();
if(text.indexOf(key) != -1){
isSetText = true;
Object value = entry.getValue();
if (value instanceof String) {//文本替换
text = text.replace(key, value.toString());
} else if (value instanceof Map) {//图片替换
text = text.replace(key, "");
Map pic = (Map)value;
int width = Integer.parseInt(pic.get("width").toString());
int height = Integer.parseInt(pic.get("height").toString());
int picType = getPictureType(pic.get("type").toString());
byte[] byteArray = (byte[]) pic.get("content");
ByteArrayInputStream byteInputStream = new ByteArrayInputStream(byteArray);
try {
int ind = doc.addPicture(byteInputStream,picType);
doc.createPicture(ind, width , height,paragraph);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
if(isSetText){
run.setText(text,0);
}
}
}
}
}
}
/**
* 根据图片类型，取得对应的图片类型代码
* @param picType
* @return int
*/
private static int getPictureType(String picType){
int res = CustomXWPFDocument.PICTURE_TYPE_PICT;
if(picType != null){
if(picType.equalsIgnoreCase("png")){

}
return res;
}
/**
* 将输入流中的数据写入字节数组
* @param in
* @return
*/
public static byte[] inputStream2ByteArray(InputStream in,boolean isClose){
byte[] byteArray = null;
try {
int total = in.available();
byteArray = new byte[total];
in.read(byteArray);
} catch (IOException e) {
e.printStackTrace();
}finally{
if(isClose){
try {
in.close();
} catch (Exception e2) {
System.out.println("关闭流失败");
}
}
}
return byteArray;
}
}

3、重写的类 CustomXWPFDocument

package test1;

import java.io.IOException;
import java.io.InputStream;
import org.apache.poi.openxml4j.opc.OPCPackage;

/**
* 自定义 XWPFDocument，并重写 createPicture()方法
*/
public class CustomXWPFDocument extends XWPFDocument {
public CustomXWPFDocument(InputStream in) throws IOException {
super(in);
}

public CustomXWPFDocument() {
super();
}

public CustomXWPFDocument(OPCPackage pkg) throws IOException {
super(pkg);
}

/**

* @param height 高
* @param paragraph  段落
*/
public void createPicture(int id, int width, int height,XWPFParagraph paragraph) {
final int EMU = 9525;
width *= EMU;
height *= EMU;
String blipId = getAllPictures().get(id).getPackageRelationship().getId();
CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();
String picXml = ""
