Cache Handling – CacheAspect Aspects Defined in AHServiceContext.xml Spring Advice Types Before advice: Executes before a method enters execution. After returning advice: Executed after a method completes normally. After throwing advice: Executed if a method exits by throwing an exception. After (finally) advice: Executed regardless of the means by which a method exits. Around advice: Perform custom behavior before and after the method invocation. Objective When reading data, use cache instead of database When writing data, update cache as necessary

AHService Config Files Overview

Utility Classes UIDGenerator – A 24 character-length unique string generator, based on System.currentTimeMillis(), host IP address, and java.security.SecureRandom(“SHA1PRN”). It’s used by AHEventPublished to assign event id. Also used by AhJmsTopicMsgPublisher to set service call id. AHSizeAgent – Make rough calculation of memory consumption size for those stored in cache. Was used by AHCacheAspect getAccountsFromCache(), getAccountHierarchyByID(). Not in use right now. AHContextListener – Registered in web.xml as a listener class. Upon context initilization being finished, it calls AHStartupLoader to load data from database into cach. It also pass the ESF config file to ESFXMLConfigurationBuilder to initilize the ESF framework components. AHDefaultConnectorExceptionStrategy – An extension class to org.mule.impl.DefaultExceptionStrategy, in its defaultHandler(Throwable t) method, it simply output the error message via Log4J, its declared as the exception strategy for JMS connection in esf_config_deploy.xml AHEventPublisher – It’s frequently used AHCacheAspect during most cache data change situations. The method publish(Serializable) convert a cached object (e.g. PfClientAcct) into AHEvent object. The AHEvent object is then dispatched through ESFClient to “vm://ahJmsProxy”. A BridgeComponent declared in esf_config_deploy.xml then resend it to citi.eqpb.ny.pbapps.gpf_ Equity.AHNotificationReceiver via Axis JMS channel

The Others Performance Most functions running 2-3 times longer than typical hibernate implementation If service guanrentees that data consistency between Gemfire cache and database why should we get the data from service? Function Flexibility What if we only want part of the result object? What if we need complex searching logic? Data Integrity Does the service always know what’s been changed? Are the interfaces thread safe? Maintain Effort Why so many files need to be changed when we only want to add a single attribute to vo object? Be able to run it in local, for easier coding and debug.
