how does Spring Roo help incorporate best practices

[Paul Anilprem]

Hi Ashish,
I read your blog post titled "Spring Roo - future of Java application development". There, you've mentioned 3 examples of where Spring Roo comes into picture. I am thinking all these 3 things are easily handled by the IDEs. Do you think what is generated by IDEs does not follow best practices? How is what generated by SR is better than that? Could you please explain that?

Could you please give any concrete example where SR adds a value not provided by IDEs?

thank you,
Paul.

Hi Paul,

Spring Roo is a code generation tool. The examples that I talked about in my blog refer to some of the auto-generated code by Spring Roo, which you can do using an IDE also. The best practices are related to how the code is structured and how Spring framework features are used. For instance, in an application the interaction between layers is Web --> Service --> DAO. If you are developing a Spring-based application, a good practice is to create different application contexts XML files for objects in the web layer and the dao+service layer. If you are using Spring Roo, then this is automatically done for you. Another example is - Spring Roo scaffolded web layer is RESTful in nature.
