关于elasticsearch存入自定义类报错，如何解决？(语言-java)

今天虚拟机安装了es6.8.10版本，想要springboot操作es测试一下，结果遇到了无法启动项目的情况

大致看了一下，我认为是自定义类当中bigdecmal类型的问题，说是不能编译私有最终类Bigdecmal什么的

java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.math.BigInteger java.math.BigDecimal.intVal accessible: module java.base does not "opens java.math" to unnamed module @38d8f54a

自定义类：

public class ESGoods{
    private static final long serialVersionUID = 8509683142547327975L;

    /**
     * 商品id列
     */
    @Id
    private Long id;

    /**
     * 商品名称
     */
    @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart")
    private String goodsName;
    /**
     * 分类名称
     */
    @Field(type = FieldType.Keyword)
    private String spuName;
    /**
     * 商品品牌名称
     */
    @Field(type = FieldType.Keyword)
    private String goodsBrandName;
    /**
     * 商品价格
     */
    @Field(type = FieldType.Double)
    private BigDecimal amount;
    /**
     * 商品描述
     */
    @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart")
    private String description;
}

( 因为我用的是jdk17，第一次使用，也不知道是不是跟jdk版本有关 )

######我尝试将字段类型改为Double再运行了一下


/**
     * 商品价格
     */
    @Field(type = FieldType.Double)
    private Double amount;
启动成功

想请教知道的大lao解析一下是为何，越详细越好，感激不尽！
