是否可以使用@RequestParam从JSON转换为域对象 [英] Is it possible to convert from JSON to domain object with @RequestParam

问题描述

我正在从JavaScript脚本（AngularJS）执行多部分请求，我将JSON数据作为第一部分，将可选文件作为第二部分。是否可以将@RequestParam（data）自动从JSON转换为我的应用程序中的类？喜欢 @RequestParam（data）狗狗

I am doing a multipart request from a JavaScript script (AngularJS) and I get the JSON data as the first part, and an optional file as the second. Is it possible to have the @RequestParam("data") automatically converted from JSON to a class in my application? Like @RequestParam("data") Dog dog

推荐答案

是的。在对象之前使用@RequestBody注释（ http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestbody ）：

Yes. Use @RequestBody annotation before your object (http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestbody):

public void jsonMethod(@RequestBody Dog dog)

注意：你必须让jackson将json转换为你的自定义对象。杰克逊maven依赖：

Note: you must have jackson to convert json to your custom object. Jackson maven dependency:

<dependency>
   <groupId>org.codehaus.jackson</groupId>
   <artifactId>jackson-mapper-asl</artifactId>
   <version>1.7.1</version>
</dependency>
