A simple implementation of spring MVC + MyBatis's Ehcache

As a result of these two days the SPRINGMVC and MyBatis built web framework is then ready to be cached data, simply record the

Get ready:

Googlecode's Ehcache

This can be downloaded in the https://code.google.com/p/ehcache-spring-annotations/, downloaded after the use of the jar package

　　　　

Note Pack Ehcache-spring-annotations-1.2.0.jar in the downloaded Compression pack  

Since some of the other packages are already in spring MVC, you just need to add these in.

Configure Ehcache.xml

The new configuration ehcache.xml in the SRC directory is as follows:

<?XML version= "1.0" encoding= "UTF-8"?><!--/** * * Cache configuration * @author YQ * @date 2014.9.10 * */ - <EhcacheXmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:nonamespaceschemalocation= "Http://ehcache.org/ehcache.xsd"UpdateCheck= "false">   <DiskstorePath= "Java.io.tmpdir" />   <DefaultcacheEternal= "false"maxelementsinmemory= "+"Overflowtodisk= "false"diskpersistent= "false"Timetoidleseconds= "0"Timetoliveseconds= "All"Memorystoreevictionpolicy= "LRU" />     <Cachename= "Customercache"Eternal= "false"maxelementsinmemory= "+"Overflowtodisk= "false"diskpersistent= "false"Timetoidleseconds= "0"Timetoliveseconds= "+"Memorystoreevictionpolicy= "LRU" />    </Ehcache>  

You can have multiple caches in this configuration to easily manage the cache in our program.

Configure Spring.xml

1  <Ehcache:annotation-drivenCache-manager= "Ehcachemanager" />   2  <BeanID= "Ehcachemanager"class= "Org.springframework.cache.ehcache.EhCacheManagerFactoryBean">    3        < Propertyname= "Configlocation"value= "Classpath:ehcache.xml" />    4    </Bean>  

The next step is to try out the cache on our code Service tier:

@Cacheable (CacheName ="Customercache")     PublicCustomer Getcustomerbycid (intCID) {System. out. Print ("----------------------------------------------------------"); returnCD.    Getcustomerbycid (CID); }    //Modify Customer@TriggersRemove (CacheName ={"Customercache"},removeall=true)     Public intUpdateCustomer (Customer cus) {returnCD.    UpdateCustomer (cus); }

Note that the import of the package is the two

Import com.googlecode.ehcache.annotations.Cacheable; import Com.googlecode.ehcache.annotations.TriggersRemove;

The above is already built.

When we call the Getcustomerbycid method in the service two times, the console has only one SQL print to indicate success.
