问题 I am working on Spring Cloud Data Flow and Spring Batch by taking a reference from https://github.com/spring-cloud/spring-cloud-task/tree/master/spring-cloud-task-samples. I'm executing the batch-job and when executed this example two times, on 2nd time I observed the error, however for the first time it worked fine. I started the spring-cloud-dataflow-server-local server using below commands and it created all metadata for me- highlighted in yellow. Error: exitCode=null, taskName='batch-job'

问题 I'm working on Spring batch and Spring Cloud Data Flow example. In this example, I've developed spring-cloud-data-flow-server and MySQL DB instead of default H2 DB by taking reference from Database Configs for MySQL DB It looks like there is a issue with the Flyways and MySQL version as latest version of Flyways doesn't pickup the latest version of MySQL DB . Error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path

I'm looking to use the Spring Cloud Data Flow , but SCDF doesn't have support for the MongoDB . Is there any way if we can maintain the SCDF Metadata into the Postgres (as

问题 I'm working on Spring batch and SCDF example. In this example I am reading CSV file and loading all the data to MySQL . I was able to successfully load the data into MySQL DB, but but UI doesn't show me START_TIME and END_TIME , even db doesn't holds any records. I've uploaded my code here: https://github.com/JavaNeed/spring-cloud-dataflow-example1.git spring-cloud-data-flow-server SpringCloudDataFlowServerApplication.java @EnableDataFlowServer @SpringBootApplication(exclude = {

问题 I created a custom Spring Cloud Stream Processor Application and deployed it as the processor step in a Source|Processor|Sink stream. Everything seems to be working fine, but my custom app shows "deploying" in the dataflow UI. I'm deploying it as a SNAPSHOT from mavenLocal if that affects anything. Am I missing something to let SCDF know the deployment was successful? 回答1: The usual culprit, in this case, is the unavailability of Boot's actuator endpoints at runtime. More specifically, it is
