UsingPHPasaSpringMVCViewviaQuercus(转)_PHP教程

http://blog.caucho.com/2009/04/14/using-php-as-a-spring-mvc-view-via-quercus/

This week, I’ve been prepping for a talk on Quercus in which I promised to show a demo of Spring MVC using a PHP view. So that means that I actually had to do it. Turns out it was quite easy and PHP makes for a very nice, compact view technology for Spring MVC. This is a bit of tease since the code for this won’t go out until at least next week, but since a number of people have been asking for this a while, I thought I’d give a preview…

First, let me show how it looks by using the sample “ImageDB” application that ships with Spring. Here’s a screenshot of the app in action:

Basically, you upload an image to the page and it keeps track of what you’ve uploaded in a database. Here are the JSP and PHP views side-by-side:

< table border=https://www.gxlcms.com/"1" cellspacing=https://www.gxlcms.com/"0" cellpadding=https://www.gxlcms.com/"5"> < form action=https://www.gxlcms.com/"imageUpload" method=https://www.gxlcms.com/"post" encType=https://www.gxlcms.com/"multipart/form-data">

What I think is interesting between these two is that the PHP, even though it’s calling Java objects, has a simpler syntax. It’s not a major issue, but you can see that PHP is as reasonable as any other view for Java.

Now how do you configure it? Just add the QuercusView class to a UrlBasedViewResolver and give a php suffix and you’re done:

If you’re interested in the implementation… The view was pretty easy to connect up once I learned Spring’s view API. It’s essentially a Servlet.service() call with a map of model values. So the QuercusView class above is just a modified QuercusServlet that injects the model values as PHP globals. I’m not sure that that’s right just yet, but it’s a start. The other option would be to put the values as PHP superglobals or in a specialized Spring array.
