Spring 3 - What's the standard way of sending @RequestParam values back to the view?

StackOverflow https://stackoverflow.com/questions/6349694

题

I have a simple controller that handles a submit with a couple of parameters, not so much that I would consider creating a command object to store them.

In my controller I have annotated the parameters with @RequestParam but I have to send these values to the view and I don't know what's the best way of doing it.

If I had a command object I could use the modelAttribute on the html:form tag to bind the parameters but I don't want to create a command object for just a bunch of fields.

What is the preferred way of sending the values to the view (request attributes, model attributes ... )?

有帮助吗？

解决方案

I'd say model attributes. Something like

@RequestMapping("/path")
public void test(@RequestParam("q") String q, ModelMap model) {
    model.put("q", q);
}

On front end you could print it using your favourite approach. A sample with JSTL

<html> 
   ...
   <c:out value="${q}" />
 </html>
