将map转换为YAML

 因为项目学习，看了一堆别人写的，运行出来出现一些花里胡哨的东西，所以自己就研究了一下，有用到数组，相对比较全。有问题欢迎提问。

用到的依赖：

<!-- json -->
<dependency>
    <groupId></groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.66</version>
</dependency>
<!--json 转 yml -->
<dependency>
   <groupId></groupId>
   <artifactId>jackson-dataformat-yaml</artifactId>
   <version>2.9.0.pr4</version>
</dependency>
