这个注释可以从请求中获得参数。

package roseindia.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.multipart.commons.CommonsMultipartFile;import roseindia.form.SampleForm;@Controller@RequestMapping(value = "/param/")public class ApplicationController {@RequestMapping(value = "/index")public String loadIndex(Model model, SampleForm sampleForm) {model.addAttribute("sampleForm", sampleForm);return "index";}/* * The method written below takes the request parameters individually by * using @RequestParam However you can also use @ModelAttribute to take the * form/model object. */@RequestMapping(value = "/process-form")public String processForm(@RequestParam(value = "rollNo") Integer rollNo,@RequestParam(value = "name") String name,@RequestParam(value = "address") String address,@RequestParam(value = "commonsMultipartFile") CommonsMultipartFile commonsMultipartFile,Model model) {model.addAttribute("rollNo", rollNo);model.addAttribute("name", name);model.addAttribute("address", address);model.addAttribute("multipartFile", commonsMultipartFile);return "view-data";}}
