SpringBoot:ModelAttribute 默认 属性 通过 yml 文件不起作用

SpringBoot: ModelAttribute default property through yml file not working

ModelAttribute 未选择年龄限制默认值,但它与请求参数一起工作正常。

YML 文件

age:            
    default:
        limit:  60  

下面是带有请求参数请求的旧代码

public ResponseEntity<Account> getPersonAccount(@RequestParam String name,@Min(value=0) @RequestParam(required = false, defaultValue = "${age.default.limit}") Integer limit
){
}

下面是带有 ModelAttribute 请求的新代码

public ResponseEntity<Account> getPersonAccount(@ModelAttribute("person" ) Person person) {}

@Configuration
public class Person implements Serializable {
    private String name;
    @Value("${age.default.limit}" )
    private Integer limit;
    getter/setter
}
public class PersonController { 
@Value("${age.default.limit}" )
private Integer limit;

@ModelAttribute("person")
public Person populatePerson() {
    Person person = new Person();
    person.setLimit(limit);
    return user;
}

public ResponseEntity<Account> getPersonAccount(@ModelAttribute("person" ) Person person) {}

}
