用于GET url参数的SpringMVC RequestMapping [英] SpringMVC RequestMapping for GET url parameters

问题描述

如何使RequestMapping处理url中的GET参数?例如我有这个网址

How to make the RequestMapping to handle GET parameters in the url? For example i have this url

localhost:8080/MyApplication/spm/gcNkyLXkwv

localhost:8080/MyApplication/spm/gcNkyLXkwv

如何从上述网址获取spm值

how to get the spm value from the above url

推荐答案

可以使用PathVariable完成此操作.我将举个例子.您可以将其合并到示例中

This can be done using PathVariable. I will just give example how it can be done. You can incorporate in your example

假设您想写一个URL来获取某些订单，您可以说

Suppose you want to write a url to fetch some order, you can say

www.mydomain.com/order/123

其中 123 是orderId.

where 123 is orderId.

所以现在您将在spring mvc控制器中使用的网址看起来像

So now the url you will use in spring mvc controller would look like

/order/{orderId}现在可以将订单ID声明为路径变量

/order/{orderId} Now order id can be declared a path variable

@RequestMapping(value = " /order/{orderId}", method=RequestMethod.GET)
public String getOrder(@PathVariable String orderId){
//fetch order
}

如果您使用网址 www.mydomain.com/order/123 ，则 orderId 变量将在春季之前由值123填充

if you use url www.mydomain.com/order/123, then orderId variable will be populated by value 123 by spring

还要注意，PathVariable与requestParam不同，因为pathVariable是URL的一部分.使用请求参数的相同网址看起来像 www.mydomain.com/order?orderId=123

Also note that PathVariable differ from requestParam as pathVariable are part of URL. The same url using request param would look like www.mydomain.com/order?orderId=123
