Spring MVC 中的多个@PathVariable [英] Multiple @PathVariable in Spring MVC

问题描述

很遗憾无法找到答案，所以希望有人可以提供帮助.

Couldn't find an answer to this unfortunately so hoping someone can help.

在 Spring MVC 3.1.0 中，这是我的方法:

In Spring MVC 3.1.0 here is my method:

@RequestMapping(value = "/{app}/conf/{fnm}", method=RequestMethod.GET)
public ResponseEntity<?> getConf(@PathVariable String app, @PathVariable String fnm) {
    log.debug("AppName:" + app);
    log.debug("fName:" + fnm);
            ...
            return ...
    }

我在网上看过一些例子，理论上有多个@PathVariables 似乎没有问题.

I've seen some examples online and it appears there is no problem having multiple @PathVariables in theory.

但是，当我这样做时，app"和fnm"都包含相同的值(即分配给app"的任何值).

However when I do it, both "app" and "fnm" contain the same value (which is whatever value was assigned to "app").

真的很感激有人对我哪里出错的任何见解吗?

Really appreciate any insight someone may have to where I'm going wrong?

谢谢！

推荐答案

@RequestMapping(value = "/{app}/conf/{fnm}", method=RequestMethod.GET)
public ResponseEntity<?> getConf(@PathVariable("app") String app, @PathVariable("fnm") String fnm) {
   log.debug("AppName:" + app);
   log.debug("fName:" + fnm);
           ...
           return ...
  }

基本上路径变量需要在方法参数中用括号指定.这有帮助吗?

Basically path variables need to be specified with parentheses, in method arguments. Does this help?
