You are probably missing org.springframework.web.filter.CharacterEncodingFilter . You can add it either via web.xml

<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>
</filter>

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

or via Spring java configuration file:

import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        ....
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        FilterRegistration.Dynamic filter = servletContext.addFilter("characterEncodingFilter", characterEncodingFilter);
        filter.addMappingForUrlPatterns(null, false, "/*");
        .....
    }
}
