spring boot 项目中使用thymeleaf模板的案例分析

时间:2021-05-19

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:

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>

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;@Controllerpublic class PreregController { @Resource PreregMapper preregMapper; @RequestMapping("/listPrereg") public String listPrereg(Model model) { List<Prereg> 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;@Mapperpublic interface PreregMapper {@Select("SELECT * FROM Prereg")List<Prereg> 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;}@Overridepublic 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:

<!DOCTYPE html><html lang="en" xmlns:th="http://pany}"></td> <td th:text="${item.peopleCount}"></td> <td th:text="${item.trans}"></td> </tr> </table> </body></html>

效果图如下:
