SpringBoot:静态资源映射规则解析
作者:互联网
WebMvcAutoConfiguration
public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (!this.resourceProperties.isAddMappings()) {
logger.debug("Default resource handling disabled");
} else {
this.addResourceHandler(registry, "/webjars/**", "classpath:/META-INF/resources/webjars/");
this.addResourceHandler(registry, this.mvcProperties.getStaticPathPattern(), (registration) -> {
registration.addResourceLocations(this.resourceProperties.getStaticLocations());
if (this.servletContext != null) {
ServletContextResource resource = new ServletContextResource(this.servletContext, "/");
registration.addResourceLocations(new Resource[]{resource});
}
});
}
}
1)、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/
localhost:8080/webjars/jquery/3.6.0/jquery.js
在访问的时候只需要写webjars下面资源的名称即可
<dependency>
<groupId>org.webjars</groupId>
<artifactId>jquery</artifactId>
<version>3.6.0</version>
</dependency>
2)"/**"访问当前项目的任何资源(静态资源的文件夹)
"classpath:/META-INF/resources/",
"classpath:/resources/",
"classpath:/static/",
"classpath:/public/"
"/":当前项目的根路径
localhost:8080/abc === 去静态资源文件夹里找abc
3)欢迎页:静态资源文件夹下的所有index.html页面,被"/**"映射
localhost:8080/ 找index页面
4)所有的../favicon.ico 都是在静态资源文件夹下找
5)修改静态资源默认加载位置
spring.web.resources.static-locations=classpath:/hello/,classpath:/test/
