有个业务场景,业务数据审核通过后需要给用户发短信,发短信过程比较耗时,可能需要几秒甚至十几秒,因此使用异步发短信

使用了注解@Async来实现:

1.SpringApplication启用注解@EnableAsync

@SpringBootApplication
@ImportResource(locations = { "classpath:/spring/spring-*.xml" })
@EnableTransactionManagement(proxyTargetClass=true)
@EnableScheduling
@EnableAutoConfiguration(exclude = { FreeMarkerAutoConfiguration.class })
@EnableSwagger2
@ServletComponentScan(basePackages="com.xx")
@EnableMongoRepositories(basePackages = "com.xx.xx.xx.xx")
@EnableAsync
public class IemsApplication {

	public static void main(String[] args) {
		SpringApplication.run(IemsApplication.class, args);
	}
    ...

2.在业务层(@Service)具体的审核方法上添加注释@Async

@Async
public void cancelAudit(DefectForm defectForm) {
	Map params = new HashMap();
	params.put("defectId", defectForm.getDefectId()); //缺陷记录ID
	params.put("defectStatus", 3); //更新缺陷记录状态审核拒绝
	params.put("reason", defectForm.getReason()); //拒绝理由
	defectRecordDao.updateByPrimaryKeySelective(params);
	
     //上面是业务处理,下面是发短信 //审核拒绝发送短信,短信发送给缺陷上报人,缺陷内容,审核拒绝理由 Account account = accountDao.findAccountById(xxx); if(account != null && StringUtils.isNotBlank(account.getMobile())){ String mobile = account.getMobile(); String defectContent = defectForm.getDefectContent(); String reason = defectForm.getReason(); Map templateData = new HashMap(); templateData.put("defectContent", defectContent); templateData.put("reason", reason); smsService.sendSms(null, mobile, SmsConstant.DEFECT_REFUSRD_CODE, templateData,false); logger.debug("缺陷上报记录审核拒绝,发送短信给缺陷记录上报人******"); } }

3.前端逻辑:

/**
 * 审核拒绝,确定
 * @returns
 */
function makeRefuse(){
	var reason = $("#refuse_reason").val();
	if (reason==null || reason.trim()==""){
		AppUtils.showTooltip("请填写拒绝理由!",false);
		return;
	}
	var curDefect = recordsJson[xxx];
	$.ajax({
		url: path + ‘/xxx/xxx/qqq/cancelAudit‘,
		type: ‘post‘,
		dataType: ‘json‘,
		data:curDefect,
		success: function(data){
			if(data=="ok"){
				AppUtils.showTooltip("审核拒绝成功!",true);
				$("#topForm").attr("action",path + ‘/xxx/xxx/xxx‘);
				$("#topForm").submit();
			}
		}
	});
}

4.Controller层

@RequestMapping("/xxx/xxx/cancelAudit")
@ResponseBody
public String cancelAudit(DefectForm defectForm){
	defectRecordService.cancelAudit(defectForm);
	return "ok";
}

  

经测试,可以异步更新、发送短信

但是,发现一个严重的问题:前台页面点击取消审核后页面状态偶尔能刷新过来,偶尔还是之前的状态,重新查询一次后,页面显示正常

分析代码:Controller层代码写的有问题,Controller层调用Service层(defectRecordService.cancelAudit(defectForm);),Service层cancelAudit(DefectForm defectForm)方法整个是@Async,

主线程会直接返回,而新启的线程处理Service层的逻辑。这样ajax返回前台,前台再去刷新数据的时候,可能新启线程Service的更新逻辑还没处理完,这样就导致了页面刷新状态错误的问题

其实:我们期望的是,业务逻辑(更新操作)执行完成后再返回;整个业务逻辑(更新操作完成,返回)与发短信异步

修改后的代码:

 

1.Controller层

@RequestMapping("/xxx/xxx/cancelAudit")
	@ResponseBody
	public String cancelAudit(DefectForm defectForm){
		defectRecordService.cancelAudit(defectForm); //更新操作,成功后往下走,sendCancelAuditMsg会新启一个线程处理,主线程继续往下走,走到return "ok";返回 
//审核拒绝:业务操作完成后发短信 defectRecordService.sendCancelAuditMsg(defectForm); return "ok"; }

2.Service层

//这里我们就不需要添加异步注解了
public void cancelAudit(DefectForm defectForm) {
		Map params = new HashMap();
		params.put("defectId", defectForm.getDefectId()); //缺陷记录ID
		params.put("defectStatus", 3); //更新缺陷记录状态审核拒绝
		params.put("reason", defectForm.getReason()); //拒绝理由
		defectRecordDao.updateByPrimaryKeySelective(params);
	}

  

//把发短信的逻辑抽出来,单独一个方法,使用异步注解
@Async
public void sendCancelAuditMsg(DefectForm defectForm){
	//审核拒绝发送短信,短信发送给缺陷上报人,缺陷内容,审核拒绝理由
	Account account = accountDao.findAccountById(defectForm.getCreatorUserid());
	if(account != null && StringUtils.isNotBlank(account.getMobile())){
		String mobile = account.getMobile();
		String defectContent = defectForm.getDefectContent();
		String reason = defectForm.getReason();
		Map templateData = new HashMap();
		templateData.put("defectContent", defectContent);
		templateData.put("reason", reason);
		smsService.sendSms(null, mobile, SmsConstant.DEFECT_REFUSRD_CODE, templateData,false);
		logger.debug("缺陷上报记录审核拒绝,发送短信给缺陷记录上报人******");
	}
}

至此问题就解决了,写博客标注一下
