title: Bulk insert using NamedParameterJdbcTemplate
body: <p>In my controller I am receiving one request which contains 2 parameters: one is an integer value another is a list.</p>
  
  <pre><code>{"store_id":12,"product":[[1,10],[2,20],[3,30]]}
  </code></pre>
  
  <p>And I want to insert like </p>
  
  <pre><code>12,1,10
  12,2,20
  12,3,30
  </code></pre>
  
  <p>I am using <code>NamedParameterJdbcTemplate</code> for db queries. I tried with batchquery but its time consuming. Is there any other way to do in better performance?</p>
