如何在Spring MVC中显式获取post数据？ [英] How to explicitly obtain post data in Spring MVC?

问题描述

有没有办法获取帖子数据本身？我知道spring处理将数据绑定到java对象。但是，考虑到我要处理的两个字段，如何获取该数据？

Is there a way to obtain the post data itself? I know spring handles binding post data to java objects. But, given two fields that I want to process, how can I obtain that data?

例如，假设我的表单有两个字段：

For example, suppose my form had two fields:

 <input type="text" name="value1" id="value1"/>
 <input type="text" name="value2" id="value2"/>

我如何在控制器中检索这些值？

How would I go about retrieving those values in my controller?

推荐答案

如果您正在使用其中一个内置控制器实例，那么控制器方法的其中一个参数将是请求对象。您可以调用 request.getParameter（value1）来获取POST（或PUT）数据值。

If you are using one of the built-in controller instances, then one of the parameters to your controller method will be the Request object. You can call request.getParameter("value1") to get the POST (or PUT) data value.

如果您使用的是Spring MVC注释，则可以在方法的参数中添加带注释的参数：

If you are using Spring MVC annotations, you can add an annotated parameter to your method's parameters:

@RequestMapping(value = "/someUrl")
public String someMethod(@RequestParam("value1") String valueOne) {
 //do stuff with valueOne variable here
}
