java 使用word模板生成word

一：导入jar

可能用不到这么多

   org.apache.poi
   poi
   3.9



   org.apache.poi
   poi-ooxml
   3.15



   org.apache.commons
   commons-lang3
   3.4



   org.apache.poi
   poi-scratchpad
   3.9



   commons-io
   commons-io
   2.4


   commons-fileupload
   commons-fileupload
   1.3.2

二：新建一个word文档

三：存放地址

四：代码

public class DocUtil {
    private static Logger log=Logger.getLogger(DocUtil.class);

    public static void main(String[] args) {
        Map map=new HashMap();
        map.put("ar_cp_name","月报");
        map.put("ar_dateTime","2018-5-28");
        map.put("ar_info","岁的法国大使馆的风格");
        getBuild("static/doc/ar_template.doc",map,"D:/aaa.doc");
    }

    public static void getBuild(String  tmpFile, Map, String> contentMap, String exportFile){

        InputStream inputStream = DocUtil.class.getClassLoader().getResourceAsStream(tmpFile);
//        InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream(tmpFile);
        HWPFDocument document = null;
        try {
            document = new HWPFDocument(inputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 读取文本内容
        Range bodyRange = document.getRange();
        // 替换内容
        for (Map.Entry, String> entry : contentMap.entrySet()) {
            bodyRange.replaceText("${" + entry.getKey() + "}", entry.getValue());
        }

        //导出到文件
        try {
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            document.write(byteArrayOutputStream);
            OutputStream outputStream = new FileOutputStream(exportFile);
            outputStream.write(byteArrayOutputStream.toByteArray());
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
 }

五：结果
