Since Spring 2.5, annotation-based configuration has been an alternative to XML setups. Annotation based configuration rely on the bytecode metadata for wiring up components instead of angle-bracket declarations. Annotations can be used on the relevant class, method, or field declaration. Annotation injection is performed before XML injection, thus the latter configuration will override the former [...]

In the previous post Custom Spring Callback Methods I discussed about the customizing bean lifecycle callback methods which are required at the time of bean initialization and its destruction. In this post I shall cover another aspect of Spring Container Extension Points. Note:Extension Points are well defined exposed places/hooks for others to provide extended functionality. [...]

Hibernate One-To-Many Mapping Example Using Annotations
In this tutorial we will write a simple Java project to demonstrate Hibernate one to Many Mapping using Java Annotations. In my previous article I have explained Hibernate one to Many Mapping using XML. The main difference between these two examples would be the hibernate configuration files and annotations. Otherwise both the articles trying the same [...]
