IDEA环境Springboot2.2.1进行Web开发，自定义pesonal.yml文件读取不到value值

Question

先看下文件位置：

文件内容如下：

jwt:
  # 加密私钥
  secret: bensu[sentiment]
  # header名称
  header: token
  # 有效时长7天（7*24*60*60）
  expire: 604800

绑定实体类代码如下：

@Component
@PropertySource("classpath:personal.yml")
@ConfigurationProperties(prefix = "jwt")
public class TokenDomain {
    // header名称
    @Value(value = "${header}")
    private String header;
    // 密钥
    @Value(value = "${secret}")
    private String secret;
    // 有效时长
    @Value(value = "${expire}")
    private long expire;

    public String getHeader() {
        return header;
    }

    public void setHeader(String header) {
        this.header = header;
    }

    public String getSecret() {
        return secret;
    }

    public void setSecret(String secret) {
        this.secret = secret;
    }

    public long getExpire() {
        return expire;
    }

    public void setExpire(long expire) {
        this.expire = expire;
    }
}

调用该实体类代码如下：

    @Autowired
    private TokenDomain tokenDomain;
    /**
     * 根据身份ID标识，生成Token
     * @param userId 根据身份ID标识
     * @param pwd 密码
     * @return Token 字串
     */
    public String createToken(String userId,String pwd){

        //过期时间,精确到毫秒
        Date expireDate = new Date(new Date().getTime() + tokenDomain.getExpire());

        // 生成token字串
        String token =Jwts.builder()
                .setHeaderParam("typ","JWT")
                .setHeaderParam("alg","HS256")
                .claim("userId",userId)
                .claim("pwd",pwd)
                .setSubject(userId+pwd)
                .setIssuedAt(new Date())
                .setExpiration(expireDate)
                .signWith(SignatureAlgorithm.ES512, tokenDomain.getSecret())
                .compact();
        return token;
    }

实体类在Spring测试类中可正常读取：

    @Autowired
    TokenDomain token;
    @Test
    void getPersonal(){
        System.out.println(token);
        System.out.println(token.getHeader());
        System.out.println(token.getSecret());
        System.out.println(token.getExpire());

    }

测试类返回结果如下：

但是，业务逻辑类一直都无法正常读取内容，domain一直为null

请高手指点迷津。

去掉@PropertySource和@Value注解，这两个多余的，用@Value注解前缀也要加上
