属性源文件的内容在某些类中无法识别

Question

当从特定 class.

调用时，@Value 注释不会从属性文件中获取属性

属性配置：

@Configuration
@PropertySource(value = "classpath:s_app.properties")
@PropertySource(value = "classpath:sDBpools.properties")
public class PropertiesConfig {
}

当我从 ProjectInfoServiceImpl class 调用属性时，它 returns 但在 JwtTokenUtil class.

中不起作用

秘密 returns 此处为空：

@Component
@Log4j2
public class JwtTokenUtil implements Serializable {

    private static final long serialVersionUID = -1L;

    private static final int EXPIRATION_MILLISECONDS = 60 * 60 * 1000;

    @Value("${info.app.jwt.secret}")
    private String secret;

    public  String generateToken(User user){
        Map<String, Object> claims = new HashMap<>();
        claims.put("authorities", user.getAuthorities());

        return generateToken(user.getUsername(), claims);
    }

    public  String generateToken(UserDetails userDetails){
        Map<String, Object> claims = new HashMap<>();
        claims.put("authorities", userDetails.getAuthorities());

        return generateToken(userDetails.getUsername(), claims);
    }

    public  String generateToken(String username, Map<String, Object> claims) {

        return Jwts.builder()
                .setSubject(username)
                .setClaims(claims)
                .setExpiration(new Date((System.currentTimeMillis() + EXPIRATION_MILLISECONDS)))
                .setIssuedAt(new Date())
                .signWith(SignatureAlgorithm.HS256, secret)
                .compact();
    }

    public  boolean validateToken(String username, String token){
        return (username.equals(getUsernameFromToken(token)) && !isExpired(token));
    }

    public  String getUsernameFromToken(String token) {
        return getClaimFromToken(token, Claims::getSubject);
    }

    public  Date getExpirationdateFromToken(String token){
        return getClaimFromToken(token, Claims::getExpiration);
    }

    public  boolean isExpired(String token){
        return !(new Date().before(getExpirationdateFromToken(token)));
    }

    public  <T> T getClaimFromToken(String token, Function<Claims, T> claimsResolver) {
        final Claims claims = getAllClaimsFromToken(token);
        return claimsResolver.apply(claims);
    }

    private  Claims getAllClaimsFromToken(String token) {
        return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
    }

}

但在这里 returns 正如预期的那样：

@Service
@Log4j2
public class ProjectInfoServiceImpl implements ProjectInfoService {

    @Value("${info.app.jwt.secret}")
    private String secret;

    @Value("${s.version}")
    private String version;

    @Value("${s.deployment.profile}")
    private String deploymentProfile;

    @Value("${s.deployment.environment}")
    private String deploymentEnvironment;

    @Override
    public ProjectInfoDTO getProjectInfo() {
        ProjectInfoDTO projectInfoDTO = new ProjectInfoDTO();
        projectInfoDTO.setVersion(version);
        projectInfoDTO.setDeploymentProfile(deploymentProfile);
        projectInfoDTO.setDeploymentEnvironment(deploymentEnvironment);
        return projectInfoDTO;
    }
}

文件夹结构如下：

此外，执行器无法从 s_properties 文件的 info.app.version 属性中获取信息。 /info endpoint returns 没有信息，因为它找不到属性.

问题已通过以下问题的批准答案解决。我手动实例化了 JwtTokenUtil class 而不是在调用者 class 中自动装配它。可能我根本没有到达代理对象。
