## 1、application.yml配置文件 ##

user:
      username: zhangsan
      age: 18
      sex: 男

## 2、编写一个配置类 ##

package com.xiaomin.wechat_brn.confing;
    
    import lombok.Data;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.stereotype.Component;
    
    @Data
    @Component
    @ConfigurationProperties(prefix = "user")
    public class UserConfiguration {
        private String username;
        private int age;
        private String sex;
    }

## 3、测试 ##

注意：@RunWith(SpringRunner.class)需要导入junit4依赖

package com.xiaomin.wechat_brn.confing;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class UserConfigurationTest {
    
        @Autowired
        private UserConfiguration userConfiguration;
    
        @Test
        public void fun(){
            System.out.println(userConfiguration.getUsername());
        }
    }

## 4、测试结果 ##
