Spring boot配置文件映射路径

SpringBoot 内置了tomcat，不用再像ssm那样在tomcat的server.xml文件中配置文件映射路劲。
在spring boot的自定义配置类继承 WebMvcConfigurationSupport ，添加路径映射即可，特别简单！

@Configuration
@MapperScan("com.***.**.*")
public class WebMvcConfig extends WebMvcConfigurationSupport {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //  /uploads/  映射到D盘的uploads文件夹下
        registry.addResourceHandler("/uploads/**").addResourceLocations("file:D:/uploads/");
        //  js css 所在文件static映射，方便页面引用js css文件
        registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
        super.addResourceHandlers(registry);

    }
}
