Spring MVC UTF-8 Encoding

by

Make sure you register Spring’s CharacterEncodingFilter in your web.xml (must be the first filter in that file).

<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>

If you are on Tomcat you might not have set the URIEncoding in your server.xml. If you don’t set it to UTF-8 it won’t work. Definitely keep the CharacterEncodingFilter. Nevertheless, here’s a concise checklist to follow. It will definitely guide you to make this work.
