Advantage of Spring

Spring is a popular framework, ho开发者_JAVA技巧wever I have difficulties to see in which situation the framework would actually help.

Currently I'm using the following: * Tomcat * Jersey * Jackson * Hibernate

Together this results in a Webservice, created by annotations, automatic JSON (un)marshalling and a comfortable Object/Relational Mapping.

So honestly at the moment I'm not missing anything, but I might just not know what great thing I'm missing... Could you help me out with this? Thank you

Spring is a big framework providing a lot of functionality. It's hard to talk about advantages without knowing what functionality are you trying to use in the project.

Most probably you talk about Spring as an IoC container. It is very important part of Spring, but there is also AOP, transaction management, JDBC abstraction layer, authentication and authorization, testing and some more.

In a nutshell, Spring offers you uniform way to control dependencies between your objects. This is called inversion of control or dependency injection. Using it you can create pluggable, testable code that is easy to maintain.

In addition it gives you gazillion utility classes that just make life easier. For example, Hibernate is much easier to maintain via Spring facilities. It kind of brings together many different technologies under the same roof.
