QueryDSL uniqueResult() tanımlanmamış

Question

Aşağıdaki kod var:

import com.querydsl.jpa.impl.JPAQuery; 
... 
QCustomer customer = QCustomer.customer; 
JPAQuery query = new JPAQuery(entityManager); 

Customer result = query.from(customer) 
        .where(customer.firstName.eq("Bob")) 
        .uniqueResult(customer); 

Ancak Eclipse o uniqueResult tanımlanmamış olduğunu söylüyor.

sadece ileriyi gitti ve JPAQuery kullanarak kaçınılması ve yerine JPAQueryFactory kullandı. Aşağıda kullandığım yeni kod:

JPAQueryFactory queryFactory = new JPAQueryFactory(entityManager); 

QCustomer customer = QCustomer.customer; 

List<Study> result = queryFactory.selectFrom(customer) 
           .where(customer.firstName.eq("Bob")) 
           .fetchOne();
