我试图在条件构建器中创建一个函数，但是执行该命令后，我得到了以下提示。
.setMaximumCategoryLabelWidthRatio(float ratio)}
例外：
CriteriaBuilder builder = manager.getCriteriaBuilder();
CriteriaQuery<RetrospectiveSearchVO> criteriaQuery = builder.createQuery(RetrospectiveSearchVO.class);
Root<Authorization> root = criteriaQuery.from(Authorization.class);
Join<Authorization, MedicalDiagProcedure> medicalDiagProcedureJoin = root.join(Authorization_.medicalDiagProcedures,JoinType.LEFT);
Join<MedicalDiagProcedure, MedicalDiagnosis> medicalDiagJoin = medicalDiagProcedureJoin.join(MedicalDiagProcedure_.medicalDiagnosis,JoinType.LEFT);
Join<MedicalDiagnosis, ReferenceData> medicalDiagRefDataJoin = medicalDiagJoin.join(MedicalDiagnosis_.diagnosis,JoinType.LEFT);
ArrayList<Predicate> conditions = new ArrayList<>();
conditions.add(builder.like(medicalDiagRefDataJoin.get(ReferenceData_.referenceTypeValue), dignosisValue));
Expression<String> functionStringAgg = builder.function( "string_agg", String.class,
medicalDiagRefDataJoin.<String>get("referenceTypeValue"),
builder.parameter(String.class, "delimiter"));
Expression<String> parentExpression = root.get(Authorization_.authorizationNbr);
Predicate parentPredicate = parentExpression.in(claimNbr);
conditions.add(builder.equal(medicalDiagJoin.get(MedicalDiagnosis_.diagType),"F"));
criteriaQuery.where(parentPredicate,builder.and(conditions.toArray(new Predicate[] {})));
criteriaQuery.multiselect(
root.get(Authorization_.authorizationNbr), functionStringAgg);
criteriaQuery.groupBy(root.get(Authorization_.authorizationNbr));
Query query = manager.createQuery(criteriaQuery);
