1. SpringBoot 静态资源映射规则

webjars:以JAR包的方式引入静态资源;

所有/webjars/**,都去classpath:/META-INF/resources/webjars/目录下加载资源;

/**访问当前项目的任何资源(即静态资源文件夹)
- classpath:/META-INF/resources/
- classpath:/resources/,
- classpath:/static/,
- classpath:/public/,
- /:当前项目的根路径

// WebMvcAutoConfiguration.java@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {    if (!this.resourceProperties.isAddMappings()) {        logger.debug("Default resource handling disabled");        return;    }    Integer cachePeriod = this.resourceProperties.getCachePeriod();    if (!registry.hasMappingForPattern("/webjars/**")) {        customizeResourceHandlerRegistration(registry                .addResourceHandler("/webjars/**")                .addResourceLocations("classpath:/META-INF/resources/webjars/")                .setCachePeriod(cachePeriod));    }    String staticPathPattern = this.mvcProperties.getStaticPathPattern();    if (!registry.hasMappingForPattern(staticPathPattern)) {        customizeResourceHandlerRegistration(                registry.addResourceHandler(staticPathPattern)                        .addResourceLocations(                                this.resourceProperties.getStaticLocations())                        .setCachePeriod(cachePeriod));    }}
