SpringMVC Form表单

学习参考自易百教程

1、新建javaWeb工程springMVC_Form,选择Web服务器

2、点击next，取消生成index.jsp,勾选web.xml,取消导入jstl库

3、点击finish完成，右键项目，部署spring开发

取消勾选该页所有选择

4、点击finish完成。接下来编写student类和controller控制器添加dispatcher-servlet.xml，完成web.xml和新建jsp文件，目录如下

FormController：

package com.controller;

import com.model.*;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class FormController {

	@RequestMapping(value="/student",method=RequestMethod.GET)
	public ModelAndView Student(){
		return new ModelAndView("student","command",new Student());
	}
	
	@RequestMapping(value="/addStudent",method=RequestMethod.POST)
	public String addStudent(@ModelAttribute("SpringWeb")Student student,Model model){
		model.addAttribute("sno",student.getSno());
		model.addAttribute("sname",student.getSname());
		model.addAttribute("gender", student.getGender());
		model.addAttribute("score",student.getScore());
		return "result";
	}
}

Student类：

package com.model;

public class Student {
	private String sno;
	private String sname;
	private String gender;
	private double score;
	public String getSno() {
		return sno;
	}
	public void setSno(String sno) {
		this.sno = sno;
	}
	public String getSname() {
		return sname;
	}
	public void setSname(String sname) {
		this.sname = sname;
	}
	public String getGender() {
		return gender;
	}
	public void setGender(String gender) {
		this.gender = gender;
	}
	public double getScore() {
		return score;
	}
	public void setScore(double score) {
		this.score = score;
	}
}
