Word根据模板生成数据

就是有个模板,完全保留模板样式的情况下,在相应的地方更改或保留数据

第一个类:

 

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Map;
public class WordUtil {
//参数按顺序分别是模板路径,文件输出到的路径,替换的内容
public static void WriteWordByMB(String pathIn,String PathOut,Map<String, Object> changeMap){
try {
WordTemplate template = null;
//先获取模板
File filein = new File(pathIn);
FileInputStream fileInputStream = null;
fileInputStream = new FileInputStream(filein);
template = new WordTemplate(fileInputStream);
//替换模板内容
template.replaceTag(changeMap);
//导出
File fileout = new File(PathOut);
FileOutputStream out;
out = new FileOutputStream(fileout);
BufferedOutputStream bos = new BufferedOutputStream(out);
template.write(bos);

                 fileInputStream.close();
                 out.close();
                 bos.close();

		} catch (Exception e) {
e.printStackTrace();
}
}

}

 

里面调用的另一个类

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.List;
import java.util.Map;

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFTable;

import com.lowagie.text.Document;

/**
 * 仅支持对docx文件的文本及表格中的内容进行替换
 * 模板仅支持 ${key} 标签
 * @author JianQiu
 *
 */
public class WordTemplate {

private static HWPFDocument document;

/**
* 初始化模板内容
* @param inputStream 模板的读取流(doc文件)
* @throws IOException
*/
public WordTemplate(InputStream inputStream) throws IOException{
document = new HWPFDocument(inputStream);
}

public void replaceTag(Map<String, Object> changeMap){
Range range=document.getRange();
for (Map.Entry<String,Object> entry: changeMap.entrySet()) {
range.replaceText("${" + entry.getKey() + "}",
String.valueOf(entry.getValue()));
        }
}

public void write(OutputStream outputStream) throws IOException{
document.write(outputStream);
}
}
 
文件夹不一定存在的话

public static void WriteWordByMB(String pathIn, String pathOut, Map<String, Object> changeMap,                 String FileName) {
  try {
    // 先获取模板
    FileInputStream fileInputStream = new FileInputStream(pathIn);
    WordTemplate template = new WordTemplate(fileInputStream);
    // 替换模板内容
    template.replaceTag(changeMap);
    File f = new File(pathOut);
    // 判断文件夹是否已经存在,如果不存在重新建
    if (!f.exists()) {
      f.mkdirs();
    }


    // 导出
    FileOutputStream out = new FileOutputStream(pathOut + "/" + FileName);
    BufferedOutputStream bos = new BufferedOutputStream(out);
    template.write(bos);
    fileInputStream.close();
    out.close();
    bos.close();
  } catch (Exception e) {
    e.printStackTrace();
  }
}

 

 

以上方法只适用于doc

docx方法可以试试这个(我没试过的……):https://blog.csdn.net/sadwxds/article/details/51331060
