1.pojo

package pojo;
public class Product {

    private int id;
    private String name;
    private float price;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public float getPrice() {
        return price;
    }
    public void setPrice(float price) {
        this.price = price;
    }

}

2.input.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" import="java.util.*" isELIgnored="false"%>

<form action="addProduct">

    产品名称 ：<input type="text" name="name" value=""><br />
    产品价格： <input type="text" name="price" value=""><br />

    <input type="submit" value="提交">
</form>

3.Controller

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import pojo.Product;

@Controller
public class ProductController {

    @RequestMapping("/addProduct")
    public ModelAndView add(Product product) throws Exception{
        ModelAndView mv = new ModelAndView("show");
        return mv;
    }
}
