spring-cloud-task

问题 I have been looking at using projects built using spring-cloud-task within spring-cloud-dataflow. Having looked at the example projects and the documentation, the indication seems to be that tasks are launched manually through the dashboard or the shell. Does spring-cloud-dataflow provide any way of scheduling task definitions so that they can run for example on a cron schedule? I.e. Can you create a spring-cloud-task app which itself has no knowledge of a schedule, but deploy it to the

问题 I know a cloud task can be scheduled and can be configured using stream also to be executed. As a developer I want to execute my spring cloud task using rest-api so that I can execute the task on demand. Basically i have a work flow management system and we are using control-m agent. So now some of the jobs will be executed by control-m and some of the task will be deployed on spring cloud dataflow server. Now when one job completes then other job which is there on cloud has to be executed.

问题 I have already made a Ingestion job using spring batch which reads xml file and ingest into AEM and its working fine. Now, I am trying to convert this apps into Spring cloud Task. I want to split this apps into 4 different part which is individual apps. I need to connect them into spring cloud data workflow and pass some data and flags based on that next flow will be execute. Is it possible on spring cloud Task? if yes then how can I bind them? please provide some programming tutorial. 回答1:

问题 The Spring cloud dataflow documentation mentions When executing tasks externally (i.e. command line) and you wish for Spring Cloud Data Flow to show the TaskExecutions in its UI, be sure that common datasource settings are shared among the both. By default Spring Cloud Task will use a local H2 instance and the execution will not be recorded to the database used by Spring Cloud Data Flow. I am new to Spring cloud dataflow and spring cloud task. Can somebody help me how to setup a common

问题 I have a task with 2 batch jobs, both jobs run but one of them fails. The status of the particular task is still shown as complete. i read about setting the spring.cloud.task.batch.failOnJobFailure property. When i set this property to true while running the task it gives me the following error: o.s.boot.SpringApplication : Application startup failed java.lang.AbstractMethodError: null at org.springframework.beans.factory.support.AbstractBeanFactory.isSingleton(AbstractBeanFactory.java:402) ~

问题 I am trying to set up SCDF 2.x (Spring Cloud Data Flow) server, to register Spring Boot applications (e.g. Tasks type) , to leverage out of box administration and other capabilities. In setting up SCDF 2.x, was trying to connect to new 'dataflow' schema on Oracle 11.2 (for job registry), but upon starting the dataflow server from command line (with Oracle JDBC in classpath), getting below error. Any suggestions will be helpful to resolve (as we are tied to Oracle as enterprise supported. org
