IDEA前端thymeleaf只显示部分数据库问题

news2024/9/21 2:36:41

只显示int类型的number，不显示string类型的price和weight
先看一下apple.html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>User List</title>
</head>
<body>
<h1>User List</h1>

<table>
    <tr>
        <th>ID</th>
        <th>Name</th>
    </tr>
    <tr th:each="item: ${apple}">
        number: <td th:text="${item.number}"></td>
        price: <td th:text="${item.price}"></td>
        weight: <td th:text="${item.weight}"></td>
    </tr>
</table>
</body>
</html>

再在IDEA中验证下是否能查询
在这里插入图片描述
可以查询到，那么就是po.Apple的类型设置错误

package com.appledashboard.po;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.Getter;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor

public class Apple {
    @Getter
    private Integer number;
    private String price;
    private String weight;
    public void setNumber(Integer number) {
        this.number = number;
    }

    public void setPrice(String price) {
    //错误： return price
        this.price = price;
    }

    public void setWeight(String weight) {
     //错误： return weight
        this.weight = weight;
    }
}
