SpringBoot从Yml文件读取配置

注解方法

@ConfigurationProperties(prefix = "spring.arr")
@Data

注意@Data注解，从Yml读取配置映射到类上时一定要有set方法，不然读不到。

从Yml文件读取列表

spring:
  arr:
    pinfo:
      - name: gaf11
        age: 11
        school: scu

      - name: gaf22
        age: 22
        school: scu

      - name: gaf33
        age: 33
        school: scu

@Data
public class Pinfo {
    String name;
    Integer age;
    String school;
}

@ConfigurationProperties(prefix = "spring.arr")
@Component
@Data
public class ReadArr {
    List<Pinfo> pinfo;
    ReadArr(){}
    public List<Pinfo> getList(){
        return pinfo;
    }
}
