实际上，HTTP `PUT` 也可以使用同样的技巧。

但这里用 `PATCH` 举例，因为它就是为这种用例设计的。

///

/// note | 注意

注意，输入模型仍会被验证。

因此，如果希望接收的部分更新可以省略所有属性，则需要一个所有属性都标记为可选（带默认值或 `None`）的模型。

为了区分用于**更新**（全部可选）和用于**创建**（必填）的模型，可以参考[更多模型](extra-models.md) 中介绍的思路。

Maven Repository Metadata Model

 This is strictly the model for Maven Repository Metadata, so really just plain objects.

 The metadata file name is:

 * <<<maven-metadata.xml>>> in a remote repository,

import org.apache.maven.api.Packaging;
import org.apache.maven.api.Type;
import org.apache.maven.api.model.Dependency;
import org.apache.maven.api.model.InputLocation;
import org.apache.maven.api.model.Plugin;
import org.apache.maven.api.model.PluginContainer;
import org.apache.maven.api.model.PluginExecution;

import org.apache.maven.api.services.PackagingRegistry;

Stellen wir uns vor, dass das Laden des Modells **eine ganze Weile dauern** kann, da viele **Daten von der Festplatte** gelesen werden müssen. Sie möchten das also nicht für jeden Request tun.

* event
* startup event
* server'ın startup'ı
* shutdown event
* lifespan event

* handler
* event handler
* exception handler
* handle etmek

* model
* Pydantic model
* data model
* database model
* form model
* model object

* class
* base class
* parent class
* subclass
* child class

* class method

* header
* headers

        fields_to_extract = get_cached_model_fields(first_field.field_info.annotation)
        single_not_embedded_field = True
        # If headers are in a Pydantic model, the way to disable convert_underscores
        # would be with Header(convert_underscores=False) at the Pydantic model level
        default_convert_underscores = getattr(
            first_field.field_info, "convert_underscores", True

 * <ol>
 * <li>success - in which case only the model field is set
 * <li>success with warnings - model field + non-error model problems
 * <li>error - no model, but diagnostics
 * <li>error - (partial) model and diagnostics
 * </ol>
 * Could encode these variants as subclasses, but kept in one for now
 *
 * @param <T> the model type
 * @deprecated use {@code org.apache.maven.api.services.ModelBuilder} instead
