Morphia，MongoDB，Q类和执行更新

Question

我有一个使用MongoDB的大型Spring Boot项目。大多数工作是使用Spring Data存储库类完成的。这些很棒。但是有时候我想做一些Spring Data仓库接口不容易支持的事情。在那种情况下，我使用RepositoryCutomInterface添加其他方法。一切都很好。现在，我正在使用自动连接到RepositoryCustomInterface的MongoOperations对象。有了那个MongoOperations对象，我就可以继续做我想做的事情。

但是，由于它的类型安全性和其他优点，我真的很想使用Morphia。 我在项目中进行了设置，它正在生成Q类并为我创建一个数据存储区和Morphia。我已经成功地将RepositoryCustomInterface中的内容用于各种查询。

我想做的是弄清楚如何执行更新。我详细阅读了Morphia文档，而MongoDB上的这一节却没有提到进行更新。

例如，我想这样做：

ParamExpression

但这不是有效的代码。 set（）方法需要一个imageCapture.deleted，而BooleanPath是一个<?xml version="1.0" encoding="UTF-8"?> <?import com.jfoenix.controls.JFXButton?> <?import java.lang.String?> <?import java.net.URL?> <?import javafx.geometry.Insets?> <?import javafx.scene.control.Label?> <?import javafx.scene.image.Image?> <?import javafx.scene.image.ImageView?> <?import javafx.scene.layout.AnchorPane?> <?import

我看到可以从数据存储区创建UpdateOperations。但是，这似乎没有使用Q类。

我到处搜索过，但找不到精品，我想知道这是否可行。 欢迎任何建议。
