springboot如何读取自定义属性

lixl:
  person:
    name: lixl
    age: 20

我们在代码中的属性上，直接注解
/**
 * @author lixl
 * @description
 * @date 2022/2/15
 */
@Component
public class Person {

    @Value("${lixl.person.name}")
    private String name;

    @Value("${lixl.person.age}")
    private String age;

    @Override
    public String toString() {
        return "name:"+this.name+";age:"+this.age;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

	@Value("${lixl.person.name}")
    public void setName(String name) {
        this.name = name;
    }

    public Person(@Value("${lixl.person.name}")String name, @Value("${lixl.person.age}")String age) {
        this.name = name;
        this.age = age;
    }

// 默认是通过 : + 默认值 给定
 public Person(@Value("${lixl.person.name:张三}")String name, @Value("${lixl.person.age}")String age) {
        this.name = name;
        this.age = age;
 }

   @Value("#{'男'}") // 增加性别字段
   private String gender;
	
	// 修改toString方法打印性别
	public String toString() {
        return "name:"+this.name+";age:"+this.age+";gender:"+this.gender;
    }

test.name='lixl'
test.age='age'

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component // 首先本身要是springboot容器中的组件
@ConfigurationProperties(prefix = "test") // 指定前缀
public class ConfigTest {

    private String name;

    private String age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }
}
