MongoDb条件查询LTE无法用于数字

时间：2019-03-21 18:53:33

标签： java spring spring-data-jpa mongodb-query spring-data 

  query.addCriteria(Criteria.where(x.getKey()).lte(3));

lte方法接受数组或数组列表或字符串参数。参数类型为Object，因此它应该接受数字对象，但不能接受。如果我已传递任何其他类型，则查询将不会返回任何结果。它应该是数字，但出现一个奇怪的错误。

Throws 
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.util.ArrayList<?>] to type [java.util.Map<?, ?>] for value '[{ "category" : "disType", "subCategory" : ["dinner", "lunch"] }, { "category" : "mainIngredient", "subCategory" : ["meat"] }]'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<?, ?>]

您编写的查询是正确的，但是响应序列化时出错。

  

org.springframework.web.util.NestedServletException：请求   处理失败；嵌套异常为   org.springframework.core.convert.ConversionFailedException：失败   将类型[java.util.ArrayList]转换为类型[java.util.Map]的值'[{“ category”：“ disType”，“ subCategory”：[“ dinner”，   ““午餐”]}，{”类别“：” mainIngredient“，” subCategory“：[”肉“]   }]';嵌套异常为   org.springframework.core.convert.ConverterNotFoundException：否   发现可以将类型[java.lang.String]转换为   输入[java.util.Map]

验证您如何存储此查询的响应。
