QueryDSL抛出无法解决属性异常

Question

我们在项目中使用QueryDSL并添加谓词JPA创建以下查询

[选择交易 来自com.fl.bpm.api.beans.Transaction交易 transaction.thread.fulfProject.process.processLabel =？1并且存在（选择1） 来自transaction.thread.fulfProject.projSub作为transaction_thread_fulfProject_projSub58e1f 其中transaction_thread_fulfProject_projSub58e1f.subscription（选择订阅 来自com.fl.bpm.api.beans.product.subscription订阅 lower（subscription.product.flProduct.productDesc）喜欢？2 escape'！'））和（transaction.thread.fulfProject.isHeld为null或transaction.thread.fulfProject.isHeld =？3）和transaction.thread.fulfProject。 isCancelled =？3且transaction.exitDate为null]

创建所有谓词后，我执行下面的查询，

batIter = batRepo.findAll(builder);

但查询错误，

引起： org.hibernate.QueryException：无法解析属性：订阅：com.fl.bpm.api.beans.Thread。

堆栈跟踪的原因：
