Spring Batch Scheduler：Job Listener仅在作业第一次运行时起作用

Question

我正在使用Spring批处理应用程序来使用java配置执行两个批处理作业。 最近我添加了一个Spring调度程序来安排我写的一个Job。 侦听器在作业完成时首次调用，但在下次执行后不会被调用。 以下是我的工作配置的代码：

@Configuration
@EnableBatchProcessing
public class BatchConfiguration{

    @Autowired
    public JobBuilderFactory jobBuilderFactory;

    @Autowired
    public StepBuilderFactory stepBuilderFactory;

    @Autowired
    public MongoTemplate mongoTemplate;

    @Autowired
    UnitsRepository unitsRepos;

    @Autowired
    UserRepository userRepository;

    @Autowired
    ElectraService electraService;

    /*@Autowired InfrastructureConfiguration infrastructureConfiguration;*/

    // tag::readerwriterprocessor[]
    @Bean
    @StepScope
    public MongoItemReader<UserBean> reader() {
        MongoItemReader<UserBean> reader = new MongoItemReader<UserBean>();
        reader.setTemplate(mongoTemplate);
        reader.setCollection("user");
        reader.setQuery("{ '_id': 'U3'}");
        reader.setSort(new HashMap<String,Direction>(){{put("_id", Direction.ASC);}});
        reader.setTargetType(UserBean.class);
        return reader;
    }

    @Bean
    public ExceedUsageProcessor processor() {
        return new ExceedUsageProcessor(unitsRepos,electraService);
    }

    @Bean
    public AnomalyProcessor anomalyProcessor() {
        return new AnomalyProcessor(unitsRepos);
    }
    @Bean
    @StepScope
    public MongoItemWriter<DayByDayUsage> writer() {
        MongoItemWriter<DayByDayUsage> writer = new MongoItemWriter<DayByDayUsage>();
        writer.setTemplate(mongoTemplate);
        writer.setCollection("usage");
        return writer;
    }
    // end::readerwriterprocessor[]

    // tag::listener[]

    @Bean
    @StepScope
    public MongoItemWriter<AnomalyBean> anomalyWriter() {
        MongoItemWriter<AnomalyBean> writer = new MongoItemWriter<AnomalyBean>();
        writer.setTemplate(mongoTemplate);
        writer.setCollection("anomaly");
        return writer;
    }

    @Bean
    public ExceedJobNotificationListener listener() {
        return new ExceedJobNotificationListener(mongoTemplate);
    }

    @Bean
    public AnomalyJobListener anomalyListener(){
        return new AnomalyJobListener(mongoTemplate,userRepository);

    }
    // end::listener[]

    // tag::jobstep[]
    @Bean
    public Job notifyUserJob() {
        return jobBuilderFactory.get("notifyUserJob")
                .incrementer(new RunIdIncrementer())
                .listener(listener())
                .flow(step1())
                .end()
                .build();
    }

    @Bean
    public Job anomalyJob() {
        return jobBuilderFactory.get("anomalyJob")
                .incrementer(new RunIdIncrementer())
                .listener(anomalyListener())
                .flow(step2())
                .end()
                .build();
    }
    @Bean
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .<UserBean, DayByDayUsage> chunk(50)
                .reader(reader())
                .processor(processor())
                .writer(writer())
                .taskExecutor(taskExecutor())
                .throttleLimit(10)
                .allowStartIfComplete(true)
                .build();
    }
    // end::jobstep[]

    @Bean
    public Step step2() {
        return stepBuilderFactory.get("step2")
                .<UserBean, AnomalyBean> chunk(50)
                .reader(reader())
                .processor(anomalyProcessor())
                .writer(anomalyWriter())
                .taskExecutor(taskExecutor())
                .throttleLimit(10)
                .allowStartIfComplete(true)
                .build();
    }

    @Bean
    public TaskExecutor taskExecutor() {
        // TODO Auto-generated method stub
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        taskExecutor.setMaxPoolSize(10);
        taskExecutor.afterPropertiesSet();
        return taskExecutor;
    }

    @Bean
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder()
                .setType(EmbeddedDatabaseType.HSQL)
                .addScript("classpath:/org/springframework/batch/core/schema-hsqldb.sql")
                .build();
    }
}

以下是我的调度程序的代码：

@Component
public class AnomalyScheduler {
     private Job myImportJob;
        private JobLauncher jobLauncher;

        @Autowired
        public AnomalyScheduler(JobLauncher jobLauncher, @Qualifier("anomalyJob") Job myImportJob){
            this.myImportJob = myImportJob; 
            this.jobLauncher = jobLauncher;
       }

       @Scheduled(fixedDelay=60000)
       public void runJob(){
           try {
            jobLauncher.run(myImportJob, new JobParameters());
        } catch (JobExecutionAlreadyRunningException | JobRestartException
                | JobInstanceAlreadyCompleteException
                | JobParametersInvalidException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
       }
}

我的听众如下：

    public class AnomalyJobListener extends JobExecutionListenerSupport {
    private PushNotification pushNotification = PushNotification
            .getPushNotificationInstance();

    @Autowired
    public AnomalyJobListener(MongoTemplate mongoTemplate,
            UserRepository userRepository) {
        List<AnomalyBean> anomalies = new ArrayList<AnomalyBean>(0);
        anomalies = mongoTemplate.findAll(AnomalyBean.class);
        int numAnomalies = anomalies.size();
        List<UserBean> admins = new ArrayList<UserBean>(0);
        admins = userRepository.userByType("admin");
        if (numAnomalies > 0) {
            for (UserBean admin : admins) {
                pushNotification.pushNotification(numAnomalies
                        + " anomalies detected ! Keep an eye on that.",
                        admin.getDeveiceId());
            }

        }
    }
}

这是控制台输出：

请告诉我我做错了什么，为什么听众没有被执行后续尝试。

Answer 1

您只在侦听器构造函数中有代码。 但不是在beforeJob（）afterJob（）或任何其他方法......所以我猜这个监听器被调用但什么也没做......所以你需要覆盖适当的监听器方法。
