SpringMVC RequestMapping用于GET参数 [英] SpringMVC RequestMapping for GET 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

http://localhost:8080/userGrid?_search=false&nd=1351972571018&rows=10&page=1&sidx=id&sord=desc

（来自jqGrid）

(from jqGrid)

我的RequestMapping应该如何？我想使用HttpReqest获取参数

how should my RequestMapping look like? I want to get the parameters using HttpReqest

试过这个：

@RequestMapping("/userGrid")
    public @ResponseBody GridModel getUsersForGrid(HttpServletRequest request)

但它不起作用。

推荐答案

使用 @ RequestParam 因此Spring可以绑定它们，也使用< a href =http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/web/bind/annotation/RequestMapping.html#params%28%29\"rel =noreferrer > @ RequestMapping.params 数组缩小了spring将使用的方法。示例代码：

Use @RequestParam in your method arguments so Spring can bind them, also use the @RequestMapping.params array to narrow the method that will be used by spring. Sample code:

@RequestMapping("/userGrid", 
params = {"_search", "nd", "rows", "page", "sidx", "sort"})
public @ResponseBody GridModel getUsersForGrid(
@RequestParam(value = "_search") String search, 
@RequestParam(value = "nd") int nd, 
@RequestParam(value = "rows") int rows, 
@RequestParam(value = "page") int page, 
@RequestParam(value = "sidx") int sidx, 
@RequestParam(value = "sort") Sort sort) {
// Stuff here
}

这样，如果存在ALL PARAMETERS，Spring将只执行此方法，从而避免空检查和相关内容。

This way Spring will only execute this method if ALL PARAMETERS are present saving you from null checking and related stuff.
