SpringMVC参数传递方式

1、通过@RequestParam注解 例：

<span style="white-space:pre"></span>@RequestMapping(value = "/update")public String update(@RequestParam(value = "age", required = false, defaultValue = "0") int age, RedirectAttributesModelMap model,HttpSession httpSession) {return "redirect:list/"+1 ;}

2、通过@PathVariable注解 例： 

<span style="white-space:pre"></span>@RequestMapping(value = "/delete/{id}")public String delete(@PathVariable("id") int id,RedirectAttributesModelMap model,HttpSession httpSession) {   <span style="white-space:pre"></span>model.addFlashAttribute(Constant.MESSAGE, " 操作成功。");return "redirect:../list/" + 1;}

需要注意的是的这里的重定向写法，这两个重定向都是去找了“/list/{pageNum}”方法，

1里面是 redirect:list/

2里面是 <span style="font-family:KaiTi_GB2312;">redirect:../list/ </span>
