概念

比如我的yml中写的last-name,这个和lastName是一样的，-后面跟着的字母默认是大写的，这就是松散绑定

示例

类代码：

public class Person {

    private String lastName;
    private Integer age;
    private Boolean happy;
    private Date birth;
    private Map<String,Object> maps;
    private List<Object> lists;
    private Dog dog;

// 有参、无参、Getter和Setter方法、toString()

yml配置：

person:
  last-name: ZuY
  age: 18
  happy: false
  birth: 2000/01/01
  maps: {k1: v1,k2: v2}
  lists:
    - code
    - girl
    - music
  dog:
    name: 旺财
    age: 5

测试代码：

@SpringBootTest
class Demo1ApplicationTests {

    @Autowired
    private Person person;

    @Test
    void contextLoads() {
        System.out.println(person);
    }

}

结果：
