Kan*_* Lu 5 cache-control spring-security spring-boot
我是SpringBoot的新手。
我基于Springboot的示例项目来创建我的项目。我想仅针对js / css文件控制用于缓存的http标头。
我在下面添加了一个js文件test.js，src/resources/static然后在中引用它greeting.html。
然后，我在StackOverflow上遵循一些答案，并添加WebMvcConfiguration.java和WebSecurityConfig.java，但它对我不起作用。
我确定WebMvcConfiguration和WebSecurityConfig不应一起使用，或者我配置有误。我更喜欢使用Java Config而不是XML的解决方案。
我打开ChromeDevTool来检查服务器的响应。响应http标头是
Accept-Ranges:bytes
Cache-Control:no-store
Content-Length:20
Content-Type:application/javascript
Date:Thu, 02 Feb 2017 10:53:14 GMT
Expires:
Last-Modified:Thu, 02 Feb 2017 10:52:49 GMT
Pragma:
谢谢！
更新：当我删除时WebSecurityConfig，我得到以下标题
Accept-Ranges:bytes
Cache-Control:no-store
Content-Length:20
Content-Type:application/javascript
Date:Thu, 02 Feb 2017 11:14:51 GMT
Last-Modified:Thu, 02 Feb 2017 11:14:20 GMT
greeting.html
<!DOCTYPE HTML>

WebMvcConfiguration.java
@EnableWebMvc
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/test.js").addResourceLocations("classpath:/resources/").setCachePeriod(31556926);
}
}
WebSecurityConfig.java
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.headers()
.defaultsDisabled()
.cacheControl();
}
}
现代 SpringBoot（至少在 2018 年，不确定何时添加），具有管理此功能的属性：
spring.resources.cache.cachecontrol.cache-private= # Indicate that the response message is intended for a single user and must not be stored by a shared cache.
spring.resources.cache.cachecontrol.cache-public= # Indicate that any cache may store the response.
spring.resources.cache.cachecontrol.max-age= # Maximum time the response should be cached, in seconds if no duration suffix is not specified.
spring.resources.cache.cachecontrol.must-revalidate= # Indicate that once it has become stale, a cache must not use the response without re-validating it with the server.
spring.resources.cache.cachecontrol.no-cache= # Indicate that the cached response can be reused only if re-validated with the server.
spring.resources.cache.cachecontrol.no-store= # Indicate to not cache the response in any case.
spring.resources.cache.cachecontrol.no-transform= # Indicate intermediaries (caches and others) that they should not transform the response content.
spring.resources.cache.cachecontrol.proxy-revalidate= # Same meaning as the "must-revalidate" directive, except that it does not apply to private caches.
spring.resources.cache.cachecontrol.s-max-age= # Maximum time the response should be cached by shared caches, in seconds if no duration suffix is not specified.
spring.resources.cache.cachecontrol.stale-if-error= # Maximum time the response may be used when errors are encountered, in seconds if no duration suffix is not specified.
spring.resources.cache.cachecontrol.stale-while-revalidate= # Maximum time the response can be served after it becomes stale, in seconds if no duration suffix is not specified.
