java - 是否可以从Spring Batch的JobExecutionContext访问Tasklet

Question

我试图取消小线程的执行，而不取消整个步骤/作业。我已经以可以根据标志取消它的方式实现了该tasklet。但是JobExecutionContext没有提供任何媒介来访问tasklet？有没有办法访问tasklet实例？

Answer 1

这可以通过决策者实现

    public class MyDecider implements JobExecutionDecider {


    @Override
    public FlowExecutionStatus decide(JobExecution jobExecution, StepExecution stepExecution) {

        if (condition) {
        // choose what ever you want to do 
        return new FlowExecutionStatus("");    

            }
        // choose what ever you want to do 
        return new FlowExecutionStatus("");
    }
}
