Most common injection mechanisms used in Spring are Constructor and Property injections. In both the mechanisms, the injection happens only once during the initialization of the Bean. They also require a concrete method defined, e.g., a constructor method for constructor injections and a setter method for property injection.

Custom namespaces in spring are a way to replace the complex bean definitions with a more user-friendly configuration.
Spring itself provides several namespaces out of the box. e.g.

Localization with Spring
Localization enables applications to cater to users of different locations and languages. Spring, as usual, has support for this aspect as well.
Before jumping into what Spring has to offer, let's explore what we get from Java itself.

Spring Boot - How to Create a Deployable War
Spring boot, by default, enables you to create standalone applications through simple, minimal configurations. And due to its self-contained nature, it naturally enables building microservices.

Spring Cache - Part 5 - CacheEvict
In the Spring Cache series so far (Part1, Part2, Part3, Part4), we have seen examples where the data is getting added to the cache through the use of
@Cacheable and @CachePut. But, what about removing data from cache? Consider a call to delete the record from Service or DB, in which case, we would also want to delete that record from the cache.Deep Copy Java Objects through Serialization
When it comes to deep copy or cloning an object, the first thing that comes to mind is to override the
clone() method and set each field manually. This can be pretty cumbersome to implement for complex objects or if you have to do this for a lot of them.Spring Cache - Part 4 - CachePut
There are scenarios, unlike retrievals, where you do not want to skip the execution of the method e.g. insert/update of a record. Such methods should not be marked as Cacheable. But, you might still want to cache the result of these methods, in order to avoid unnecessary retrievals in future calls.
