application.yml文件

#1. properties语法 是Key-Value结构
#1.1 基本写法 key=value  不要写多余的空格
#1.2 propertie 本身就是字符串的数据类型，所以无需添加‘号
#1.3 properties IDEA设定UTF-8 是IDEA读取的字符集编码
#                程序通过ID进行读取时，默认编码ISO-8859-1
#                所以中文必定乱码 需要设定字符集

#2.1  数据结构 key-value结构
#2.2   写法   key：(空格)value
#2.3   yml文件有层级结构   注意父子级语法的缩进
#2.4   yml文件程序默认读取时采用UTF-8编码
