@RequestMapping(value = "/{id}/{str}") public ModelAndView helloWorld(@PathVariable String id, @PathVariable String str) { System.out.println(id); System.out.println(str); return new ModelAndView("/helloWorld"); }
用@ModelAttribute注解获取POST请求的FORM表单数据
<form method="post" action="hao.do" enctype="multipart/form-data"> a: <input id="a" type="text" name="a" value="a"/> b: <input id="b" type="text" name="b" value="10"/> file0: <input id="file0" name="addFiles" type="file" /> file1: <input id="file1" name="addFiles" type="file" /> <input type="submit" value="Submit" /> </form>
public class Pojo{ private String a; private int b; private List<MultipartFile> addFiles = new ArrayList<MultipartFile>(); ...set();get();... }
@RequestMapping(params = "method=processSubmit") public String processSubmit(@ModelAttribute("pojo") Pojo pojo) { return "helloWorld"; }
直接用HttpServletRequest获取
@RequestMapping(method = RequestMethod.GET) public String get(HttpServletRequest request, HttpServletResponse response) { System.out.println(request.getParameter("a")); return "helloWorld"; }
用注解@RequestParam绑定请求参数a到变量a
当请求参数a不存在时会有异常发生,可以通过设置属性required=false解决,
例如: @RequestParam(value="a", required=false)
@RequestMapping(value = "/requestParam", method = RequestMethod.GET) public String setupForm(@RequestParam("a") String a, ModelMap model) { System.out.println(a); return "helloWorld"; }
