如何从云firestore中检索List<Map<String、Object>>并将其转换为自定义模型？

// 引入Firestore的相关依赖库
import com.google.cloud.firestore.Firestore;
import com.google.cloud.firestore.FirestoreOptions;
import com.google.cloud.firestore.QueryDocumentSnapshot;

// 初始化Firestore
FirestoreOptions firestoreOptions = FirestoreOptions.getDefaultInstance().toBuilder()
        .setProjectId("your-project-id")
        .build();
Firestore firestore = firestoreOptions.getService();

// 创建自定义模型类
public class CustomModel {
    private String field1;
    private int field2;
    
    // 构造函数和getter/setter方法省略
}

// 从云Firestore中检索数据并转换为自定义模型
List<CustomModel> customModels = new ArrayList<>();
firestore.collection("your-collection")
        .get()
        .get()
        .forEach(document -> {
            Map<String, Object> data = document.getData();
            CustomModel customModel = new CustomModel();
            customModel.setField1((String) data.get("field1"));
            customModel.setField2((int) data.get("field2"));
            customModels.add(customModel);
        });
