Caused by: org.yaml.snakeyaml.parser.ParserException: while parsing a block mapping ：yam文件报错解决

person: "一号"
  age: 10
  name: "老王"

以上为yam文件片段，springboot运行时，会报以下错误：

原因分析：

yam文件有较为严格的格式，格式不正确就无法正常解析。由于本人也是第一次使用yam文件，不懂其规则。经百度才知道当该节点还有其他子节点时，该父节点不能有值。

解决方法，改成一下格式即可：

person: 
  age: 10
  name: "老王"
