SpringMVC传参
- - 企业架构 - ITeye博客Spring MVC 的请求参数获取的几种方法. 通过@PathVariabl注解获取路径中传递参数. 用@ModelAttribute注解获取POST请求的FORM表单数据. 直接用HttpServletRequest获取. 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,.
@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"); }
<form method="post" action="hao.do"> a: <input id="a" type="text" name="a"/> b: <input id="b" type="text" name="b"/> <input type="submit" value="Submit" /> </form>
public class Pojo{ private String a; private int b; }
@RequestMapping(method = RequestMethod.POST) public String processSubmit(@ModelAttribute("pojo") Pojo pojo) { return "helloWorld"; }
@RequestMapping(method = RequestMethod.GET) public String get(HttpServletRequest request, HttpServletResponse response) { System.out.println(request.getParameter("a")); return "helloWorld"; }
@RequestMapping(value = "/requestParam", method = RequestMethod.GET) public String setupForm(@RequestParam("a") String a, ModelMap model) { System.out.println(a); return "helloWorld";}
