Use EhCache to configure the Hibernate secondary cache:

Configure Hibernatee secondary cache preparation:

1) add ehcache-1.2.3.jar to the classpath of the current application.

2) add the providing class of the EhCache cache plug-in to the hibernate.cfg.xml file.

Org.hibernate.cache.EhCacheProvider

3) send the ehcache.xml file to the classpath (under the src directory of the project), and this file is in the etc of the Hibernate installation directory.

/ / configure cache. Read-write concurrent access strategy must be adopted for Category objects in the cache immediately after the class element.

Hibernate secondary cache hosted by Spring

1. In the configuration file of spring, add the xml code org.hibernate.cache.EhCacheProvider true in the hibernate section

two。 Set the cache policy xml code for the HBM table

3. In DAO, set to use the cached Java code getHibernateTemplate (). SetCacheQueries (true) before calling the find method query

Add: if you do not set the query cache, Hibernate will only cache a single persistent object obtained using the load () method. If you want to cache the data result set obtained using the findall (), list (), Iterator (), createCriteria (), createQuery () methods, you need to set hibernate.cache.use_query_cache true.
