准备
MySql数据库,表Prereg,IDEA
数据库中的表如下所示:

IDEA目录结构如下:

添加thymeleaf依赖:

org.springframework.boot
spring-boot-starter-thymeleaf

开始添加代码:
在controller包添加类“PreregController”

package com.example.demo.controller;

import com.example.demo.mapper.PreregMapper;
import com.example.demo.pojo.Prereg;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import java.util.List;

@Controller
public class PreregController {
@Resource
PreregMapper preregMapper;

@RequestMapping("/listPrereg")
public String listPrereg(Model model)
{
List preregs=preregMapper.findAll();
model.addAttribute("preregs",preregs);
return "listPrereg";
}
}

 

在Mapper包下添加映射interface:“PreregMapper”

package com.example.demo.mapper;

import com.example.demo.pojo.Prereg;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration;
import java.util.List;

@Mapper
public interface PreregMapper {
@Select("SELECT * FROM Prereg")
List findAll();
}

 

在pojo包下添加类Prereg:

package com.example.demo.pojo;

import java.util.Date;

public class Prereg {
private String StuId;
private String StuName;
private String Trans;
private int IsCompany;
private int PeopleCount;
private Date ArrTime;

public String getStuId() {
return StuId;
}

public void setStuId(String stuId) {
StuId = stuId;
}

public String getStuName() {
return StuName;
}

public void setStuName(String stuName) {
StuName = stuName;
}

public String getTrans() {
return Trans;
}

public void setTrans(String trans) {
Trans = trans;
}

public int getIsCompany() {
return IsCompany;
}

public void setIsCompany(int isCompany) {
IsCompany = isCompany;
}

public int getPeopleCount() {
return PeopleCount;
}

public void setPeopleCount(int peopleCount) {
PeopleCount = peopleCount;
}

public Date getArrTime() {
return ArrTime;
}

public void setArrTime(Date arrTime) {
ArrTime = arrTime;
}

@Override
public String toString() {
return "Prereg{" +
"StuId=‘" + StuId + ‘\‘‘ +
", StuName=‘" + StuName + ‘\‘‘ +
", Trans=‘" + Trans + ‘\‘‘ +
", IsCompany=" + IsCompany +
", PeopleCount=" + PeopleCount +
", ArrTime=" + ArrTime +
‘}‘;
}
}

 

注:小技巧:定义好变量后,Alt+insert弹出“Generate”,选择“Getter and Setter”,再选择toString()即可完成。

最后是写HTML页面:

springboot-thymeleaf demo
学生学号 学生姓名 到达时间 家人陪伴 陪伴数量 交通工具

效果图如下:
