​springboot引入静态资源

ctrl+n 全局搜索 (WebMvc)

​

@Override

public void addResourceHandlers(ResourceHandlerRegistry registry) {

if (!this.resourceProperties.isAddMappings()) {

logger.debug("Default resource handling disabled");

return;

}

Duration cachePeriod = this.resourceProperties.getCache().getPeriod();

CacheControl cacheControl = this.resourceProperties.getCache()

.getCachecontrol().toHttpCacheControl();

if (!registry.hasMappingForPattern("/webjars/**")) {

customizeResourceHandlerRegistration(registry

.addResourceHandler("/webjars/**")

.addResourceLocations("classpath:/META-INF/resources/webjars/")

.setCachePeriod(getSeconds(cachePeriod))

.setCacheControl(cacheControl));

}

String staticPathPattern = this.mvcProperties.getStaticPathPattern();

if (!registry.hasMappingForPattern(staticPathPattern)) {

registry.addResourceHandler(staticPathPattern)

.addResourceLocations(getResourceLocations(

this.resourceProperties.getStaticLocations()))

.setCacheControl(cacheControl));

}

}

//配置欢迎页面

@Bean

public WelcomePageHandlerMapping welcomePageHandlerMapping(

ResourceProperties resourceProperties) {

return new WelcomePageHandlerMapping(resourceProperties.getWelcomePage(),

this.mvcProperties.getStaticPathPattern());

}

//配置喜欢的图标

@Configuration

@ConditionalOnProperty(value = "spring.mvc.favicon.enabled", matchIfMissing = true)

public static class FaviconConfiguration {

private final ResourceProperties resourceProperties;

public FaviconConfiguration(ResourceProperties resourceProperties) {

this.resourceProperties = resourceProperties;

}

@Bean

public SimpleUrlHandlerMapping faviconHandlerMapping() {

SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();

mapping.setOrder(Ordered.HIGHEST_PRECEDENCE + 1);

//所有  **/favicon.ico

mapping.setUrlMap(Collections.singletonMap("**/favicon.ico",

faviconRequestHandler()));

return mapping;

}

@Bean

public ResourceHttpRequestHandler faviconRequestHandler() {

ResourceHttpRequestHandler requestHandler = new ResourceHttpRequestHandler();

requestHandler

.setLocations(this.resourceProperties.getFaviconLocations());

return requestHandler;

}

}

所有 /webjars/** ，都去 classpath:/META-INF/resources/webjars/ 找资源；

​webjars：以jar包的方式引入静态资源；​

https://www.webjars.org/ 找到需要引入的资源文件 写到pom中：​

<dependency>

   <groupId>org.webjars</groupId>

   <artifactId>jquery</artifactId>

   <version>3.3.1</version>

</dependency>

​自定义的静态资源存放：ResourceProperties​

"/**" 访问当前项目的任何资源，都去（静态资源的文件夹）找；

​

{

"classpath:/META-INF/resources/", "classpath:/resources/",

"classpath:/static/", "classpath:/public/" };

"/"：当前项目的根路径

自定义图标

命名为favicon.ico，放在静态文件夹下即可！

自定义静态文件存放路径：spring.resources.static-locations=classpath:/qmk
