Java利用poi生成word(包含插入图片，动态表格，行合并)
测试模板样式：
Word生成结果：
图表 2
需要的jar包：（具体jar可自行去maven下载）
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：
-
导入jar包
-
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）
-
主类调用方法说明(既以上Test测试类)
-
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","2018−03−06");data.put("{date}", "2018-03-06");data.put("date","2018−03−06");data.put("{name}", “东方明珠”);
data.put("address","华东院");data.put("{address}", "华东院");data.put("address","华东院");data.put("{communityvalue}", “”);
data.put("safetycode","华东院");data.put("{safetycode}", "华东院");data.put("safetycode","华东院");data.put("{picture2}", “”);
data.put("利用POI 技术动态替换word模板内容
