   <p>The most important thing you must ensure is that you close any sessions that you open. The best way to ensure this is to use the following unit of work pattern:</p>
   <source>SqlSession session = sqlSessionFactory.openSession();
 try {
-    // following 3 lines pseudocod for "doing some work"
+    // following 3 lines pseudocode for "doing some work"
     session.insert(...);
     session.update(...);
     session.delete(...);
     session.commit();
 } finally {
     session.close();
+}</source>
+  <p>Or, If you are using jdk 1.7+ and MyBatis 3.2+, you can use the try-with-resources statement:</p>
+  <source>
+try (SqlSession session = sqlSessionFactory.openSession()) {
+    // following 3 lines pseudocode for "doing some work"
+    session.insert(...);
+    session.update(...);
+    session.delete(...);
+    session.commit();
 }</source>
   <p><span class="label important">NOTE</span> Just like SqlSessionFactory, you can get the instance of Configuration that the SqlSession is using by calling the getConfiguration() method.</p>
   <source>Configuration getConfiguration()</source>
