javax.el.PropertyNotFoundException: Property ‘XXX’ not found on type bean.XXXXX




解决方案：



1.可能你遇到的错误是“Property ‘xxx’ not found on type java.lang.String”异常

它的意思是String类中没有xxx这个属性，而修改的方法就是：
<c:forEach items="list" var="c" >  
修改成：
<c:forEach items="${list}" var="c" >



2 确保bean属性中有 getter，setter 方法

package com.itheima.springbootmysbatis.model;

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

import java.io.Serializable;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class CharacterInfo implements Serializable {
    private int ID;
    private int UID;
    private int CharacterSN;

    private String name;
    private int clazz;
    private int level;
    private int exp;
    private int ap;
}



3 建议全部的属性名小写

因为EL是读取属性的getter方法的，一般按照属性首字母小写来处理。属性命名最好是小写的，当然首字母一定要小写。



4完整格式
