我想，没关系。但有一件事referencedColumnName是CustomerSurvey。

更改referencedColumnName="surveyId"为referencedColumnName="SERVEYID"。使用大写字母，因为您在CustomerSurvey实体（Previous Post）中使用大写字母。

你可以参考这里。

更新答案：

当我检查您的查询surveyResponse.getAverageRatings时，缺少AVG(ratings). 我认为，应该AVG(surveyResponse.ratings)。

SELECT AVG(surveyResponse.ratings) FROM SurveyResponse surveyResponse WHERE surveyResponse.customerSurvey.surveyId = :surveyId
