The service locator design pattern is used when we want to use JNDI lookup and use business component such an EJB beans and JMS component and services such as datasources. Considering high cost of looking up JNDI for a service, Service Locator pattern makes use of caching technique. For the first time Service locator lookup in JNDI and cache it. Further lookup on the same service via Service Locator is done in its cache which improves performance.
If you using a DI container like Spring then you don’t need to implement service locator pattern. If you are using any JNDI lookup then it is better to use service locator pattern.
