02-SpringBoot加载配置文件属性

1.单独属性中读取

//配置类原文
china:
  compony:
    name: 畅由
    adress: 深圳
    email: 23048043980
//单独读取属性
@Value("${china.compony.nam}") String name;

2.创建配置类对象

@ConfigurationProperties(prefix = "china.compony")
public class ComponyConfig {
    private String name;
    private String adress;
    private String email;

}
