@RequestMapping(value="user/{id}/{name}",method=RequestMethod.GET)
public String printMessage1(@PathVariable String id,@PathVariable String name, ModelMap model) {
System.out.println(id);
System.out.println(name);
model.addAttribute("message", "111111");
return "users";
}
例如，访问user/123/lei路径时，执行以上方法，其中，参数id=123，name=lei
JSP表单如下
<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>
Java Pojo如下
public class Pojo{ private String a; private int b; }
Java Controller如下
@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"; }
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)
Controller如下
@RequestMapping(value = "/requestParam", method = RequestMethod.GET) public String setupForm(@RequestParam("a") String a, ModelMap model) { System.out.println(a); return "helloWorld"; }
