Java Spring数据MongoDB按内部对象获取文档
在我的Spring Boot/Spring Data MongoDB项目中，我有以下POJO：Java Spring数据MongoDB按内部对象获取文档,java,spring,mongodb,spring-data,spring-data-mongodb,Java,Spring,Mongodb,Spring Data,Spring Data Mongodb,在我的Spring Boot/Spring Data MongoDB项目中，我有以下POJO： @Document(collection = "decision_analysis") public class DecisionAnalysis { private String id; private DecisionAnalysisRequest decisionAnalysisRequest; private DecisionMatrixPageResponse
@Document(collection = "decision_analysis")
public class DecisionAnalysis {
private String id;
private DecisionAnalysisRequest decisionAnalysisRequest;
private DecisionMatrixPageResponse decisionMatrixPage;
private Date createDate;
private HttpRequestData httpRequestData;

查询是在服务器端运行的，所以您必须从服务器的角度来研究性能 您将达到16MB内存限制，以实现文档连续数据增长 您必须使用点符号到达filterQueries嵌入文档进行比较 如果要匹配其中一个过滤器，请参见下面的示例
@Query("{decisionAnalysisRequest.filterQueries :?0}")
DecisionAnalysis findByDecisionAnalysisRequest(BasicQuery filter);
您应该查看document/embedded document/embedded array字段上的比较条件，以比较整个document/embedded document/embedded array。这是因为它将尝试将mongo中的对象与您作为参数传递给使用equals方法的方法的对象进行比较。如果您的类中没有，它将采用默认的Equals方法，并将失败，因为它进行了深度比较。尝试在DecisionAnalysisRequest类中定义equalsand当然是hashcode方法，不要在equals方法定义中包含filterQueries，您也不应该在哈希代码中包含该字段。另一个解决方案可能是在DecisionAnalysisRequest类中包含一个像id这样的唯一字段，并使用该id进行查询。如果新的唯一字段名为id，那么您的repositoryMethod将类似于findByDecisionAnalysisRequest\u id…@pvpkiran感谢您的回答。为什么我不需要在equals/hashcode方法中包含filterQueries？filterQueries是DecisionAnalysisRequest对象唯一性的重要组成部分。此外，我不能使用任何代理ID字段，根据我的业务逻辑，关键是DecisionAnalysisRequest本身，它包含所有内部数据，包括filterQueries，当然您也可以使用。那么在这种情况下，你应该对每个子字段进行深入的比较我已经尝试过了，但由于某些原因它不起作用谢谢你的回答，但我需要通过DecisionAnalysisRequest对象而不是基本查询来找到DecisionAnalysis。filterQueries只是DecisionAnalysisRequestNp的一部分。好的，那么你需要用相同的字段、顺序和值来传递整个文档。如果在查询中只包含部分filterQueries，您认为它在mongodb端应该如何工作？Spring本质上是试图将您的输入转换为等效的mongo查询。我只是想了解您的用例。我不仅仅包括filterQueries。。我仅以filterQueries为例。我还将完整的DecisionAnalysisRequest与filterQueries一起用于DecisionAnalysis查找。另外，当我说数据将增长时——我的意思是，我将在MongoDB中存储数百万个DecisionAnalysis文档，但这些文档中没有一个会达到16MB的限制。好的。尝试调试以查看在发送完整的DecisionAnalysisRequest时生成的查询，如更新中所示。这应该与你的方法相同。首先，您可以在DecisionAnalysisRequest上创建索引，但我认为，如果您可以将可查询字段标识为与完整文档匹配相反的字段，则会非常有效。
