One nice way to do it could be to use a <decision/> element in your flow. The <decision/> would use a Decider implementation that could read from the JobParameters. Then, when you launched the job, you could pass in a parameter to indicate whether the job should continue.

This simplified configuration might get you started:

<job>
    <step id="step1" next="step2"/>
    ...
    <step id="step5" next="continueDecision"/>

    <decision id="continueDecision" decider="continueDecider">
        <next on="CONTINUE" to="step6"/>
        <end on="END"/>
    </decision>

    <step id="step6" next="step7"/>
    ...
    <step id="step10"/>
</job>

<beans:bean id="continueDecider" class="ContinueDecider" scope="step">
    <beans:property name="shouldContinue" value="#{jobParameters[should.continue]}"/>
</beans:bean>

Where the ContinueDecider looks like this:

public class ContinueDecider implements JobExecutionDecider {
    private boolean shouldContinue; //setter omitted

    public FlowExecutionStatus decide(JobExecution jobExecution, StepExecution stepExecution) {
        if (this.shouldContinue) {
            return new FlowExecutionStatus("CONTINUE");
        }
        else {
            return new FlowExecutionStatus("END");
        }
    }
}
