我使用Spring Boot 2和Spring Security以及Thymeleaf。我有一个MVC和REST的设置。

我搜索一种缓存JavaScript,图像和CSS文件的方法。

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MultiHttpSecurityConfig {
    ...

    @Configuration
    @Order(1)
    public class RestWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
           ...
    }


    @Configuration
    @Order(2)
    public class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.authenticationEventPublisher(authenticationEventPublisher).userDetailsService(userDetailsService)
                    .passwordEncoder(passwordEncoder);
        }

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .antMatchers("/css/**", "/webjars/**", "/js/**", "/img/**", "/")
                    .permitAll().anyRequest().authenticated().and().formLogin().loginPage("/login").permitAll()
                    .successHandler(new CustomAuthenticationSuccessHandler())
                    .and().logout().logoutUrl("/logout").logoutSuccessHandler(new CustomLogoutHandler())
                    .logoutSuccessUrl("/login").and().csrf().disable();
        }
    }

}

我创建了这个类:

@EnableWebMvc
public class MvcConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/js/**", "/webjars/**", "/img/**") 
                .addResourceLocations("/js/", "/webjars/", "/img/") 
                .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS));
    }
}

同样的结果,浏览器每次都会下载所有文件。

src/main/resources下我有:

static  
    css  
    img  
    js  

templates  

修改

响应标题:

Accept-Ranges:bytes
Cache-Control:no-cache, no-store, max-age=0, must-revalidate
Content-Length:95821
Content-Type:application/javascript
Date:Fri, 26 Jan 2018 15:40:55 GMT
Expires:0
Last-Modified:Fri, 02 Jun 2017 12:55:44 GMT
Pragma:no-cache
X-Content-Type-Options:nosniff
X-Frame-Options:DENY
X-XSS-Protection:1; mode=block

修改2

我在FormLoginWebSecurityConfigurerAdapter课程中添加了

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/css/**", "/webjars/**", "/js/**", "/img/**");
}

同样的结果。

好的,让它适用于资源中的css,js

mvc config更改为

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/js/**", "/webjars/**", "/resources/img/**") 
                .addResourceLocations("/resources/js/", "/webjars/", "/resources/img/") 
                .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS));
    }

似乎不需要修改FormLoginWebSecurityConfigurerAdapter antMachers来添加资源......

尝试在Spring Boot主类(@SpringBootApplication)中添加以下代码

@Bean
public WebMvcConfigurerAdapter webConfigurer () {
      return new WebMvcConfigurerAdapter() {
          @Override
          public void addResourceHandlers (ResourceHandlerRegistry registry) {
              registry.addResourceHandler("/static/js/**")
                      .addResourceLocations("/static/js/")
                      .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS));
              registry.addResourceHandler("/static/images/**")
              .addResourceLocations("/static/images/")
              .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS));
              registry.addResourceHandler("/static/css/**")
              .addResourceLocations("/static/css/")
              .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS));
          }
      };
}

文件位于以下路径中: enter image description here

您可以添加高速缓存是私有的还是公共的,或者必须重新验证 setCacheControl(CacheControl.maxAge(365,TimeUnit.DAYS).cachePrivate()。mustRevalidate())
