最近在做一个需求，就是根据当前的树形结构，输出到word文档中。下面展示一下小demo
目录
1、输入：
2、输出：文档.docx
3、代码展示
4、测试结果
4.1、模板文档内容
4.2、输出文档
5、总结
1、输入：
root---树节点1
------树节点1.1
------树节点1.2
---树节点2
------树节点2.1
------树节点2.1.1
------树节点2.1.2
------树节点2.1.3
------树节点2.2
2、输出：文档.docx
文档内容：
1、树节点1
树节点1.text
1.1、树节点1.1
树节点1.1.text
1.2、树节点1.2
树节点1.2.text
2、树节点2

3、代码展示
//测试类
public static void main(String[] args) {
//模板文件路径，后续会给出模板文档全部内容
String templatePath = "D:\git_projec\区块对v3.docx";
//输出文档文件路径
String outputPath = "D:\git_project\测试输出v3.docx";
outputToWord(templatePath,outputPath);
}
//文档输出函数

//使用模板中的占位符，就要告诉模板占位符为哪个，即下面map的key值
data.put("titleAndContentList", list);

4、测试结果
4.1、模板文档内容
文档内容如下所示，其中的1、1.1等是设置文章标题级别，自行设置即可，输出的内容格式会被设置成文档中标签的格式。
##章节+文本
{{?titleAndContentList}}
1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1.1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1.1.1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1.1.1.1.1 {{title.titleName}}
{{content}}
{{?titleAndContents}}
1.1.1.1.1.1.1.1 {{title.titleName}}
{{content}}
{{/titleAndContents}}
{{/titleAndContents}}
{{/titleAndContents}}
{{/titleAndContents}}
{{/titleAndContents}}
{{/titleAndContents}}
{{/titleAndContents}}

5、总结
以上就是一个小demo的实现过程，简单记录下，有什么问题可以探讨下。
下面附上poi-tl文档官网，github上也可以搜索到。
最后祝你写代码从头顺到尾！
