30    * Use this Advice to map one exception to another for use when other
31    * advice eats your runtime exceptions outside of your code. This happens in
32    * Transactions when commit is not called until outside of your DAO
33    * layer.
34    * </p>
35    *
36    * <p>
37    * Set the property "exceptionMapping" as a map that maps an exception class to
38    * your own exception class
39    * </p>
40    *
41    * <p>
42    * Remember that aspect order is important and that this bean will always be
43    * order "500"
44    * </p>
45    *
46    * Example:
47    *
48    * <pre>
49    * &lt;tx:annotation-driven transaction-manager=&quot;JtaTxManager&quot; order=&quot;1000&quot;/&gt;
50    * lt;bean id=&quot;mapExceptionAdvisor&quot;
51    * class=&quot;org.myfoo.ExceptionMappingAdvice&quot;&gt;
52    * &lt;property name=&quot;exceptionMapping&quot;&gt;
53    * &lt;map&gt;
54    * &lt;entry key=&quot;javax.persistence.EntityExistsException&quot;
55    * value=&quot;org.myfoo.exceptions.AlreadyExistsException&quot; /&gt;
56    * &lt;/map&gt;
57    * &lt;/property&gt;
58    * lt;/bean&gt;
59    * lt;aop:config&gt;

63    * pointcut=&quot;execution(* org.myfoo.service.*.*(..))&quot;
