B站黑马的视频

public class WebMvcConfig extends WebMvcConfigurationSupport {
    /**
     * 设置静态资源映射
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        log.info("开始进行静态资源映射...");
        registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
        registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");
    }
}
但发现无论如何·都无法完成映射

后来换成实现WebMvcConfigurationSupport 接口就可以了

public class WebMvcConfig extends WebMvcConfigurationSupport {/*** 设置静态资源映射* @param registry*/@Overrideprotected void addResourceHandlers(ResourceHandlerRegistry registry) {log.info("开始进行静态资源映射...");registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");}
}
