本文介绍如何在JavaServer Faces (JSF)应用中整合PrettyFaces，实现更优雅的URL管理和页面导航。内容覆盖了如何通过action methods、commandLink及commandButton组件进行导航，并提供了非JSF环境下实现PrettyFaces URL重定向的方法。

Integrating with JSF action methods （和JSF action methods的整合）

在action method中返回 return "pretty:store"; 你应该看的懂吧。它会指向谁

Integrating with JSF commandLink and commandButton

Note that if the specified URL-mapping ID requires any parameters, the current values found in the required managed bean locations will be used when navigating.

<h:commandLink action="pretty:home"> Go home. </h:commandLink>

Navigating directly from a command component is most commonly used for refreshing a page:

<h:commandLink action="pretty:"> Refresh this page. </h:commandLink>

Redirecting from non-JSF application Java code

从非JSF环境指向 prettyfaces掌管的URL

public class CustomRedirector 
{
	public void redirect(HttpServletRequest request, HttpServletResponse response, 
							String mappingId, Map<String, String[]>... params)
	{
		PrettyContext context = PrettyContext.getCurrentInstance(request);
		PrettyURLBuilder builder = new PrettyURLBuilder();
		
		URLMapping mapping = context.getConfig().getMappingById(mappingId);
		String targetURL = builder.build(mapping, params);
		
		targetURL = response.encodeRedirectURL(targetURL);
		response.sendRedirect(targetURL);
	}		
}
