REST url @RequestParam编码无法解码为正确的格式（Spring MVC）

Question

I'm writing a Rest controller with Spring MVC, currently I have just one endpoint with one parameter requesting:

@RequestMapping(value = "/city", method = RequestMethod.GET)
@ResponseBody
public List<String> getCities(@RequestParam String name)  {
    ...
}

I'm working with Hungarian city names which can have some special characters (á,é,ő,ű,ú...) - they all come from the database.

When I call the rest endpoint with this:

/serviceoffer/region/city?name=Borsod-Aba%C3%BAj-Zempl%C3%A9n

I get this string into the name:

Borsod-Abaúj-Zemplén

but I should get this:

Borsod-Abaúj-Zemplén

I don't know if it's an encoding/decoding issue, but I tried to decode it without any success.

What could be the solution? Many thanks!

我将tomcat 7更改为tomcat 8，问题已解决...很奇怪...

Since you use Tomcat <= 7 and GET requests, you should change the URIEncoding from the default ISO8859-1 to UTF-8. Change your HTTP connector settings in config/server.xml :

<Connector ... URIEncoding="UTF-8" />
