1、导入依赖呀
<!--导入配置文件处理器 配置文件进行绑定就会有提示--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> </dependency>
2、创建配置类
package com.atguigu.controller.bean; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; import java.util.List; import java.util.Map; /** * @author houChen * @date 2020/6/14 22:36 * @Description: */ /** * ConfigurationProperties: * 将配置文件中每一个属性的值,都映射到这个组件中 * @ConfigurationProperties : 告诉SpringBoot将本类中的所有属性 和配置文件中相关的配置进行绑定 * prefix = "person" ==》指定类中的属性和配置文件中哪个下面的属性进行一一配置 * * 配置类必须是容器中的组件 */ @Component @ConfigurationProperties(prefix = "person") public class Person { private String lastName; private Integer age; private Boolean boss; 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 getBoss() { return boss; } public void setBoss(Boolean boss) { this.boss = boss; } 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; } }
3、在yml编写相应的配置
person: last-name: zhangsan age: 18 boss: false birth: 2018/12/12 maps: {k1: v1,k2: v2} lists: - lisi - wangwu dog: name: uzi afe :20
效果:
