SpringMVC集成SpringBatch事务有问题

标签: java spring-mvc spring-boot spring-batch

springbatch集成了mvc导入接口后,事务异常,并且将服务层注入到作业中以执行事务问题。 BatchController.class

    @RestController
    @RequestMapping(value = "/job")
    public class BatchController {

        private final JobLauncher jobLauncher;

        private final Job batchGenerateJob;

        @Autowired
        public BatchController(JobLauncher jobLauncher, Job batchGenerateJob) {
            this.jobLauncher = jobLauncher;
            this.batchGenerateJob = batchGenerateJob;
        }

        @GetMapping(value = "/{cid}")
        public AjaxObj batchgenbycid(@PathVariable String cid) {
            if (StringUtils.isBlank(cid) || Integer.parseInt(cid) == 0) {
                return ResultUtil.fail("请在左侧点击栏目");
            }
            JobParameters jobParameters = new JobParametersBuilder()
                    .addString("channelId", cid)
                    .addString("siteId", Integer.toString(1))
                    .addString("runtime", "最后执行时间:" + DateFormatUtils.format(new Date(), "yyyy_MM_dd_HH_mm_ss"))
                    .toJobParameters();
            try {
                jobLauncher.run(batchGenerateJob, jobParameters);
            } catch (JobExecutionAlreadyRunningException e) {
                e.printStackTrace();
            } catch (JobRestartException e) {
                e.printStackTrace();
            } catch (JobInstanceAlreadyCompleteException e) {
                e.printStackTrace();
            } catch (JobParametersInvalidException e) {
                e.printStackTrace();
            }
            return ResultUtil.success();
        }
    }
