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;
}
}
