springboot配置文件绑定实现解析

先创建一个peron类，然后需要注解configurationProperties（prefix ="person"）<br data-filtered="filtered">然后需要加一个@component<br data-filtered="filtered">因为只有在springboot的容器才能提供容器提供的@configurationProperties<br data-filtered="filtered">@Component
@ConfigurationProperties(prefix = "person")
public class Person {
  private String lastName;
  private Integer age;
  private boolean boss;
  private Date birth;
  private Map<String,Object> maps;
  private List<Object> lists;
  private Dog dog;
  public String getLastName() {
    return lastName;
  }
  public void setLastName(String lastName) {
    this.lastName = lastName;
  }
  public Integer getAge() {
    return age;
  }
  public void setAge(Integer age) {
    this.age = age;
  }
  public boolean isBoss() {
    return boss;
  }
  public void setBoss(boolean boss) {
    this.boss = boss;
  }
  public Date getBirth() {
    return birth;
  }
  public void setBirth(Date birth) {
    this.birth = birth;
  }
  public Map<String, Object> getMaps() {
    return maps;
  }
  public void setMaps(Map<String, Object> maps) {
    this.maps = maps;
  }
  public List<Object> getLists() {
    return lists;
  }
  public void setLists(List<Object> lists) {
    this.lists = lists;
  }
  public Dog getDog() {
    return dog;
  }
  public void setDog(Dog dog) {
    this.dog = dog;
  }
  @Override
  public String toString() {
    return "Person [lastName=" + lastName + ", age=" + age + ", boss=" + boss + ", birth=" + birth + ", maps="
        + maps + ", lists=" + lists + ", dog=" + dog + "]";
  }
   
}

public class Dog {
  private String Name;
  private Integer age;
  public String getName() {
    return Name;
  }
  public void setName(String name) {
    Name = name;
  }
  public Integer getAge() {
    return age;

  public void setAge(Integer age) {
    this.age = age;
  }
  @Override
  public String toString() {
