spring - 为什么 DefaultAnnotationHandlerMapping 被弃用？

Question

在 Spring MVC 中，类 DefaultAnnotationHandlerMapping 已弃用。文档(http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/mvc/annotation/DefaultAnnotationHandlerMapping.html)说:

Deprecated. in Spring 3.2 in favor of RequestMappingHandlerMapping

为什么它被弃用了？ RequestMappingHandlerMapping 修复了该类的哪些实际问题？

Spring Framework 是一个托管在 GitHub 上的开源项目，因此所有这些信息都很容易在代码中找到:

1. 找到有问题的源文件:click
2. 切换到“责备” View :click
3. 查找所有出现的“@Deprecated”以查找关联的提交:click
4. 提交消息提到“SPR-10005”，在 Spring JIRA 上找到它:click
5. JIRA 票证包含指向“版本 3.1.3 中的新增功能”文档的链接:click

The new classes were developed in response to many requests to make annotation controller support classes more customizable and open for extension. Whereas previously you could configure a custom annotated controller method argument resolver, with the new support classes you can customize the processing for any supported method argument or return value type.
