二、报错说明

从报错中，定位错误代码

com.project.cloud.thirdparty.api.job.IssueIoIntegralJobHandler.issueIoIntegralJob(IssueIoIntegralJobHandler.java:69)

2.1 定位对应的Service实现类

@Slf4j
@Service
@AllArgsConstructor
public class MailSendService {
private final MailConfigProperties mailConfigProperties;

public void notifyUser(String phone, String email, IoIntegralTask task) {
		String receiver = task.getReceiver();
		String recognizer = task.getRecognizer();
		String medal = MedalLevelEnum.getTxt(task.getMedalLevel());
		BigDecimal integral = task.getIntegral();

		String signName = smsTemplateProperties.getSignName4();
		String templateCode = smsTemplateProperties.getTemplateCode4();
		JSONObject smsTemplateParamJson = new JSONObject();
		smsTemplateParamJson.put("name", receiver);
		smsTemplateParamJson.put("name1", recognizer);
		smsTemplateParamJson.put("medal", medal);
		smsTemplateParamJson.put("num", ObjectUtil.isNotNull(integral) ? StrUtil.toString(integral) : "0");
		try {
			smsUtils.sendSms(signName, phone, templateCode, smsTemplateParamJson.toString());
		} catch (ClientException e) {
			log.error("短信发送失败： e:{}", e);
		}
		if (StrUtil.isBlank(email)) {
			return;
		}
		mailSendService.sendMailByIoIntegral(receiver, recognizer, medal, integral, email);
	}
}

2.2 定位到发邮件的组件

发现账号密码是通过使用配置文件去拿的

	public void sendMailByIoIntegral(String receiver, String recognizer, String medal, BigDecimal integral, String email) {
		MailUtil mailUtil = new MailUtil(mailConfigProperties.getUsername(), mailConfigProperties.getPassword(), mailConfigProperties.getDomain(), mailConfigProperties.getUri());
        HashMap<String, Object> param = new HashMap<String, Object>();
		param.put("to", email);
		param.put("username", "邮件用户略");
		param.put("title", "邮件标题略");
        String msgBody="邮件正文略";
		msgBody = StrUtil.format(msgBody, receiver, recognizer, medal, integral);
		param.put("item", msgBody);
		// 发送邮件
		try {
			mailUtil.sendEmail(param);
		} catch (Exception e) {
			log.error("sendMailByIoIntegral error:{}", e);
		}
	}

2.3 定位到发邮件的工具类

@Slf4j
@Data
public class MailUtil {
    private String username;
    private String password;
    private String domain;
    private String uri;
    
    public MailUtil(String username, String password, String domain, String uri) {
        this.username = username;
        this.password = password;
        this.domain = domain;
        this.uri = uri;
    }
    
    public void sendEmail(Map<String, Object> params) throws Exception {
        // 新建server版本
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
        // 用户名，密码，域名
        ExchangeCredentials credentials = new WebCredentials(username, password, domain);
        service.setCredentials(credentials);
        service.setUrl(new URI(uri));
        VelocityEngine ve = new VelocityEngine();
        ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
        ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
        EmailMessage msg = new EmailMessage(service);
        msg.setSubject(MapUtil.getStr(params, "title"));
        log.info("email params={}", params);
        // 正文
        msg.setBody(MessageBody.getMessageBodyFromText(MapUtil.getStr(params, "item")));
        // 收件人
        msg.getToRecipients().add(MapUtil.getStr(params, "to"));
        msg.send(); // 发送
    }
}

检查Nacos中的邮箱的账号信息

emailinfo:
  username: xxxxx
  password: xxxxx
  domain: xxxxx
  uri: xxxxx

拿这个username+password进远程工具去尝试范围。
我得到了如下提示。

三、报错解决

不用修改代码，直接将账号密码变成长久有效即可。
