Class.getResource介绍

[英]Returns the URL of the given resource, or null if the resource is not found. The mapping between the resource name and the URL is managed by the class' class loader.
[中]返回给定资源的URL，如果找不到该资源，则返回null。资源名称和URL之间的映射由类的类加载器管理。

/**
  * Given a {@code resourceName} that is relative to {@code contextClass}, returns a {@code URL}
  * pointing to the named resource.
  *
  * @throws IllegalArgumentException if the resource is not found
  */

  URL url = contextClass.getResource(resourceName);
  checkArgument(
    url != null, "resource %s relative to %s not found.", resourceName, contextClass.getName());
