jpa查询用法，jpa查询字段开头，jpa查询字段以什么开始

        JPAQueryFactory jpaQueryFactory = new JPAQueryFactory(entityManager);

        QTSscDeptAgPO tSscDeptAgPO = QTSscDeptAgPO.tSscDeptAgPO;
        List fetch = jpaQueryFactory.selectFrom(tSscDeptAgPO)
                .where(tSscDeptAgPO.pwOrgCode.startsWith(Optional.ofNullable(vo.getOrgCode()).orElse("")))
                .fetch();
