Java Hibernate:PropertyNotFoundException:找不到XXX的getter

我有一个模型（见下文），Hibernate抱怨它找不到字段

stockId

的getter

修复错误非常简单，但我仍在学习hibernate，不知道它为什么会抛出这个错误？我不尝试从任何地方访问该值，因此我假设hibernate正在尝试在幕后调用它

它是否查看模型中的每个字段，并期望它定义一个getter

或者它是否看到变量

stockId

是私有的，并且要求它有一个getter

谢谢

package com.mkyong.stock.model;

import java.io.Serializable;

public class Stock implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long stockId;
  private String stockCode;
  private String stockName;

  public void setStockCode(String stockCode) {
    this.stockCode = stockCode;
  }

  public void setStockName(String stockName) {
    this.stockName = stockName;
  }
}

EDIT:刚刚修复了上面的错误，现在它也在抱怨找不到setter。看来所有元组/字段都需要定义getter和setter

编辑：根据请求添加错误
