copied!<p>The <code>@ModelAttribute</code> method annotation is intended to be used for <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-modelattrib" rel="noreferrer">exposing reference data</a> to the view layer. I can't say for sure in your case, but I wouldn't say that a collection of users qualified as reference data. I suggest that you pass this information through to the model explicitly in your <code>@RequestMapping</code>-annotated handler methods.</p> <p>If you still want to use <code>@ModelAttribute</code>, there's a <a href="http://developingdeveloper.wordpress.com/2008/02/28/common-reference-data-in-spring-mvc/" rel="noreferrer">blog</a> entry here that discusses the redirect problem.</p> <blockquote> <p>But all the previous examples have a common issue, as all @ModelAttribute methods are run before the handler is executed, if the handler returns a redirect the model data will be added to the url as a query string. This should be avoided at all costs as it could expose some secrets on how you have put together your application.</p> </blockquote> <p>His suggested solution (see part 4 of the blog) is to use a <a href="http://static.springsource.org/spring/docs/3.0.x/reference/mvc.html#mvc-handlermapping-interceptor" rel="noreferrer"><code>HandlerInterceptorAdapter</code></a> to make the common reference data visible to the view. Since reference data shouldn't be tightly coupled to the controllers, this shouldn't pose a problem, design-wise. </p>
