java - Spring MVC 从 RequestMapping 引用 params 变量

Question

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 传递变量“webletId”，但是如何从参数中引用变量“iconSize”？

非常感谢。

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 { ... }
