获取参数编码 [英] Get Parameter Encoding

问题描述

我在GET请求中使用spring mvc和special chars时遇到问题。请考虑以下方法：

I have a problem using spring mvc and special chars in a GET request. Consider the following method:

@RequestMapping("/update")
public Object testMethod(@RequestParam String name) throws IOException {
    }

我向其发送名称中包含ä的GET请求（德国变音符号），例如。它导致弹簧接收¤，因为浏览器将ä映射到％C3％A4 。

to which I send a GET request with name containing an "ä" (german umlaut), for instance. It results in spring receiving "ä" because the browser maps "ä" to %C3%A4.

那么，我如何才能获得正确的编码字符串作为控制器？

So, how can I get the correct encoded string my controller?

感谢您的帮助！

推荐答案

这个怎么样？它有帮助吗？

What about this? Could it help?

在 web.xml 中：

    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>com.example.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <servlet-name>dispatcher</servlet-name>
    </filter-mapping>

com.example.CharacterEncodingFilter ：

public class CharacterEncodingFilter implements Filter {

    protected String encoding;

    public void init(FilterConfig filterConfig) throws ServletException {
        encoding = filterConfig.getInitParameter("encoding");
    }

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,
            FilterChain filterChain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) servletRequest;
        request.setCharacterEncoding(encoding);

        filterChain.doFilter(servletRequest, servletResponse);
    }

    public void destroy() {
        encoding = null;
    }

}
