Decode EncodeURIComponet using java

Question

I am passing values to server using encodeURIComponent through an AJAX call, but on the server side request.getParameter() is not decoding it automatically. How can I decode the value? I am using spring MVC.

$.ajax({  
    type: "POST",
    url: "test/editTest.do",
    data: "id=" + encodeURIComponent(id)
})

Any help and guidance would be appreciated

Thanks

Answer 1

Add a charset filter as a first filter in your web.xml

<filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Also, you can make sure that your server is configured properly, for tomcat for instance adding URIEncoding to connector

<connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>

will specify the character encoding used to decode the URI. If you're not using tomcat you should find an equivalent for your server
