    public Long getDividendId() {

     */
    public void setDividendId(Long dividendId) {
        this.dividendId = dividendId;
    }
}

其他两个类不相关。我通过一个公共字段customerNumber 加入了两个不相关的类 CustomerLimits 和 DividendUpload：

public List<EchequeUpload> findUploadedAllByTransactionIDAndCustomerNumber(
            Long transaction_id) {
        String ql = "select new EchequeUpload(c.account.switch.switchId, c.account.accountnumber, c.account.accountType, nvl(d.amount,0), ";
        ql += "d.shortDescription, d.longDescription, c.accountHolder.name, c.accountHolder.mobile, c.accountHolder.email, nvl(d.tax,0), d.taxState, ";
        ql += "d.batchNo, d.company_id, d.id,d.customerNumber) from DividendUpload d , CustomerLimits c where d.customerNumber=c.customerNumber and d.transaction_id=?1";

        return this.entityManager.createQuery(ql).setParameter(1,
                transaction_id).setHint("org.hibernate.cacheable",
                new Boolean(true)).setHint("org.hibernate.readOnly",
                new Boolean(true)).getResultList();
    }

现在的问题是它一直给我这个错误。 IllegalArgumentException 自然会表明我的构造函数不正确，但它是正确的。其实说的很对，所以我这里一头雾水。

Answer 1

我会说 - 从查询中删除那个巨大的构造函数。您在查询中没有编译时安全性，因此您必须手动验证每个参数的类型和正确的顺序等 - 这是一个维护地狱。

相反，选择要从中获取字段的实体并用纯 Java 构造对象。最好使用 Builder，而不是具有这么多参数的构造函数 - 这是一种“代码味道”

Answer 2

您的 2 个构造函数各有 15 个参数（！！！！！！！！！！！！！！！HEAD EXPLODES！！！！！！！！！！！！！！！）

在您的 hql 构造函数中，您将传递 14。

异常意味着什么。用你拥有的构造函数和你认为你拥有的构造函数写的东西不是写的......另外，正如评论指出的那样，某些类型也很可能是不正确的。
