Spring Boot项目中读取yaml配置文件的解决方法

在我的Spring Boot项目中，我有一个POJO类，用于读取yaml配置文件。

@Configuration
@ConfigurationProperties("filenet")
@Data
public class ApplicationConfig {
    @NotNull(message = "Input directory cannot be null")
    @NotBlank(message = "Input directory cannot be blank")
    private String **inputDir**;
    @NotNull(message = "Working directory cannot be null")
    @NotBlank(message = "Working directory cannot be blank")
    private String **workingDir**;
    @Pattern(regexp = "[0-9]+",message = "Invalid value for SMTP port")
    private String port;
}

有时发生inputDir或workingDir或配置文件的其他字段为空的情况。我正在使用javax.validation.constraints检查空白或空值。在这种情况下，以及在启动应用程序时，我会看到一条异常消息，程序终止。例如：Port具有必须为数字的验证。我想做的是妥善处理此异常，并向相关团队发送电子邮件以解决此异常。

我创建了一个用于验证配置文件内容的类

@Component
public class ConfigParamValidation {

    public List<String>  validateApplicationConfigFile(ApplicationConfig applicationConfig) {

        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        Validator validator = factory.getValidator();
        Set<ConstraintViolation<ApplicationConfig.ContentEngine>> contentEngineVoilations = validator.validate(applicationConfig.contentEngine);

        exceptionMessgae = contentEngineVoilations.stream().map(ConstraintViolation::getMessage).collect(Collectors.toList());

        if(!exceptionMessgae.isEmpty()) {
            through new ConfigFileException(<by passing all required params>);
        }
    }
}

我试图创建一个扩展RuntimeException的类

public class ConfigFileException extends RuntimeException {

    private String message;
    private List<String> details;
    private String hint;
    private String nextActions;
    private String support;
    private HttpStatus httpStatus;
    private ZonedDateTime zonedDateTime;

    public ConfigFileException(String message) {
        super(message);
    }

    public ConfigFileException(String message, Throwable cause) {
        super(message, cause);
    }

    public ConfigFileException(String message, Throwable cause, List<String> details, String hint, String nextActions, String support, HttpStatus httpStatus, ZonedDateTime zonedDateTime) {
        super(message, cause);

        this.message = message;
        this.details=details;
        this.hint=hint;
        this.nextActions=nextActions;
        this.support=support;
        this.httpStatus=httpStatus;
        this.zonedDateTime = zonedDateTime;
    }
}

带有@ExceptionHandler的另一个类

@Data
@ControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class SupportTeamException {

    @ExceptionHandler(value = {ConfigFileException.class})
    public ResponseEntity<Object> handleConfigFileException(ConfigFileException e) {
        ConfigFileException configFileException = new ConfigFileException(e.getMessage(), e, e.getDetails(), e.getHint(), e.getNextActions(), e.getSupport(), e.getHttpStatus(), e.getZonedDateTime());
        return new ResponseEntity<Object>(configFileException,e.getHttpStatus());
    }
}

问题是由于某种原因，控件未传递到我可以发送电子邮件的SupportTeamException类。
