试用Hibernate二级缓存Ehcache

? Hibernatesupports several third-party caching services.?After some research, the team has concluded that Ehcache would besuitable for our requirements, namely the caching of frequently-accessed,read-only tables.

Ehcache Evaluation

Hibernate 3.3.2 GA

Ehcache 1.2.3 (an optional JAR bundled with Hibernate 3.3.2)

Hibernate Annotations 3.4.0 GA

Configuration

Hibernate is configured to enable caching.

An ehcache.xml file is created and placed on the classpath.

Model classes are updated to add @Cache annotations to entities and associations.

Hibernate Query instances are explicitly designated as cacheable before execution.

?3,model example,Questionnaire.java

?4,Query cache,??? Old:Depth Optimization??? Old:private List<Response> findRespose(Long pageInQuestionId, Set aSetResponses,String responseValue) {List<Response> lResponses = new ArrayList();Iterator listResponses = aSetResponses.iterator();while (listResponses.hasNext()) {Response lResponse = (Response) listResponses.next();if (lResponse.getQuestion().getId() == pageInQuestionId && lResponse.getValue().equals(responseValue)){lResponses.add(lResponse);} } // Response could not be found:return lResponses;}
??If any question I will put in this thread.
