spring - WebMvcConfigurationSupport 和 WebMvcConfigurerAdapter 的区别

Question

我想添加资源处理程序。在论坛中，他们使用 WebMvcConfigurationSupport:http://forum.springsource.org/showthread.php?116068-How-to-configure-lt-mvc-resources-gt-mapping-to-take-precedence-over-RequestMapping&p=384066#post384066

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

有什么区别和使用哪一个？两者都有我需要的 addResourceHandlers 方法。

这是我目前的类(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;
    }
}

答案在您上面引用的文档中:

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

简而言之，如果@EnableWebMvc 适合您，则无需进一步查看。
