Custom data exception with Spring + hibernate

Today a colleague of mine (Poli) came asking for a way to convert error codes produced in stored procedures in an Oracle legacy database. The project was using hibernate and spring.

Out first reaction was to dig into hibernate and look for mechanisms to intercept exception but unfortunately neither hibernate interceptors or the new event system has support for a onException or onError pointcut. We quickly turned to spring and realized this was actually a better idea since spring already does it own convention of multiple exceptions into its coherent exception hierarchy.

What we ended up doing was this:
1) Create your own exception. Lets call it MyCustomException (what and original name)

2) Copy sql-error-codes.xml from Spring source to your classpath.

3) Modify the copied sql-error-codes.xml and add your own entry in the database dialect you are using (MS-SQL, Oracle, etc). We added the 20999 code to Oracle so our bean definition looked something like this:



<bean id="Oracle" class="org.springframework.jdbc.support.SQLErrorCodes">
<property name="badSqlGrammarCodes"><value>900,903,904,917,936,942,17006</value></property>
<property name="dataIntegrityViolationCodes"><value>1400,1722,2291</value></property>
<property name="cannotAcquireLockCodes"><value>54</value></property>
<property name="customTranslations">
<list>
<bean class="org.springframework.jdbc.support.CustomSQLErrorCodesTranslation">
<property name="errorCodes"><value>20999</value></property>
<property name="exceptionClass"><value>MyCustom</value></property>
</bean>
</list>
</property>
</bean>


Note the use of CustomSQLErrorCodesTranslation to set a special bean we will look at later. Later you input the errorCodes that you should trap and the exception it should throw. What puzzeles is why I need to copy the entire sql-error-codes.xml. Maybe someone can check if this actually is needed or not.

4) In you hibernate respository or DAO make:
a) If you make use of Spring hibernateTempalate and callback Spring will automatically wrap you exceptions. It will look something like this (in this case I’m not inheriting from HibernateDAOSupport from Spring that should make this could simpler)


public Collection loadProductsByCategory(final String category) throws DataAccessException {
HibernateTemplate ht = new HibernateTemplate(this.sessionFactory);
return (Collection) ht.execute(new HibernateCallback() {
public Object doInHibernate(Session session) throws HibernateException {
Query query = session.createQuery("from test.Product product where product.category=?");
query.setString(0, category);
return query.list();
}
});
}


b) If you don’t use callback you’ll have to tell Spring to do the exception convertion explicitly like:



public Collection loadProductsByCategory(String category) throws DataAccessException, MyException {

Session session = getSession(getSessionFactory(), false);
try {
List result = session.find("from test.Product product where product.category=?",category, Hibernate.STRING);
if (result == null) {
throw new MyException("invalid search result");
}
return result;
} catch (HibernateException ex) {
throw SessionFactoryUtils.convertHibernateAccessException(ex);
}
}


As you can see, there is a call to convertHibernateAccessException that converts the hibernate exception to the defined Spring hierarchy.

Now you can have typed exceptions thrown from your repositories instead of nasty generic Hibernate or JDBC exceptions. Have fun!
