详解SpringMVC——接收请求参数和页面传参

@RequestMapping("/login.do") 
public String login(HttpServletRequest request){ 
  String name = request.getParameter("name") 
  String pass = request.getParameter("pass") 
} 

@RequestMapping("/login.do") 
public String login(HttpServletRequest request, 
                String name, 
 @RequestParam("pass")String password) // 表单属性是pass,用变量password接收 
{ 
  syso(name); 
  syso(password) 
} 

<form action="login.do"> 
用户名：<input name="name"/> 
密码：<input name="pass"/> 
<input type="submit" value="登陆"> 
</form> 
 
//封装的User类 
public class User{ 
 private String name; 
 private String pass; 
} 

 @RequestMapping("/login.do") 
public String login(User user) 
{ 
  syso(user.getName()); 
  syso(user.getPass()); 
} 

@RequestMapping("/login.do") 
public ModelAndView login(String name,String pass){ 
  User user = userService.login(name,pwd); 
  Map<String,Object> data = new HashMap<String,Object>(); 
  data.put("user",user); 
  return new ModelAndView("success",data); 
} 

@RequestMapping("/login.do") 
public　String login(String name,String pass ,ModelMap model){ 
  User user = userService.login(name,pwd); 
  model.addAttribute("user",user); 
  model.put("name",name); 
  return "success"; 
} 

@RequestMapping("/login.do") 
public String login(@ModelAttribute("user") User user){ 
  //TODO 
  return "success"; 
} 
 
@ModelAttribute("name") 
public String getName(){ 
  return name; 
} 

@RequestMapping("/login.do") 
public String login(String name,String pwd 
              ModelMap model,HttpServletRequest request){ 
   User user = serService.login(name,pwd); 
   HttpSession session = request.getSession(); 
   session.setAttribute("user",user); 
   model.addAttribute("user",user); 
   return "success"; 
} 

public ModelAndView login(){ 
  RedirectView view = new RedirectView("regirst.do"); 
  return new ModelAndView(view); 
} 

public String login(){ 
  //TODO 
  return "redirect:regirst.do"; 
}
