利用docx4j完美导出word文档（标签替换、插入图片、生成表格）
【摘要】 最近公司让我实现一个利用原有word模板，导出word文档的功能模块，发现docx4j是个很不错的工具，但是之前从来没有用过，对此并不了解，于是上网查找相关资料，也是非常少之，于是便自己开始摸索。

最近公司让我实现一个利用原有word模板，导出word文档的功能模块，发现docx4j是个很不错的工具，但是之前从来没有用过，对此并不了解，于是上网查找相关资料，也是非常少之，于是便自己开始摸索。
1、原有word模板内容如下：
2、在想要插入数据的地方，插入书签，之后会在代码中获取书签并遍历插入内容。
3、直接上代码。
（1）首先我将word模板文件路径配置在config.properties文件中
-
soil_word_template=/template/soil-report.docx
-
soil_word_filename=soil-report.docx
-
/**

* @param response
-
* @return

@ApiOperation("根据表名统计土壤墒情数据并导出word文档")
-
@RequestMapping(value = "/exportWordReport", method = RequestMethod.POST)
-
@ApiImplicitParams({ @ApiImplicitParam(name = "table", value = "表名",required=false,dataType="query"), @ApiImplicitParam(name="cropDate",value="监测日期",required=false,dataType="query"),
-
@ApiImplicitParam(name = "file", value = "BASE64编码的图片字符",required=false,dataType="query")})
-
public void exportWordReport(String table, String cropDate, String file, HttpServletRequest request,
-
HttpServletResponse response) {
-
// soil_word_template=/template/soil-report.docx
-
// soil_word_filename=soil-report.docx
-
ServletOutputStream out = null;
-
InputStream in = null;
-
File resultFile = null;
-
try {
-
// 土壤墒情word文档模板路径
-
String path = request.getServletContext().getRealPath("") + PropertyUtil.get("soil_word_template");
-
String tempPath = request.getServletContext().getRealPath("");
-
WordprocessingMLPackage wPackage = soilService.exportWordReport(table, cropDate, file, path);
-
// 设置文件属性
-
// wPackage.save(new File("C:\\Users\\admin\\Desktop\\" +
-
// PropertyUtil.get("soil_word_filename")));
-
String fileName = PropertyUtil.get("soil_word_filename");
-
String msg = new String((fileName).getBytes("UTF-8"), "ISO8859-1");
-
response.setContentType("application/msword");
-
response.addHeader("Content-Disposition", "attachment;filename=" + msg);
-
-
// response.setContentType("application/octet-stream");
-
// response.setContentType("application/vnd.ms-excel");
-
response.setCharacterEncoding("UTF-8");
-
// response.addHeader("result", "ok");
-
// response.setContentType("multipart/form-data");
-
out = response.getOutputStream();
-
String strDate = DateUtil.date2String(new Date(), DateUtil.DATE_FORMAT2);
-
resultFile = new File(tempPath + "/tempfile", "soil-report(" + strDate + ").docx");
-
wPackage.save(resultFile);
-
in = new FileInputStream(resultFile);
-
byte[] buffer = new byte[1024];
-
int len = 0;
-
while ((len = in.read(buffer)) > 0) {
-
out.write(buffer, 0, len);
-
}
-
// wPackage.save(out);
-
// wPackage.save(new File("C:\\Users\\admin\\Desktop\\",
-
// "dddd1111.docx"));
-
} catch (Exception e) {
-
Log.error(e);
-
} finally {
-
try {
-
if (out != null) {
-
out.flush();
-
out.close();
-
}
-
if (in != null) {
-
in.close();
-
if (resultFile != null && resultFile.exists() && resultFile.isFile()) {
-
resultFile.delete();
-
}
-
}
-
} catch (IOException e) {
-
// TODO Auto-generated catch block
-
e.printStackTrace();
-
}
-
}
-
}
controller 层中需要注意的地方的是，最开始我用
wPackage.save(out);//直接输出到response的ServletOutPutStream流中，但是这种方式会报错，好像是socket异常之类的问题。
后来改成了代码中的方式，先将文件导出到项目src的webapp文件夹的tempfile文件夹中，然后再从此文件夹中读取该文件，并用out.write()方式输出便能成功执行导出word，前端紧接着下载该word即可。
-
int len = 0;
-
while ((len = in.read(buffer)) > 0) {
-
out.write(buffer, 0, len);
-
}
（3）service层以及serviceImpl层代码
首先来看看咱们需要
是SoilService层代码：
-
/**SoilService层
-
* 根据表名进行统计并导出word报告文档
-
*
-
* @param tableName 表名
-
* @param cropDate 监测日期
-
* @param file base64编码的图片文件字符串
-
* @param path word模板文件路径
-
* @return Map<String, Object>
-
*/
-
WordprocessingMLPackage exportWordReport(String tableName, String cropDate, String file, String path);
然后贴上SoilServiceImpl代码：
-
/**
-
* 根据表名进行统计并导出word报告文档
-
*
-
* @param tableName
-
* @param where
-
* @param file
-
* @return Map<String, Object>
-
*/
