}

测试结果 #

相关代码实现 #

EmailController类代码 #

@RequestMapping("/app/Email")
@RestController
public class EmailController {

    private Logger log = LoggerFactory.getLogger(EmailController.class);

    @Autowired
    EmailService emailServices;

    @PostMapping(value = "/saveAsDraft")
    public ResponseEntity<Object> saveAsDraft(@RequestBody EmailConfiguration emailConfiguration, HttpServletRequest httpRequest) {

        if (!emailServices.validateEmailConfiguration(emailConfiguration)) {
            return ResponseEntity.badRequest()
                    .body(ApplicationConstants.INVALID_REQUEST);
        }

        String currentStatus = "";
        try {
            // 调用GraphService保存草稿
            currentStatus = emailServices.saveAsDraft(emailConfiguration, httpRequest);

        } catch (Exception e) {
            log.error("Error saving as draft for processinstanceid : {}" , emailConfiguration.getProcessinstanceid());
            return ResponseEntity.internalServerError()
                    .body(ApplicationConstants.ERROR_SAVING_DRAFT);
        }
        return ResponseEntity.ok(currentStatus);
    }
}

邮箱配置验证方法（EmailService实现类） #

@Override
public boolean validateEmailConfiguration(EmailConfiguration config) {
    try {
        if(StringUtils.isBlank(config.getProcessinstanceid()) 
                || StringUtils.isBlank(config.getSubject())
                || StringUtils.isBlank(config.getMailFrom())
                || StringUtils.isBlank(config.getMailTo())
                ) {
            return false;
        }
    } catch(Exception e) {
        log.error("Validation of email configuration failed :{}, {}",e.getMessage(),e);
        return false;
    }
    return true;
}

核心疑问 #

当前使用的processinstanceid值为DefaultProcessID，但无法确定该参数的合法取值范围或正确值，导致调用接口时触发500错误，需明确该参数的正确输入规则或有效值来源。
