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

    
    


User List


        number: 
        price: 
        weight: 

    

        
ID
        
Name

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
@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;
    }
}
