Question

我有以下类结构：

class TransactionRelation{
      Transaction req;
      Transaction resp;
      ....
}

class Transaction{
    Long id;
    private Set<TransactionStateHistory> transactionStateHistory;
    ...
}

public class TransactionStateHistory {
    private Long id;    
    private TransactionState transactionState;
}

我需要从req查询TransactionRelation的交易，结果中的每个交易都应为TransactionStateHistory，类型为type1

和相应的响应事务不应该具有TransactionStateHistory with type type2`

JPQL如何建议解决以下任务？

本主题围绕我的主题，但我有点复杂

我需要写这样的东西：

SELECT d FROM Document AS d WHERE: user MEMBER OF d.accessors.attribute
