值的传递分为从页面传到到controller和从controller传递到页面,下面分别进行介绍:

package com.springmvc.web;

import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class HelloController {
    
    @RequestMapping("test")
    public String test(@RequestParam("username")String username,Map<String, Object> map){
        map.put("username", username);
        return "test";
    }
    
    @RequestMapping({"/hello","/"})
    public String hello(String username,Map<String,Object> map){
        System.out.println("username==" + username);
        map.put("username", username);
        map.put("password", "222");
        return "hello";
    }
    
    @RequestMapping("/welcome")
    public String welcome(String username,Model model){
        System.err.println("username=" + username);
        model.addAttribute("username", username);
        model.addAttribute("password", "333333333");
        model.addAttribute(username);
        return "welcome";
    }
}
