CallableTaskletAdapter Spring Batch

Question

CallableTaskletAdapter是否使用与步骤本身不同的线程？

    @Bean
    public Callable<RepeatStatus> callableObject() {

        return () -> {
            System.out.println(Thread.currentThread().getName());
            System.out.println("This was executed in another thread");

            return RepeatStatus.FINISHED;
        };
    }

    @Bean
    public CallableTaskletAdapter tasklet() {
        CallableTaskletAdapter callableTaskletAdapter =new CallableTaskletAdapter();

        callableTaskletAdapter.setCallable(callableObject());

        return callableTaskletAdapter;
    }
@Bean
    public Step callableStep() {
        System.out.println(Thread.currentThread().getName());
        return this.stepBuilderFactory.get("callableStep")
                .tasklet(tasklet())
                .build();
    }

运行此代码在可调用的tasklet中将线程名称打印为“ main”。这意味着它没有使用新线程。我想念什么吗？
