idea中创建springboot中用@Value读取.yml文件无法读取里面的数据

Question

   studenting:
     id:1
     name:liuyupeng

这个是application.yaml文件中的数据

然后测试

package com;

import com.domain.Student;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Ch1101SpringbootApplicationTests {

	@Autowired
	private Student student;
	@Test
	void contextLoads() {
		System.out.println(student);
	}

}

结果报错

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'student': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'studenting.name' in value "${studenting.name}"

我的yaml文件都是有叶子图标的
 

Answer 1

你这个yaml配置好像有点问题吧，要严格按照yaml的语法了，这是个将空格用到极致的语法。

试下：注意冒号后面的空格

studenting:

id: 1

name: liuyupeng
