Spring – Difference between WebMvcConfigurationSupport and WebMvcConfigurerAdapter

springspring-mvc

I would like to add resource handlers. In the forum they use WebMvcConfigurationSupport: http://forum.springsource.org/showthread.php?116068-How-to-configure-lt-mvc-resources-gt-mapping-to-take-precedence-over-RequestMapping&p=384066#post384066

and docs say WebMvcConfigurerAdapter: http://static.springsource.org/spring/docs/3.2.x/javadoc-api/org/springframework/web/servlet/config/annotation/EnableWebMvc.html

What's the difference and which one to use? Both has the addResourceHandlers method I need.

This is my current class:

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    public @Override void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources");
    }

    public @Bean TilesViewResolver tilesViewResolver() {
        return new TilesViewResolver();
    }

    public @Bean TilesConfigurer tilesConfigurer() {
        TilesConfigurer ret = new TilesConfigurer();
        ret.setDefinitions(new String[] { "classpath:tiles.xml" });
        return ret;
    }
}

Best Answer

The answer is in the doc you referenced above:

If the customization options of WebMvcConfigurer do not expose something you need to configure, consider removing the @EnableWebMvc annotation and extending directly from WebMvcConfigurationSupport overriding selected @Bean methods

In short, if @EnableWebMvc works for you, there is no need to look any further.
