[英]AWS lambda run Spring batch Job from from request handler with out using scheduler
我的应用程序使用带有批处理的spring boot并在aws lambda中对其进行测试,我想以main方法而不是通过Scheduler运行作业。 有可能这样做吗?
@SpringBootApplication
@EnableAutoConfiguration
@EnableJpaRepositories("com.myrepo.repository")
@ComponentScan("com.myrepo")
@EnableScheduling
public class Main {
private static final Logger LOG = LoggerFactory.getLogger(hMain.class);
@Autowired
JobLauncher launcher;
@Autowired
Job job;
public static void main(String[] args) {
try {
LOG.info("Start of application - debt card notofication JOB");
SpringApplication.run(BatchMain.class, args);
} catch (Exception e) {
LOG.error("Exception caught bathch Main, );
}
}
}
编辑-我写了下面的代码,但在AWS Lambda函数内部不起作用
@Scheduled(cron = "0/1 * * * * *")
public void performBatchOpertaion() {
try {
LOG.info("Scheduling Job and Launcher {}, {}", job, launcher);
JobParameters params = new JobParametersBuilder()
.addString(Constants.MYBATCH, String.valueOf(System.currentTimeMillis()))
.toJobParameters();
launcher.run(job, params);
} catch (Exception e) {
LOG.error("Unable to schedules ", e.getCause());
}
}
public static void startApp() {
LOG.info("start batch job ");
SpringApplication.run(Main.class);
LOG.info("end batch job ");
}
这是我的请求处理程序类,它调用Main类的statApp()
--------------------------------------------------------
public class MyHandler implements RequestHandler<Map<String, Object>, String> {
private static final Logger LOG = LoggerFactory.getLogger(MyHandler.class);
@Autowired
BatchMain main;
@Override
public String handleRequest(Map<String, Object> input, Context context) {
LOG.info("Inside the handler request");
BatchMain.startApp();
LOG.info("End of handler request");
return "End Of Application";
}
}
handleRequestmethod等到BatchMain完成。 您可以使用Thread join。 一旦句柄请求返回结果,Lambda执行引擎就会暂停主线程。 在下一个事件中,它可能会完成以前的挂起任务
