首先打開IDEA，File—>New—>Project創建項目

選擇左側導航欄里的Maven，勾上勾，選擇webapp

按如下圖進行填寫

創建完成后進入項目，右下角彈出的提示點擊右邊的Enable Auto-Import，自動配置

連接數據庫，我用的是Mysql數據庫，準備好有數據的數據庫表

springmvc.xml代碼：

entity學生實體類代碼：

package com.accp.entity;

public class Studentinfo {

private long sid;

private String sname;

private String sgender;

private long sage;

private String saddress;

private String semail;

public long getSid() {

return sid;

}

public void setSid(long sid) {

this.sid = sid;

}

public String getSname() {

return sname;

}

public void setSname(String sname) {

this.sname = sname;

}

public String getSgender() {

return sgender;

}

public void setSgender(String sgender) {

this.sgender = sgender;

}

public long getSage() {

return sage;

}

public void setSage(long sage) {

this.sage = sage;

}

public String getSaddress() {

return saddress;

}

public void setSaddress(String saddress) {

this.saddress = saddress;

}

public String getSemail() {

return semail;

}

public void setSemail(String semail) {

this.semail = semail;

}

}

dao層StudentinfoDao代碼：

package com.accp.dao;

import com.accp.entity.Studentinfo;

import java.util.List;

public interface StudentinfoDao {

ListqueryStudent();

int addStudentinfo(Studentinfo studentinfo);

int deleteStudentinfo(Studentinfo studentinfo);

int updateStudentinfo(Studentinfo studentinfo);

Studentinfo getByStudentId(Studentinfo studentinfo);

}

resources下xml里Studentinfo.xml代碼：

select * from studentinfo;

select * from studentinfo where sid = #{sid}

insert into studentinfo value (default ,#{sname},#{sgender},#{sage},#{saddress},#{semail})

delete from studentinfo where sid = #{sid}

update studentinfo

sname = #{sname},

sgender = #{sgender},

sage = #{sage},

saddress = #{saddress},

semail = #{semail},

service層StudentinfoService代碼：

package com.accp.service;

import com.accp.entity.Studentinfo;

import java.util.List;

public interface StudentinfoService {

ListqueryStudent();

int addStudentinfo(Studentinfo studentinfo);

int deleteStudentinfo(Studentinfo studentinfo);

int updateStudentinfo(Studentinfo studentinfo);

Studentinfo getByStudentId(Studentinfo studentinfo);

}

service層Impl實現類StudentinfoServiceImpl代碼：

package com.accp.service.impl;

import com.accp.dao.StudentinfoDao;

import com.accp.entity.Studentinfo;

import com.accp.service.StudentinfoService;

import org.springframework.stereotype.Service;

import javax.annotation.Resource;

import java.util.List;

@Service

public class StudentinfoServiceImpl implements StudentinfoService {

@Resource

private StudentinfoDao studentinfoDao;

public ListqueryStudent() {

return studentinfoDao.queryStudent();

}

public int addStudentinfo(Studentinfo studentinfo) {

return studentinfoDao.addStudentinfo(studentinfo);

}

public int deleteStudentinfo(Studentinfo studentinfo) {

return studentinfoDao.deleteStudentinfo(studentinfo);

}

public int updateStudentinfo(Studentinfo studentinfo) {

return studentinfoDao.updateStudentinfo(studentinfo);

}

public Studentinfo getByStudentId(Studentinfo studentinfo) {

return studentinfoDao.getByStudentId(studentinfo);

}

}

controller控制層StudentinfoController代碼：

package com.accp.controller;

import com.accp.entity.Studentinfo;

import com.accp.service.StudentinfoService;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;

@Controller

public class StudentinfoController {

@Resource

private StudentinfoService studentinfoService;

@RequestMapping("/showList")

public String showList(Model model){

model.addAttribute("students",studentinfoService.queryStudent());

return "index";

}

@RequestMapping("/JumpAdd")

public String jumpAdd(){

return "add";

}

@RequestMapping("/AddList")

public String addList(Studentinfo studentinfo){

studentinfoService.addStudentinfo(studentinfo);

return "redirect:showList";

}

@RequestMapping("/DeleteS")

public String deleteS(Studentinfo studentinfo){

studentinfoService.deleteStudentinfo(studentinfo);

return "redirect:showList";

}

@RequestMapping("/JumpUpdate")

public String jumpUpdate(Studentinfo studentinfo,Model model){

model.addAttribute("stu",studentinfoService.getByStudentId(studentinfo));

return "update";

}

@RequestMapping("/UpdateS")

public String updateS(Studentinfo studentinfo){

studentinfoService.updateStudentinfo(studentinfo);

return "redirect:showList";

}

}
