Spring MVC: Binding Complex Objects as GET @RequestParam
Problem:
Consider a scenario where you have a page listing objects from a table. You need to add a form to filter the table using Ajax GET requests sent to a URL similar to:
http://foo.com/system/controller/action?page=1&prop1=x&prop2=y&prop3=z
Instead of using numerous @RequestParam parameters on the controller method, you'd like to bind the entire filter object directly.
Example:
Assuming you have a MyObject class defined as:
public class MyObject { private String prop1; private String prop2; private String prop3; // Getters and setters // ... }
Your ideal controller method would look like this:
@RequestMapping(value = "/action") public @ResponseBody List<myobject> myAction( @RequestParam(value = "page", required = false) int page, MyObject myObject)</myobject>
Solution:
Spring provides the capability to bind complex objects as @RequestParam parameters. To achieve this, simply remove the @RequestParam annotation from your method argument:
@RequestMapping(value = "/action") public @ResponseBody List<myobject> myAction( @RequestParam(value = "page", required = false) int page, MyObject myObject)</myobject>
Spring will automatically bind the request parameters to your MyObject instance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
