Get Parameter Encoding

Solution 1:

You're having this problem, because the request differentiates between body encoding and URI encoding. A CharacterEncodingFilter sets the body encoding, but not the URI encoding.

You need to set URIEncoding="UTF-8" as an attribute in all your connectors in your Tomcat server.xml. See here: http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html

Or, alternatively, you can set useBodyEncodingForURI="True".

If you're using the maven tomcat plugin, just add this parameter:

mvn -Dmaven.tomcat.uriEncoding=UTF-8 tomcat:run

Solution 2:

What about this? Could it help?

In your web.xml:

    <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;
    }

}
