public class ResourceHandler
extends HandlerWrapper

Resource Handler. This handle will serve static content and handle If-Modified-Since headers. No caching is done. Requests for resources that do not exist are let pass (Eg no 404's).

构造方法详细信息

ResourceHandler

public ResourceHandler()

方法详细信息

getMimeTypes

public MimeTypes getMimeTypes()

setMimeTypes

public void setMimeTypes(MimeTypes mimeTypes)

isAliases

public boolean isAliases()

返回：

True if resource aliases are allowed.

setAliases

public void setAliases(boolean aliases)

Set if resource aliases (eg symlink, 8.3 names, case insensitivity) are allowed. Allowing aliases can significantly increase security vulnerabilities. If this handler is deployed inside a ContextHandler, then the ContextHandler.isAliases() takes precedent.

参数：

aliases - True if aliases are supported.

isDirectoriesListed

public boolean isDirectoriesListed()

Get the directory option.

返回：

true if directories are listed.

setDirectoriesListed

public void setDirectoriesListed(boolean directory)

Set the directory.

参数：

directory - true if directories are listed.

isEtags

public boolean isEtags()

返回：

True if ETag processing is done

setEtags

public void setEtags(boolean etags)

参数：

etags - True if ETag processing is done

doStart

public void doStart()
             throws Exception

从类 AggregateLifeCycle 复制的描述

Start the managed lifecycle beans in the order they were added.

覆盖：

类 HandlerWrapper 中的 doStart

抛出：

Exception

AbstractLifeCycle.doStart()

getBaseResource

public Resource getBaseResource()

返回：

Returns the resourceBase.

getResourceBase

public String getResourceBase()

返回：

Returns the base resource as a string.

setBaseResource

public void setBaseResource(Resource base)

参数：

base - The resourceBase to set.

setResourceBase

public void setResourceBase(String resourceBase)

参数：

resourceBase - The base resource as a string.

getStylesheet

public Resource getStylesheet()

返回：

Returns the stylesheet as a Resource.

setStylesheet

public void setStylesheet(String stylesheet)

参数：

stylesheet - The location of the stylesheet to be used as a String.

getCacheControl

public String getCacheControl()

返回：

the cacheControl header to set on all static content.

setCacheControl

public void setCacheControl(String cacheControl)

参数：

cacheControl - the cacheControl header to set on all static content.

getResource

public Resource getResource(String path)
                     throws MalformedURLException

抛出：

MalformedURLException

getResource

protected Resource getResource(HttpServletRequest request)
                        throws MalformedURLException

抛出：

MalformedURLException

getWelcomeFiles

public String[] getWelcomeFiles()

setWelcomeFiles

public void setWelcomeFiles(String[] welcomeFiles)

getWelcome

protected Resource getWelcome(Resource directory)
                       throws MalformedURLException,
                              IOException

抛出：

MalformedURLException

IOException

handle

public void handle(String target,
                   Request baseRequest,
                   HttpServletRequest request,

覆盖：

类 HandlerWrapper 中的 handle

参数：

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

request - The request either as the Request object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Response object if required.

抛出：

IOException

ServletException

doDirectory

protected void doDirectory(HttpServletRequest request,
                           HttpServletResponse response,

                                 Resource resource,
                                 String mimeType)

Set the response headers. This method is called to set the response headers such as content type and content length. May be extended to add additional headers.

参数：

response -

resource -

mimeType -
