类 CommonsPortletMultipartResolver

构造器详细资料

• CommonsPortletMultipartResolver

  public CommonsPortletMultipartResolver()

  Constructor for use as bean. Determines the portlet container's temporary directory via the PortletContext passed in as through the PortletContextAware interface (typically by an ApplicationContext).

  另请参阅:

  setPortletContext(javax.portlet.PortletContext), PortletContextAware

• CommonsPortletMultipartResolver

  public CommonsPortletMultipartResolver​(PortletContext portletContext)

  Constructor for standalone usage. Determines the portlet container's temporary directory via the given PortletContext.

  参数:

  portletContext - the PortletContext to use

方法详细资料

• setResolveLazily

  public void setResolveLazily​(boolean resolveLazily)

  Set whether to resolve the multipart request lazily at the time of file or parameter access.

  Default is "false", resolving the multipart elements immediately, throwing corresponding exceptions at the time of the resolveMultipart(javax.portlet.ActionRequest) call. Switch this to "true" for lazy multipart parsing, throwing parse exceptions once the application attempts to obtain multipart files or parameters.

• newFileUpload

  protected org.apache.commons.fileupload.FileUpload newFileUpload​(org.apache.commons.fileupload.FileItemFactory fileItemFactory)

  Initialize the underlying org.apache.commons.fileupload.portlet.PortletFileUpload instance. Can be overridden to use a custom subclass, e.g. for testing purposes.

  指定者:

  newFileUpload 在类中 CommonsFileUploadSupport

  参数:

  fileItemFactory - the Commons FileItemFactory to build upon

  返回:

  the new PortletFileUpload instance

• setPortletContext

  public void setPortletContext​(PortletContext portletContext)

  从接口复制的说明: PortletContextAware
  Set the PortletContext that this object runs in.

  Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

  指定者:

  setPortletContext 在接口中 PortletContextAware

  参数:

  portletContext - PortletContext object to be used by this object

• isMultipart

  public boolean isMultipart​(ActionRequest request)

  从接口复制的说明: PortletMultipartResolver
  Determine if the given request contains multipart content.

  Will typically check for content type "multipart/form-data", but the actually accepted requests might depend on the capabilities of the resolver implementation.

  指定者:

  isMultipart 在接口中 PortletMultipartResolver

  参数:

  request - the portlet request to be evaluated

  返回:

  whether the request contains multipart content

• resolveMultipart

  public MultipartActionRequest resolveMultipart​(ActionRequest request)
                                          throws MultipartException

  从接口复制的说明: PortletMultipartResolver
  Parse the given portlet request into multipart files and parameters, and wrap the request inside a MultipartActionRequest object that provides access to file descriptors and makes contained parameters accessible via the standard PortletRequest methods.

  指定者:

  resolveMultipart 在接口中 PortletMultipartResolver

  参数:

  request - the portlet request to wrap (must be of a multipart content type)

  返回:

  the wrapped portlet request

  抛出:

  MultipartException - if the portlet request is not multipart, or if implementation-specific problems are encountered (such as exceeding file size limits)

• parseRequest

  protected CommonsFileUploadSupport.MultipartParsingResult parseRequest​(ActionRequest request)
                                                                  throws MultipartException

  Parse the given portlet request, resolving its multipart elements.

  参数:

  request - the request to parse

  返回:

  the parsing result

  抛出:

  MultipartException - if multipart resolution failed.

• determineEncoding

  protected String determineEncoding​(ActionRequest request)

  Determine the encoding for the given request. Can be overridden in subclasses.

  The default implementation checks the request encoding, falling back to the default encoding specified for this resolver.

  参数:

  request - current portlet request

  返回:

  the encoding for the request (never null)

  ClientDataRequest.getCharacterEncoding(), CommonsFileUploadSupport.setDefaultEncoding(java.lang.String)

• cleanupMultipart

  public void cleanupMultipart​(MultipartActionRequest request)

  从接口复制的说明: PortletMultipartResolver
  Cleanup any resources used for the multipart handling, such as storage for any uploaded file(s).

  指定者:

  cleanupMultipart 在接口中 PortletMultipartResolver

  参数:

  request - the request to cleanup resources for
