其他两类没有关联。我将两个不相关的类CustomerLimits和DividendUpload通过公共字段

customerNumber

：

        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();
    }

公共列表FindUpLoadedAllByTransactionId和CustomerNumber(
长事务（U id）{
String ql=“选择新的EchequeUpload（c.account.switch.switchId，c.account.accountnumber，c.account.accountType，nvl（d.amount，0），”；
ql+=“d.shortDescription，d.longsdescription，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）来自DividendUpload d，CustomerLimits c，其中d.customerNumber=c.customerNumber和d.transaction_id=？1”；
返回此.entityManager.createQuery（ql）.setParameter（1，
事务id）.setHint（“org.hibernate.cacheable”，
新建布尔值（true））.setHint（“org.hibernate.readOnly”，
新的布尔值（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。事实上，这是非常正确的，所以我在这里不知所措

我想说-从查询中删除那个巨大的构造函数。查询中没有编译时安全性，因此必须手动验证每个参数的类型和正确顺序，等等-这是一个维护地狱

相反，选择从中获取字段的实体，并用纯Java构建对象。最好使用一个构建器，而不是一个有这么多参数的构造函数——这是一种“代码味道”——从查询中删除那个巨大的构造函数。查询中没有编译时安全性，因此必须手动验证每个参数的类型和正确顺序，等等-这是一个维护地狱

没有，他在查询中也有15个参数。我数了两次。但不要介意有一个好的规则：如果你的函数有3个以上的参数，你至少忘记了一个。例如，切勿编写此类API。你没有发给我们的课程是相关的。我认为您使用的某些参数类型错误。特别是检查长和双。你确定所有的长参数都很长（不是int）吗？如果你包含了无参数的构造函数，那么就有两个或者三个构造函数。一个是14，另一个是15。@chinedu，关键是另一个开发人员不应该信任你；）他们应该能够在几秒钟内验证构造函数是否正确。@hvgotcodes:你是对的，这和我说的一样。我只是在维护代码，我不是最初写代码的人。我还没有让它工作。yetNo，他在查询中也有15个参数。我数了两次。但别介意有一条好规则：如果函数有3个以上的参数，那么
