我们可以运行一个集成了 Spring Cloud 数据流的 Spring Batch 基于 Web 的应用程序吗？我正在尝试将 SCDF 集成到现有的基于 Web 的 Spring Batch 项目中。这是我的 pom.xml 文件

我的主类用@EnableTask 注释

    package com.TSpringBatch;

    import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.task.configuration.EnableTask;

    @SpringBootApplication
    @EnableBatchProcessing
    @EnableTask
    public class TSpringBatchApplication {
        public static void main(String[] args) {
            SpringApplication.run(TSpringBatchApplication.class, args);
        }
    }

如果我运行应用程序。我收到一条日志消息，

osbceAnnotationConfigEmbeddedWebApplicationContext - 关闭 org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@5fe94a96：启动日期 [Tue Jan 02 16:43:56 IST 2018]；上下文层次的根

所以我的应用程序没有在嵌入式 tomcat 中运行。如果我删除 @EnableTask 注释，它会令人惊讶地工作。请帮我解决这个问题

Spring Cloud Data Flow 不是为嵌入现有应用程序而构建的。它是一个独立的服务器，旨在用作独立的应用程序。
