Example 1 with FileSystemResourceLoader

use of cn.taketoday.core.io.FileSystemResourceLoader in project today-framework by TAKETODAY.

the class AbstractGenericWebContextLoader method configureWebResources.

/**
 * Configures web resources for the supplied web application context (WAC).
 * <h4>Implementation Details</h4>
 * <p>If the supplied WAC has no parent or its parent is not a WAC, the
 * supplied WAC will be configured as the Root WAC (see "<em>Root WAC
 * Configuration</em>" below).
 * <p>Otherwise the context hierarchy of the supplied WAC will be traversed
 * to find the top-most WAC (i.e., the root); and the {@link ServletContext}
 * of the Root WAC will be set as the {@code ServletContext} for the supplied
 * WAC.
 * <h4>Root WAC Configuration</h4>
 * <ul>
 * <li>The resource base path is retrieved from the supplied
 * {@code WebMergedContextConfiguration}.</li>
 * <li>A {@link ResourceLoader} is instantiated for the {@link MockServletContext}:
 * if the resource base path is prefixed with "{@code classpath:}", a
 * {@link DefaultResourceLoader} will be used; otherwise, a
 * {@link FileSystemResourceLoader} will be used.</li>
 * <li>A {@code MockServletContext} will be created using the resource base
 * path and resource loader.</li>
 * <li>The supplied {@link GenericWebServletApplicationContext} is then stored in
 * the {@code MockServletContext} under the
 * {@link WebServletApplicationContext#ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE} key.</li>
 * <li>Finally, the {@code MockServletContext} is set in the
