[Java知识库]Spring yaml

1.基本语法

2.数据类型



3.实际演示

（1）Person中的配置如下

@Data
@ToString
@Component //和绑定application.properties是一样的意思，放进容器中使用Springboot的功能
@ConfigurationProperties(prefix = "person")
public class Person {
    private String name;
    private Integer age;
    private Boolean boss;
    private Date birthday;
    private Pet pet;
    private String [] interests;
    private List<String> animals;
    private Set<Double> salary;
    private Map<String,Object> score;
    private Map<String,List<String>> allPets;
}

（2)Pet中的配置如下

@Data
@ToString
public class Pet {
    private String p_name;
    private Double weight;
}

（3）application.yaml中的配置如下

person:
  name: malong
  age: 21
  boss: true
  birthday: 1452/5/6
  #interests: [篮球,羽毛球]
  interests:
    - 篮球
    - 足球
    - 15
  animals: [羊儿,猫]
  #score:
    #english: 99
    #math: 100
  score: {english:100,math:99}
  salary:
    - 898888
    - 455555
  pet:
    p_name: tom
    wejght: 4
  allPets:
    sick:
      - {p_name:龙,welght:22}
      - p_name: 虎
        weight: 583
      - p_name: 咪咪
        weight: 10
    healthy:
      #- [{p_name:ma,weight:25},{p_name:ml,weight:25}]
      - {p_name:ma,weight:25}
      - {p_name:ml,weight:25}

（4）controller中的配置如下

@RestController
public class hello_controller {

    @Autowired
    Person  person;
    @RequestMapping("/hello")
    public Person person(){
        return person;
    }
}

（5）启动主程序验证即可成功
