嗨，我是Spring批处理的新手，并且遇到了以下无法解决的异常：

java.lang.IllegalStateException: Failed to execute CommandLineRunner

我的代码在这里：

    @SpringBootApplication
    public class BatchDemo {
    public static void main(String args[])
    {
        SpringApplication.run(BatchDemo.class);
    }
}

我可以通过添加解决它exclude = BatchAutoConfiguration.class。但我想找出实际原因并解决它。

我没有传递任何命令行参数，并且这种情况不会一直发生。
