所有已实现的接口：

StaticContentLoader

public class DefaultStaticContentLoader
extends Object
implements StaticContentLoader

Default implementation to server static content

This class is used to serve common static content needed when using various parts of Struts, such as JavaScript files, CSS files, etc. It works by looking for requests to /struts/* (or /static/*), and then mapping the value after "/struts/" to common packages in Struts and, optionally, in your class path. By default, the following packages are automatically searched:

• org.apache.struts2.static
• template
• static

This means that you can simply request /struts/xhtml/styles.css and the XHTML UI theme's default stylesheet will be returned. Likewise, many of the AJAX UI components require various JavaScript files, which are found in the org.apache.struts2.static package. If you wish to add additional packages to be searched, you can add a comma separated (space, tab and new line will do as well) list in the filter init parameter named "packages". Be careful, however, to expose any packages that may have sensitive information, such as properties file with database access credentials.
