需要的jar包:(具体jar可自行去maven下载)
在这里插入图片描述

注意:需要严格按照上面版本下载jar包,否则可能出现jar包之间不能匹配的导致代码报错

各种 jar包都可以在这里下载:

方法调用:

  1. 导入jar包

  2. 复制以上CustomXWPFDocument类和WorderToNewWordUtils类到项目合适路径(根据自己项目情况判断)

  3. 主类调用方法说明(既以上Test测试类)

  4. 对于一般的字段替换,只需要保持(key,value)的键值对方式赋值替换即可,key和模板占位字符保持一致,例:

    Map<String, Object> data = new HashMap<String, Object>();
    data.put("date","20180306");data.put("{date}", "2018-03-06");data.put("date","20180306");data.put("{name}", “东方明珠”);
    data.put("address","");data.put("{address}", "华东院");data.put("address","");data.put("{communityvalue}", “”);
    data.put("safetycode","");data.put("{safetycode}", "华东院");data.put("safetycode","");data.put("{picture2}", “”);
