How to Resolve UTF-8 Encoding Problems in Spring MVC?

Spring MVC UTF-8 Encoding

Problem:

When displaying UTF-8 characters on JSP pages, the resulting characters are encoded incorrectly, despite setting the encoding in both the page and the ModelAndView.

Solution:

To resolve this issue, follow these steps:

1. Register Spring's CharacterEncodingFilter:

   <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> 

2. Set URIEncoding in Tomcat's server.xml:
   If you are using Tomcat, ensure URIEncoding is set to UTF-8 in the server.xml:

   <Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8" />

3. Encode special characters in the controller:
   Use uXXXX encoding for special characters in the controller to avoid encoding issues:

   return new ModelAndView("home", "utftest", "\u00f6lm");

By following these steps, you can ensure correct UTF-8 encoding for characters displayed on your JSP pages within your Spring MVC application.
