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
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
@NoArgsConstructorpublic class Apple {@Getterprivate Integer number;private String price;private String weight;public void setNumber(Integer number) {this.number = number;}public void setPrice(String price) {//错误： return pricethis.price = price;}public void setWeight(String weight) {//错误： return weightthis.weight = weight;}
}
