JAVA下载word(可保留模板样式)

JAVA下载word(可保留模板样式)

本文讲述读取word模板的制作和模板读取动态插入数据生成word

1.首先制作模板

找我们需要的word模板文件,打开他,然后选另存为,保存成XML格式


然后用Notepad++打开对应的XML,用XML Tools插件序列化数据(插件下载地址: 点这.)

序列化后处理数据占位符,删除${}包裹的中间不需要的格式标签字符.
然后保存,模板制作完成.

2.数据结合模板调用API生成文档实现下载

步骤大致如下:
1.设置下载响应头
2.处理数据,数据格式一般为Map<String,Object>格式
3.调用 freemarker的API方法完成下载.
参考代码如下:

//controller部分@RequestMapping(value = "download/{caseId}", method = RequestMethod.GET)public void downloadSimilarCase(HttpServletRequest request, HttpServletResponse response,@RequestParam(value = "caseNo", required = false, defaultValue = "") String caseNo,@PathVariable("caseId") String caseId) throws UnsupportedEncodingException {// 文件名caseNo = URLDecoder.decode(caseNo, "utf-8");String fileName = Header("User-Agent"), caseNo + ".doc");SimilarCaseById(response, caseId, fileName);}

//service实现部分public void getSimilarCaseById(HttpServletResponse response, String caseId, String fileName) {//response.setContentType("application/vnd.ms-word;charset=UTF-8");response.setContentType("application/msword;charset=UTF-8");response.addHeader("Content-Disposition", "attachment;filename=" + fileName);response.setHeader("Content-Type", "application/force-download");response.setCharacterEncoding("utf-8");//condition 为动态写入的数据,他的键是占位符${}中介的字符,他的值就是对应需要替换改占位符的数据Map<String, Object> condition = new HashMap<>();condition.put("caseId", caseId);Object result = getSimilarCaseById(condition);//调用方法获取数据,具体内容无需展开,自己按自己需求处理数据为Map<String, Object>格式即可Map<String, Object> lawCase = null;if(result instanceof Map) {lawCase = (Map<String, Object>)result;}//这是清理脏数据的,如果你动态写入的内容里有一些特殊字符比如&,#等,可能会导致生成的文档无法打开,所以这里进行处理下removeSpecChar(lawCase);//这里就是拿处理好的数据和response相应流去实现浏览器响应下载,具体后面会展开说ate(response, lawCase);}

// ate(response, lawCase)方法详细内容

//这就是给文字加样式格式的方法,将文字content加上上面标签再返回,到时候这一大串都会替换原来的占位符,成功进入xml文档,然后就能样式和文字生效展示
