SpringMVC基本配置

小常规

注解驱动

@Configuration
@ComponentScan(value = "com.superdemo",includeFilters =
        @ComponentScan.Filter(type= FilterType.ANNOTATION,classes = {Controller.class})
    )
public class SpringMVCConfiguration implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        WebMvcConfigurer.super.addResourceHandlers(registry);
        registry.addResourceHandler("/static.img/**").addResourceLocations("/static.img/");
        registry.addResourceHandler("/js/**").addResourceLocations("/js/");
        registry.addResourceHandler("/css/**").addResourceLocations("/css/");
    }
 
    //放行所有资源
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        WebMvcConfigurer.super.configureDefaultServletHandling(configurer);
        configurer.enable();
    }
}

public class ServletContainersInitConfig extends AbstractDispatcherServletInitializer {
    @Override
    protected WebApplicationContext createServletApplicationContext() {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringMVCConfiguration.class);
        return ctx;
    }
 
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
 
    @Override
    protected WebApplicationContext createRootApplicationContext() {
        return null;
    }
}
