SpringBoot 2.x 读取yaml 配置

1. 导入 相关pom config 依赖：

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-configuration-processor</artifactId>
			<optional>true</optional>
		</dependency>

　2.定义私有变量

 

package com.example.bean;

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

import java.util.Date;
import java.util.List;
import java.util.Map;

/**
 *@ConfigurationProperties 告诉springBoot将本类中所有的属性和配置文件中的相关的配置进行绑定
 * prefix = "person" 配置文件中哪个下面的所有属性进行配置，compent 容器一定要注入进去
 */
@Component
@ConfigurationProperties(prefix = "person")
public class Person {

   private String lastName;
   private Integer age;
   private Boolean boss;
   private Date birth;

    @Override
    public String toString() {
        return "Person{" +
                "lastName='" + lastName + '\'' +
                ", age=" + age +
                ", boss=" + boss +
                ", birth=" + birth +
                ", maps=" + maps +
                ", lists=" + lists +
                ", 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 getBoss() {
        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;
    }

    private Map<String,Object> maps;
   private List<Object> lists;  private Dog dog;


}

 

2. 定义私有变量dog

package com.example.bean;

public class Dog {
    private String name;
    private Integer age;

    public Integer getAge() {
        return age;
    }

    public String getName() {
        return name;
    }

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

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

    @Override
    public String toString() {
        return "Dog{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

单测用例

 

package com.example;

import com.example.bean.Person;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Springboot01ApplicationTests {
   @Autowired
   Person person;

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

}
