title: Spring-JDBC batchUpdate is not committing changes. Is this a knwon bug?
body: <p>The project I am working on uses following dependency</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.springframework&lt;/groupId&gt;
      &lt;artifactId&gt;spring-jdbc&lt;/artifactId&gt;
      &lt;version&gt;3.2.0.RELEASE&lt;/version&gt;
   &lt;/dependency&gt;
  </code></pre>
  
  <p>With this I am making following <b>method call (1)</b></p>
  
  <pre><code>template.batchUpdate(INSERT_SQL, instance of BatchPreparedStatementSetter);
  </code></pre>
  
  <p>Looking at the source code in Spring JDBCTemplate it seems that (since the driver supports
  batch update) <b>executeBatch()</b> on <b>PreparedStatement</b> is called. I do not however see the effects of update in the database.</p>
  
  <p>Is this a genuine bug or am I missing the obvious here? If this has been resolved please advise of a good version. <b>Please note</b> that I need a version that has no dependency on other Spring modules such as Spring Core or MVC. Thanks in advance. </p>
