Service Layer Using Spring

  • Spring framework supports and promotes the loose coupling in the code because of which code can be updated and maintained easily.
  • Spring framework comes with prebuild features which make the life of java and programmer easy.
  • Testing an application written in the Spring framework is easy because of the support and library provided by the spring framework. Let us understand it better as the spring framework can easily interact and can work well with test frameworks such as Junit, Mockito, and so on. As a result, unit integration testing becomes easy with the spring framework.
  • Spring framework is light and easy to use and removes most of the code implementation.
  • Spring framework can be used both for developing desktop applications as well as web-based sites.
  • In tightly coupled, the data or objects are hardcoded in the code because of which we can face many problems such as if we want to update the data then we have to update it at all the positions where it is been used in the code, keeping track of it and maintaining is troublesome.
  • In loosely coupled the data and objects are not hardcoded in the system because of which updating, changing stuff is much easier.
