首先打开IDEA，File—>New—>Project创建项目
选择左侧导航栏里的Maven，勾上勾，选择webapp
按如下图进行填写
创建完成后进入项目，右下角弹出的提示点击右边的Enable Auto-Import，自动配置
连接数据库，我用的是Mysql数据库，准备好有数据的数据库表

public class Studentinfo {
private long sid;
private String sname;
private String sgender;
private long sage;
private String saddress;
private String semail;
public long getSid() {

this.sid = sid;

}
public String getSemail() {
return semail;

}
}
dao层StudentinfoDao代码：
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代码：
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层StudentinfoService代码：
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层Impl实现类StudentinfoServiceImpl代码：
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控制层StudentinfoController代码：
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";
}
}
