title: Accessing jobParameter on ItemProcessor on Spring batch
body: <p>I'm new to spring batch and during my development I came across a scenario where I need to access a jobParameter on an ItemProcessor. I've done this on a reader (MultiresourceReader and StaxeventItemReader also with a CustomReader that I have built) and it was successful, I can retrieve jobParameter but not with ItemProcessor.</p>
  
  <p>Here is my snippet.</p>
  
  <pre><code>&lt;bean id="myProcessor" class="com.......MyCustomProcessor" scope="step"&gt;
      &lt;property name="myBean" ref="customBean"/&gt;
  &lt;/bean&gt;
  &lt;bean id="customBean" class="...................MyCustomBean" scope="step"&gt;
      &lt;property name="file" value="#{jobParameters['FILE']}/fileName.txt"/&gt;
  &lt;/bean&gt;
  </code></pre>
  
  <p>It is producing a lazyBinding Exception. Any idea on how to retrieve the jobParameter on an item Processor?</p>
