and use it with
<bean id="positionVacancyDAO" parent="cacheProxyTemplate">
<property name="cachingModels">
<props>
<prop key="findCompanies">refreshPeriod=300</prop>
</props>
</property>
<property name="target">
<ref local="positionVacancyDAOTarget" />
</property>
</bean>
where the "positionVacancyDAOTarget" is you dao does the query to the
database
"findCompanies" is function call you want to cache the result
and "refreshPeriod=300" means first call goes to the db, and for every call
within 5 minutes (300 seconds), just use the cache.
i think ideally there is a transaction-proxied service that uses your
cache-proxied dao and your jsf code calls the service.
i've asked the spring people about this, and they hinted that using
hibernate and a secondary cache is better..
