配置类定义

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.Date;
import java.util.List;
import java.util.Map;

@Component
@ConfigurationProperties(prefix = "test")
@Getter
@Setter
public class TestConfig {

    private String lastName;
    private Integer age;
    private Boolean bool;
    private Date birth;

    private Map<String, Object> maps;
    private Map<String, String> mapb;
    private Map<String, String> maperro;
    private List<Object> lists;
    private Dog dog;

}

import lombok.Data;

@Data
public class Dog {
    private String name;
    private Integer age;
}

yml 配置

test:
  lastName: hello
  age: 18
  bool: false
  birth: 2121/12/12 13:12:11
  maps: {k1: v1,k2: 12}
  mapb:
    aaaa: 哈哈哈
    bbbb: 45644
    cccc: aggdffd
    '2136456': '#123&'
  maperro:
    - eeee: sgdfsgdf
    - eeee-1: 官方大哥发
    - errr_2: 发过的官方
  lists:
    - str1
    - strA
    - 3333
  dog:
    name: 小狗
    age: 12

使用

    @Autowired
    private TestConfig testConfig;

    @ApiOperation( value = "test")
    @GetMapping("/yml")
    public R testYml(){
        return R.ok().put("dd",testConfig);
    }

说明

这样配置yml，取值时候 key会自动带上数字
