Question

spring controller获取请求参数的方法用哪一种好

Answer 1

1、 通过@PathVariabl获取路径中的参数

@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";
}

2、 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";
}
