![70][]

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

![70 1][]![70 2][]

3、点击finish完成，右键项目，部署spring开发

![70 3][]

取消勾选该页所有选择

![70 4][]

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

![70 5][]

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;
    	}
    }
