在spring MVC中传递非英文字符参数

我在springMVC中传递参数时遇到问题。

@RequestMapping(value = "/", method = RequestMethod.POST)
    public String homePost(Model model, HttpServletRequest request) {
        StringBuilder redirect = new StringBuilder();
        String para = request.getParameter("keyword");

        redirect.append("redirect:/search?" + "cat=0&job="+ para);
        logger.info("Page called: SEARCH; Called parameter: KEYWORD: " + redirect.toString());

        return redirect.toString();
}

在我的控制台中,我可以看到:

  

页面呼叫:搜索;调用参数:KEYWORD:   重定向:/ search?cat = 0& job =lolлолlo

但我的网址是

  

http://localhost:8088/search?cat=0&job=lol%20%20%20%20%20lol

我将所有编码设置为“UTF-8”,并且我尝试使用Cyrillic从列表中搜索,但它会将西里尔字母转换为空格。我可以用拉丁字母搜索。如果我使用西里尔字母手动写入URL,我也可以搜索。 在控制台中,它还显示

  

bind => [%lol lol%]

谢谢。

P.S即使我没有使用StringBuilder,我也有同样的问题。 P.S.S我的web.xml有

<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>
        org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
 </filter>
 <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
 </filter-mapping>

感谢您的回答。我解决了这个问题,如果有人有兴趣的话。 @Alex的链接非常有用。

@RequestMapping(value = "/", method = RequestMethod.POST)
    public String homePost(Model model, HttpServletRequest request) throws UnsupportedEncodingException {
        StringBuilder redirect = new StringBuilder();
        String para = request.getParameter("keyword");

        redirect.append("redirect:/search/" + URLEncoder.encode(para, "UTF-8"));
        logger.info("Page called: SEARCH; Called parameter: KEYWORD: " + redirect.toString());

        return redirect.toString();
    }

获取方法是:

@RequestMapping(value="/search/{keyword}", method = RequestMethod.GET)
    public String job(Model model,@PathVariable String keyword) throws UnsupportedEncodingException {

        String job = URLDecoder.decode(keyword);
        return null;
}
