serviceRequest 情報を取得せず、割り当てに挿入する SRNO を取得しないのはなぜですか? また、次のことを試みると同じ関係で：
EntityManager em = entityManagerFactory.createEntityManager();
Query query = em
.createQuery(
"SELECT assignment FROM SRAssignment assignment WHERE assignment.sraId = :sraId")
.setParameter("sraId", new Long(assignmentId));
List<SRAssignment> assignments = query.getResultList();
SRAssignment sra = (SRAssignment) assignments.get(0);
System.out.println(sra.getSraId());
System.out.println(sra.getEmployee().getEmpNo());
System.out.println("________________________________________");
System.out.println(sra.getServiceRequest().getSrNo());
System.out.println();
em.close();
System.out.println(sra.getServiceRequest().getSrNo());という行にヒットするとすぐに
