Spring MVC引用RequestMapping中的params变量 [英] Spring MVC referencing params variable from RequestMapping

问题描述

我有以下方法:

@RequestMapping(value = "/path/to/{iconId}", params="size={iconSize}", method = RequestMethod.GET)
public void webletIconData(@PathVariable String iconId, @PathVariable String iconSize, HttpServletResponse response) throws IOException {
    // Implementation here
}

我知道如何使用@PathVariable从RequestMapping中传递变量"webletId"，但是如何从参数中引用变量"iconSize"?

I know how to pass the variable "webletId" from the RequestMapping using the @PathVariable, but how do I reference the variable "iconSize" from params?

非常感谢.

推荐答案

使用@RequestParam:

@RequestMapping(value = "/path/to/{iconId}", method = RequestMethod.GET) 
public void webletIconData(@PathVariable String iconId, 
    @RequestParam("size") String iconSize, 
    HttpServletResponse response) throws IOException { ... }
