使用带有hibernate的Query DSL（Spring Data JPA）来构建一个类似的查询

if( bankId != null ){
        query.where(
            coopMember.personId.bankAccountId.isNotNull().and(
            coopMember.personId.bankAccountId.bankBranch.bankId.eq(bankId))
        );
    }

    return query.fetch();

这里的逻辑很简单：如果有人关联的银行帐户，请按银行ID过滤结果 .

BankAccount 实体的 BankBranch 保存 bankId 整数值 . CoopMember 实体可能有也可能没有 BankAccount

问题是当执行上述QueryDSL查询时，即使进行了非空检查，也会抛出 NullPointerException .

更新

在更改逻辑时，会抛出相同的错误 . 我想知道为什么 bankBranch 不能"null-checked"：

if( bankId != null ){
        query.where(
                coopMember.personId.bankAccountId.isNotNull().and(
                        coopMember.personId.bankAccountId.bankBranch.isNotNull())
        );
    }

抛出stacktrace之后：
