使用taskExecutor（asyncTaskExecutor（））时停止spring批处理中的线程

我这里有个问题。当我在spring批处理配置中将其用作我的代码（如下）时，我的代码将成功结束

@Bean(name = "myStep")
public Step myStep() {
    int cores = Runtime.getRuntime().availableProcessors(); 
    int maxAndQueueSize = cores * 2;
    return stepBuilderFactory.get("myStep").<A, B> chunk(CHUNKS)
            .reader(myItemReader(entityManagerFactory)).processor(myProcessor())
            .writer(myWriter()).listener(myListener()).throttleLimit(maxAndQueueSize).allowStartIfComplete(true).build();
}

这是asyncTaskExecutor（）

@Bean(name = "myStep")
public Step myStep() {
    int cores = Runtime.getRuntime().availableProcessors(); 
    int maxAndQueueSize = cores * 2;
    return stepBuilderFactory.get("myStep").<A, B> chunk(CHUNKS)
            .reader(myItemReader(entityManagerFactory)).processor(myProcessor())
            .writer(myWriter()).listener(myListener()).taskExecutor(asyncTaskExecutor()).throttleLimit(maxAndQueueSize).allowStartIfComplete(true).build();
}

@Bean(name = "asyncTaskExecutor")
public AsyncTaskExecutor asyncTaskExecutor() {
    int cores = Runtime.getRuntime().availableProcessors(); 
    int maxAndQueueSize = cores * 2;
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setCorePoolSize(cores);
    executor.setMaxPoolSize(maxAndQueueSize);
    executor.setQueueCapacity(maxAndQueueSize);
    executor.setThreadNamePrefix("asyncExecutor-");
    executor.initialize();
    return executor;
}
