Caching with ehcache-spring-annotations API

This blog contains a simple example of spring ehcache. This cache is use to save static data in form of Object. This example has two components, service and model; here service contains basic curd operations, along with a cache operation.

Project Structure
spring-ehcach src\main\java com.wiki.dto AccountDTO AccountListDTO com.wiki.service AccountDataService com.wiki.service.impl AccountDataServiceImpl src\main\resources account-ehcache.xml spring-ehcache-context.xml src\test\java com.wiki AllTests com.wiki.service AccountDataServiceTest src\test\resources spring-ehcache-test-context.xml
Main Package
AccountDTO	Account DTO with basic account information like accountId, accountHolderName, accountEmail, accountContactNo, accountDOB, currency
AccountListDTO	List of Account DTO
AccountDataService	Interface of AccountDataService
AccountDataServiceImpl	Actual implantation of AccountDataService with curd oprations
account-ehcache.xml	Ehcache operations descriptor File
spring-ehcache-context.xml	Spring context descriptor File
Test Package
AllTests	All Test Cases Starting Point.
AccountDataServiceTest	Account Data Service Test Case
spring-ehcache-test-context.xml	Spring context descriptor File for test package.

1. Create a maven project spring-ehcache
2. Add below mention required dependencies in pom.(Pom.xml)
3. Prepare AccountDTO, and AccountListDTO.
4. Prepare an Interface for Service (AccountDataService).
5. Implements of service interface (AccountDataServiceImpl). Prepare cached method cached account Data
6. Prepare spring wiring for service classes and configure cache manager with service.
7. Configure accountDataService bean an
8. Configure cache Manager and refresh interval time, and cache configuration file.

Please build your project. To test your AccountDataService, we have AccountDataServiceTest. Through this we can check caching debug in dubug mode.
Request 1
[AccountDataServiceTest] => [AccountDataService] => [AccountDataServiceImpl] => [EhcacheInterCepter] => [CachedAccountData]

Request 2
[AccountDataServiceTest] => [AccountDataService] => [EhcacheInterCepter] => [CachedAccountData]
First request call actual service to retrieve data from AccountDataService and store it to cached via EhcacheInterCepter.

Second request call EhcacheInterCepter to retrieve cached data from EhcacheInterCepter. Actual AccountDataService will call after given interval.
