Question

我有一个spring mongo存储库，其中包含以下方法

@Query(value = "{storeId: ?0, code: ?1, $or: [ { campaignId: ?2}, {campaignId: ''}, {campaignId: null}], $or: [ {$and: [ {'effectiveDate.from': { $lte: ?3}}, {'effectiveDate.to': { $gte: ?3}} ]}, {$and: [ {'effectiveDate.from': { $lte: ?4}}, {'effectiveDate.to': { $gte: ?4}} ]}]}")
List<GiftCard> findByGiftCardExisting(
        String storeId, String code, String campaignId, LocalDateTime from, LocalDateTime to);

使用mongo的控制台测试了查询。但是，在运行应用程序时，我得到一个JSONParseException。经过一番挖掘后，我注意到参数$ 2未按预期绑定。

{storeId: "L_STORE", code: "TESTE1", $or: [ { campaignId: ?2}, {campaignId: ''}, {campaignId: null}], $or: [ {$and: [ {'effectiveDate.from': { $lte: { "$date" : "2017-04-03T03:00:00.000Z"}}}, {'effectiveDate.to': { $gte: { "$date" : "2017-04-03T03:00:00.000Z"}}} ]}, {$and: [ {'effectiveDate.from': { $lte: { "$date" : "2017-04-03T03:00:00.000Z"}}}, {'effectiveDate.to': { $gte: { "$date" : "2017-04-03T03:00:00.000Z"}}} ]}]}

其余参数按预期工作。有人可以指出错误吗？

您的查询存在以下几个问题。

您缺少$or运算符周围的括号，另一个是在使用带有相同（$and）运算符的指定多个表达式时必须使用显式$or。

尝试

@Query(value = "{storeId: ?0, code: ?1, $and:[{$or: [ { campaignId: ?2}, {campaignId: ''}, {campaignId: null}]}, {$or: [ {$and: [ {'effectiveDate.from': { $lte: ?3}}, {'effectiveDate.to': { $gte: ?3}} ]}, {$and: [ {'effectiveDate.from': { $lte: ?4}}, {'effectiveDate.to': { $gte: ?4}} ]}]}]}")
List<GiftCard> findByGiftCardExisting(
    String storeId, String code, String campaignId, LocalDateTime from, LocalDateTime to);

Spring数据mongo没有绑定一些参数
