In this article, the editor introduces in detail "the method of introducing SpringBoot+thymeleaf static resources", the content is detailed, the steps are clear, and the details are handled properly. I hope that this article "the method of introducing SpringBoot+thymeleaf static resources" can help you solve your doubts.

I. Mapping rules of static resources

1. Which directories are mapped?

Classpath:/META-INF/resources/

Classpath:/resources/

Classpath:/static/

Classpath:/public/

/: root path of the current project

We put static resource files (such as jq.js, etc.) in the above five directories, which can be accessed directly (similar to the webapp of the previous web project, which cannot be accessed in other directories.

two。 Why these catalogs?

2.1 just look at the source code

WebMvcAutoConfirarution.java classes automatically configured by SpringBoot:

@ 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)) {

CustomizeResourceHandlerRegistration (

Registry.addResourceHandler (staticPathPattern)

.addResourceLocations (getResourceLocations (

This.resourceProperties.getStaticLocations ())

.setCachePeriod (getSeconds (cachePeriod))

.setCacheControl (cacheControl))

}

}

ResourceProperties

ConfigurationProperties (prefix= "spring.resources", ignoreUnknownFields=false)

Public class ResourceProperties {

/ / We can see the mapping path of static resources

Private static final String [] CLASSPATH_RESOURCE_LOCATIONS= {

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

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

...

}

In general:

The WebMvcAutoConfiguration class automatically registers the following directory for us as a static resource directory, that is, a directory that has direct access to resources.

Classpath:/META-INF/resources/

Classpath:/resources/

Classpath:/static/

Classpath:/public/

/: root path of the current project

Priority is from top to bottom.

So, if there is an index.html,public in the static and an index.html under it, then the index.html under the static will be loaded first because of the priority!
