ResourcePatternResolver class abstract interface

A ResourceLoader that also finds all resources matching a pattern with wildcards, such as resources:templates/*.html or file:config/**/*.properties.

Use it to load every file of a kind without listing them: all templates, all seed data files, all message bundles. The application context is one, so a constructor parameter of type ResourcePatternResolver receives it.

@Component()
class Templates {
  Templates(this.resources);
  final ResourcePatternResolver resources; // the application context

  // Every mail template shipped in lib/resources/mail/.
  List<Resource> all() => resources.getResources('resources:mail/*.txt');
}

Spring (Java):

@Component
class Templates {
  private final ResourcePatternResolver resources;

  Templates(ResourcePatternResolver resources) {
    this.resources = resources;
  }

  Resource[] all() throws IOException {
    return resources.getResources("resources:mail/*.txt");
  }
}
Implemented types

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

getResource(String location) → Resource
The resource at location. Nothing is read yet, and the resource may not exist: check Resource.exists before reading when it may be missing. Never returns null; an unknown prefix gives a resource that does not exist.
inherited
getResources(String locationPattern) → List<Resource>
All resources matching locationPattern, possibly none. A location without wildcards gives that one resource when it exists.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
