Question

谁有相同的错误以及如何解决？

Java代码：

// For simplify code I left one criteria elemMatch in all criteria.
Criteria expectedCriteria = Criteria.where("tags").all(new Criteria().elemMatch(Criteria.where("localization").is("EN")));
String json = expectedCriteria.getCriteriaObject().toJson();

例外：

Exception in thread "main" org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class org.springframework.data.mongodb.core.query.Criteria.

文档： https://docs.mongodb.com/manual/reference/operator/query/all/#use-all-with-elemmatch

mongo-java-driver版本在复制中：（在所有） -3.4.3 -3.5.0 -3.6.4 -3.7.1 -3.8.2 -3.9.0

适用于代码的Mongo DB脚本：

db.getCollection('devices').find({ 
    "tags": {
        "$all": [{
                "$elemMatch": {
                    "key": "localization",
                    "value": {
                        "$eq": "EN"
                    }
                }
            }
        ]
    }
})

在$ all中使用$ elemMatch时，mongo-java-driver中出现CodecConfigurationException
