What is your efficiency by deleting XML in Java projects?

Question

I just moved from stage 1 to stage 2 of the project. In this transition, we got rid of the whole XML configuration for spring and struts2, switching to a fully annotated mode.

All participants are amazed at the actual effect it has on the speed of development. There are several reasons for this:

• structured to think about what roles are needed to lead to a clear understanding that we need @StubRepository, @TestService and @NotTestService annotations to facilitate all the different models at runtime that our project uses (at runtime, unit test, integration test, selenium test)
• These annotations have replaced a large number of duplicate xml definitions.
• All dependencies are fully tracked in the idea.
• Simplify working with code as dependencies are clear

Some of these accomplishments could probably be realized by restructuring the xml, but that would not be a trivial task.

I honestly believe that this gave an approximately 10% increase in productivity for our project of 20,000 man-hours. It's almost hard for me to believe.

Anyone else share this experience? What do you get and how do you explain it?

Answer 1

Basically, this can be seen as a matter of configuration files and annotations.

If you are faced with a performance improvement when adding some data in the form of annotations, this means that they were not “configuration” material in the first place.

The difference between the two:

Answer 3

I do not have such performance indicators as you, but I saw a significant improvement in the transition from xml configurations to annotations. I think this is because the configuration information is in the same place with the code.

Before you had to search for a separate file to find configurations and slow down.
