Jsp pass object to include

Question

I currently have a page with a little content that needs to be updated frequently.

For example: jsp content

Chapter 1 : section abc: section def: section ghi: 

Assuming I have a Chapter class and its sections are parameters in it

  class Chapter{ Section abc; Section def; Section ghi; } 

I am using spring mvc, adding the following models

 model.addAttribute("chapter", chapter); model.addAttribute("abc", chapter.getAbc()); model.addAttribute("def", chapter.getDef()); model.addAttribute("ghi", chapter.getGhi()); 

When the main page is called up, I can load individual sections using jsp: includes, and when I update them, I add this particular model to this particular jsp page myself and update it with ajax. It works great.

But

The question is, How can I change the design so that I can control the whole only with

 model.addAttribute("chapter", chapter); 

so that I can use the chapter object to get the values ​​abc, def, ghi, and not explicitly pass them.

The problem is that I cannot pass individual objects to jsps included from the chapter object, for example ..

 <jsp:include page="abc.jsp" > <jsp:param name="abc" value="${ chapter.abc}"/> </jsp:include> 

it's impossible. as i can only pass strings

minor problem, long description .. wishing I made my point.

Answer 1

You can pass strings only as query parameters, but you can set any type of objects as query attributes. The request area (not the page area) beans should also work.
