java 根据word xml模板生成word(个人v2版本)

这里用的是poi相关jar包以及freemarker插值技术实现，poi相关jar包这里不再述说

1，编辑word并保存为xml

其中需要动态输出的内容使用${xxx}代替，xxx是你的java类属性值，如：年龄：${age}
打开的xml要看看是否为途中${}的样式，如果被wold分割了，需要自己了解wold xml格式并去修改

2，把xml后缀改为ftl文件

 

    $(function() {
         //导出
           $("#exportWordData").click(function() {  
               var id = $("input[name='id']").val();
             //  alert(id);
               var url = __ctx+'/yjsqsgyrb/yjsqsgyrb/yjsqsgyrb/exportWordxml.ht?id='+id;
               var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串
               if (userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1) {//判断是否IE浏览器
                   window.location.href(url);
               }else{
                   window.open(url,"xxx调度日报_");
               }
           });
    });

 

@RequestMapping("exportWordxml")
    public void exportWordxml(HttpServletRequest request, HttpServletResponse response) throws Exception {
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        Map<String, Object> rootMap = new HashMap<String, Object>();
        String id = RequestUtil.getString(request, "id");

        Yjsqsgyrb yjbb = new Yjsqsgyrb();
        yjbb = (Yjsqsgyrb) yjsqsgyrbService.getById(Long.valueOf(Long.parseLong(id)));
        
        Gson gson = new Gson();
        String json = gson.toJson(yjbb);
        rootMap = gson.fromJson(json, rootMap.getClass());

        String name = "xxx日报_" + df.format(new Date()) + ".doc";
        // 设置MIMI类型，默认的是text/hmtl
        response.setHeader("Content-Type", "application/msword");
        // 解决中文乱码，以及设置生成的文档名
        response.setHeader("Content-Disposition", "attachment;filename=" + new String(name.getBytes("utf-8"), "ISO8859-1"));

        // 取得当前类所在的目录
        String filePath = FileUtil.getRootPath() + File.separator + "commons" + File.separator + "template" + File.separator + "yjdlbb" + File.separator;

        Configuration cfg = new Configuration();
        cfg.setDirectoryForTemplateLoading(new File(filePath));

        // 这里不设置编码的话，即是成功了有时也打不开文件，因为乱码
        Template temp = cfg.getTemplate("myxml.ftl", "utf-8");
        PrintWriter pw = response.getWriter();

        /* 合并数据模型和模版 */
        temp.process(rootMap, pw);
        pw.flush();
        pw.close();
    }

 

其中导入的类

import com.google.gson.Gson;
import freemarker.template.Configuration;
import freemarker.template.Template;

 

若需要修改其中的值，可以直接修改map中的json即可，比如同比需要判断数字大于零在前面添加增长，小于零则在前面添加减少

        Map<String, Object> rootMap = new HashMap<String, Object>();
        String id = RequestUtil.getString(request, "id");

        Yjsqsgyrb yjbb = new Yjsqsgyrb();
        yjbb = (Yjsqsgyrb) yjsqsgyrbService.getById(Long.valueOf(Long.parseLong(id)));
        
        Gson gson = new Gson();
        String json = gson.toJson(yjbb);
        rootMap = gson.fromJson(json, rootMap.getClass());
        Object object = rootMap.get("qstdzgfhhb");
        if (object!=null) {
            Double double1 = (Double) object;
            if (double1!=null&&double1>0) {
                rootMap.put("qstdzgfhhb", "增加"+double1);
            }else if (double1!=null&&double1<0) {
                rootMap.put("qstdzgfhhb", "减少"+Math.abs(double1));
            }
//            System.out.println("-----------"+double1);
        }

 

/**
     * @param rootMap 
     * void   调用 rootMap =yjsqsgyrbService.handleVar(rootMap);
     * 
     */
    public Map<String, Object>  handleVar(Map<String, Object> rootMap) {
        java.util.List<String> vars = new java.util.ArrayList<String>();
        vars.add("qstdzgfhhb");
        vars.add("hbsrzj");
        vars.add("rydlhb");
        vars.add("yljydltb");
        vars.add("nljydltb");

        for (String key : vars) {
            Object object = rootMap.get(key);
            if (object != null) {
                Double double1 = (Double) object;
                if (double1 != null && double1 > 0) {
                    rootMap.put(key, "增加" + double1);
                } else if (double1 != null && double1 < 0) {
                    rootMap.put(key, "减少" + Math.abs(double1));
                }
            }

        }
        return rootMap;
    }
