Implementing Spring caching in project @ Service Layer

Implementing Spring caching in project

STEP-1

Enabling Spring caching annotation:-

Define spring cache manager and enable the cache annotation in meta-configuration file

<cache:annotation-driven cache-manager="cacheManager" proxy-target-class="false"/>

STEP-2

Defining Spring cache manager..

<!-- generic cache manager -->

<bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">

<property name="caches">

           <set>

  <bean class="org.springframework.cache.concurrent.
ConcurrentMapCacheFactoryBean" p:name="spring-mvcCache"/>

           </set>

</property>

</bean>

Note : Cache name is spring-mvcCache

STEP-3

Applying annotation on service layer...................

    @Cacheable(value="quote", key="#quoteNumber")

     public Quote getQuote(String quoteNumber) {

           Quote retrievedQuote = new Quote(quoteNumber);

           try {

            retrievedQuote = quoteRetrieveSAO.retrieve(quoteNumber);

          } catch (RetrieveException e) {

    log.fatal("Failed to retrieve quote from cache for quote number:" + quoteNumber, e);

           }

           return retrievedQuote;

     }

     @CachePut(value="quote", key="#quoteNumber")

     public Quote updateQuote(String quoteNumber, Quote quote) {

           return quote;

     }

     @Cacheable(value="quoteErrors", key="#quoteNumber")

     public List<CollectionSetError> getQuoteErrors(String quoteNumber) {

           return new ArrayList<CollectionSetError>();

     }

     @Override

     @CacheEvict(value="spring-mvcCache",allEntries=true)

     public void deleteAlbum(int albumId) {

           String sql = "delete from albums WHERE albumid = " + albumId + " ";

           getJdbcTemplate().update(sql);

     }
