If I want to build a website which provide services to help others dynamically generate website online, any solutions on that?

plus: I am using java and familiar with spring framework.

some thoughts on this:

1. UI templates for user to select.


2. common components like search function and db crud generation automatically


3. when the website is done, can help user to deploy it online automatically

Are there any solutions and suggestions on such a project?

Hope for your help.

Thanks.
