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());
    }
}
