Implementing spring caching with ehcache....

Implementing spring caching with ehcache....

The Spring caching is in the spring-context.jar, to 

 support Ehcache caching, you need to include the 

 spring-context-support.jar as well.

Step-1

Add Below Dependency for Ehcache.

<dependency>

   <groupId>net.sf.ehcache</groupId>

    <artifactId>ehcache</artifactId>

     <version>2.9.0</version>

</dependency>

<!-- Spring caching framework inside this -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

<version>4.1.4.RELEASE</version>

</dependency>

<!-- Support for Ehcache and others -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context-support</artifactId>

<version>4.1.4.RELEASE</version>

</dependency>

Step-2

 create a xml file as shown in below.

 ehcache.xml (classpath in this example)

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="ehcache.xsd" 

updateCheck="true"

monitoring="autodetect" 

dynamicConfig="true">

<diskStore path="java.io.tmpdir" />

<cache name="movieFindCache" 

maxEntriesLocalHeap="10000"

maxEntriesLocalDisk="1000" 

eternal="false" 

diskSpoolBufferSizeMB="20"

timeToIdleSeconds="300" timeToLiveSeconds="600"

memoryStoreEvictionPolicy="LFU" 

transactionalMode="off">

<persistence strategy="localTempSwap" />

</cache>

</ehcache>

Step-3

<!-- Define the cache manager factory instance -->

   <bean id="ehcache"

     class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"

                p:configLocation="classpath:ehcache.xml" p:shared="true" />

Step-4

<!-- Define the cache manager instance -->

        <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"

                p:cacheManager-ref="ehcache" />

Step-5

<!-- Drive caching via annotations -->

        <cache:annotation-driven cache-manager="cacheManager"

                proxy-target-class="true" />

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);

     }

Developing Soap web service using Spring-WS framework (top down approach)

Developing web services(Spring-WS) that start with the XML Schema/WSDL contract first followed by the Java code second. Spring-WS focuses on this development style.

The most important thing when doing contract-first Web service development is to try and think in terms of XML. This means that Java-language concepts are of lesser importance. It is the XML that is sent across the wire, and you should focus on that. The fact that Java is used to implement the Web service is an implementation detail.
