java poi给word（2007及以上）的书签动态替换文字、图片（可浮于文字上方）
一、因为原本的XWPFDocument类插入图片方法有bug，要么打不开word，要么打开了不显示图片，所以新建一个CustomXWPFDocument类继承XWPFDocument，重写插入图片方法。
二、插入到指定位置（书签）是获取所有段落、所有表格，遍历获取到的每一个段落（表格可以获取到cell后再获取cell里的段落），段落通过paragraph.getCTP().getBookmarkStartList()获得所有的书签，匹配需要的书签创建run，然后把图片添加到创建的run中。
三、插入图片默认为嵌入型，这里提供浮于文字上方方法（把anchor标签下的behindDoc属性设为0，同时添加一个
四、其中main方法里为启动方式
五、完整代码如下：
