准备替换实体：
@Data
@Builder
public class ReplaceParam {
//占位符
private String placeholder;
//替换值
private String replaceValue;
//默认值
private String defaultValue;
//文字大小
private Integer size;
//字体样式
private String fontFamily;
//字体颜色
private String color;
//..........
}
具体实现：
public class POIWordUtil {

//创建文档
XWPFDocument xwpfDocument = DocUtil.create(sourceFile);
try (FileOutputStream outputStream = new FileOutputStream(targetFile)) {

}
//表格
if (iBodyElement instanceof XWPFTable) {

原始模板：
替换后：
注意
如果出现${替换符}出现没在一起的情况，像这种：
解决办法：
把 ${替换符} 先在记事本上连续写出来，再粘贴到文档中
