Spring MVC Annotation @RequestParam example
Annotation which indicates that a method parameter should be bound to a web request parameter.
Supported for annotated handler methods in Servlet and Portlet environments.
If the method parameter type is Map and a request parameter name is specified, then the request parameter value is converted to a Map assuming an appropriate conversion strategy is available.
Example
package com.candidjava.springmvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class CustomerController
{
@RequestMapping(value = "/customer.htm")
public ModelAndView addCustomer(@RequestParam("txt_username") String txt_username, @RequestParam("txt_password") String txt_password)
{
ModelAndView model = new ModelAndView("page");
model.addObject("msg", "RequestMapping for URL Parameters username = " + txt_username + " and password = " + txt_password);
return model;
}
