Spring 请求添加 cache

@EnableWebMvc
@Configuration
public class MyWebAppConfigurer implements WebMvcConfigurer 

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) 
    registry.addResourceHandler("/static/**")
            .addResourceLocations("file:/c/downlod" )
            .setCacheControl(CacheControl.maxAge(3, TimeUnit.MINUTES).mustRevalidate().cachePrivate())
            .resourceChain(true);
  

Spring 添加 Etag标签

  /**
   * Etag
   * @return
   */
  @Bean
  public FilterRegistrationBean filterRegistrationBean () 
    ShallowEtagHeaderFilter eTagFilter = new ShallowEtagHeaderFilter();
    //设置为weakETag，默认为false
    // eTagFilter.setWriteWeakETag(true);
    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(eTagFilter);
    registration.addUrlPatterns("/*");
    registration.setOrder(2);
    return registration;
  ```
