title: How to get JSON value from JDBC template
body: <p>I have a DB Table <code>order</code> where columns are</p>
  <pre><code>{
    order_id Long PRI,
    order_cost Long,
    String address,
    item_names json
  }
  </code></pre>
  <p><code>item_names</code> contains <code>List&lt;String&gt;</code></p>
  <p><code>item_names</code> will be like: <code>[&quot;Books&quot;, &quot;Pens&quot;, &quot;papers&quot;, &quot;Pencils&quot;, &quot;Erasers&quot;]</code></p>
  <p>I want to get value of <code>item_names</code> using <code>JdbcTemplate</code>.</p>
  <p>For <code>order_cost</code> I call <code>jdbc_template.queryForObject(query_str, Long.class);</code>
  where <code>query_str</code> is <code>&quot;SELECT order_cost FROM order WHERE order_id = &quot; + ordrId;</code></p>
  <p>But how do I get <code>item_names</code> which is of type <code>json</code>?</p>
