在spring boot 專案中使用thymeleaf模板；小案例
阿新 • • 發佈：2020-07-26
準備
MySql資料庫，表Prereg，IDEA
資料庫中的表如下所示：
IDEA目錄結構如下：
新增thymeleaf依賴：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
開始新增程式碼：
在controller包新增類“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包下新增對映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<Prereg> findAll(); }
在pojo包下新增類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：定義好變數後，Alt+insert彈出“Generate”,選擇“Getter and Setter”,再選擇toString()即可完成。
最後是寫HTML頁面：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>springboot-thymeleaf demo</title>
</head>
<body>
<table border="1" width="1000">
<thead>
<tr>
<td>學生學號</td>
<td>學生姓名</td>
<td>到達時間</td>
<td>家人陪伴</td>
<td>陪伴數量</td>
<td>交通工具</td>
</tr>
</thead>
<tr th:each="item,eee: ${preregs}">
<td th:text="${item.stuId}"></td>
<td th:text="${item.stuName}"></td>
<td th:text="${item.arrTime}"></td>
<td th:text="${item.isCompany}"></td>
<td th:text="${item.peopleCount}"></td>
<td th:text="${item.trans}"></td>
</tr>
</table>
</body>
</html>
</html>
效果圖如下：
