WebRequestDataBinder.bind介绍

[英]Bind the parameters of the given request to this binder's target, also binding multipart files in case of a multipart request.

This call can create field errors, representing basic binding errors like a required field (code "required"), or type mismatch between value and bean property (code "typeMismatch").

Multipart files are bound via their parameter name, just like normal HTTP parameters: i.e. "uploadedFile" to an "uploadedFile" bean property, invoking a "setUploadedFile" setter method.

The type of the target property for a multipart file can be Part, MultipartFile, byte[], or String. The latter two receive the contents of the uploaded file; all metadata like original file name, content type, etc are lost in those cases.
[中]将给定请求的参数绑定到此绑定器的目标，并在多部分请求的情况下绑定多部分文件。
这个调用可以创建字段错误，表示基本的绑定错误，比如必填字段（代码“required”），或者值和bean属性之间的类型不匹配（代码“typeMismatch”）。
多部分文件通过其参数名绑定，就像普通的HTTP参数一样：即“uploadedFile”到“uploadedFile”bean属性，调用“setUploadedFile”setter方法。
多部分文件的目标属性的类型可以是Part、MultipartFile、byte[]或String。后两个接收上传文件的内容；在这些情况下，原始文件名、内容类型等所有元数据都会丢失。
