What does loading process do? It takes more than 20 hours in my case.

I investigated my configuration again.
And I can't get any answers.
But I resolved this problem, so I write how to resolve this.

I rewrote flow tags to job tags.
Sample is below:
before:

<job id="jobFile"  ... >
    ....   
    <step id="step5" next="....">
      <flow id="flow1" />
    </step>
  </job>

  <flow id="flow1">
    <step id="flow1.step1" next="flow1.step2"/>
    <step id="flow1.step2"/>
  </flow>

after:

  <job id="jobFile"  ... >
    ....   
    <step id="step5" next="....">
      <job ref="job1.flow1" job-launcher="jobLauncher" 
          job-parameters-extractor="jobParametersExtractor"/>
    </step>
  </job>

  <job id="job1.flow1" restartable="true">
    <step id="flow1.step1" next="flow1.step2"/>
    <step id="flow1.step2" />
  </job>

I don't know the reason, but above modification makes SpringBatch work well.
The loading time become about 10sec!

Thank you for many comments!

That's slightly worrying, if still puzzling (because no-one else has the problem), but it's good that you have a workaround. I raised a JIRA ticket for you (https://jira.springsource.org/browse/BATCH-1782).
