yaml语法讲解（2）

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

 新建一个Person.java,写完Person类之后再在整个类上加上注解:

@Component
@ConfigurationProperties(prefix = "person")

package com.kuang.pojo;
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 = "person")
public class Person {

    private String name;
    private Integer age;
    private Boolean happy;
    private Date birth;
    private Map<String,Object> maps;
    private List<Object> lists;
    private Dog dog;
    public Person(){
    }
    public Person(String name,Integer age,Boolean happy,Date birth,Map<String,Object> maps,List<Object> lists,Dog dog){
        this.age=age;
        this.birth=birth;
        this.dog=dog;
        this.happy=happy;
        this.lists=lists;
        this.maps=maps;
        this.name=name;
    }

    public void setName(String name) {
        this.name = name;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public Integer getAge() {
        return age;
    }
    public String getName() {
        return name;
    }
    public Boolean getHappy() {
        return happy;
    }

    public Date getBirth() {
        return birth;
    }

    public Dog getDog() {
        return dog;
    }

    public List<Object> getLists() {
        return lists;
    }

    public Map<String, Object> getMaps() {
        return maps;
    }

    public void setBirth(Date birth) {
        this.birth = birth;
    }

    public void setDog(Dog dog) {
        this.dog = dog;
    }

    public void setHappy(Boolean happy) {
        this.happy = happy;
    }

    public void setLists(List<Object> lists) {
        this.lists = lists;
    }

    public void setMaps(Map<String, Object> maps) {
        this.maps = maps;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + ''' +
                ", age=" + age +
                ", happy=" + happy +
                ", birth=" + birth +
                ", maps=" + maps +
                ", lists=" + lists +
                ", dog=" + dog +
                '}';
    }
}

给对应的属性赋值：application.yaml文件

person:
  name: qinjing
  age: 3
  happy: false
  birth: 2019/11/20
  maps: {k1: v1,k2: v2}
  lists:
    - code
    - music
    - girl

  dog:
    name: 旺财
    age: 3

对应输出的测试类：

package com.kuang;

import com.kuang.pojo.Dog;
import com.kuang.pojo.Person;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Springboot02ConfigApplicationTests {

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

}
