类 CommonsMultipartResolver

构造器详细资料

• CommonsMultipartResolver

  public CommonsMultipartResolver()

  Constructor for use as bean. Determines the servlet container's temporary directory via the ServletContext passed in as through the ServletContextAware interface (typically by a WebApplicationContext).

  另请参阅:

  setServletContext(javax.servlet.ServletContext), ServletContextAware, WebApplicationContext

• CommonsMultipartResolver

  public CommonsMultipartResolver​(ServletContext servletContext)

  Constructor for standalone usage. Determines the servlet container's temporary directory via the given ServletContext.

  参数:

  servletContext - the ServletContext 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.servlet.http.HttpServletRequest) 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.servlet.ServletFileUpload 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 use

  返回:

  the new ServletFileUpload instance

• setServletContext

  public void setServletContext​(ServletContext servletContext)

  从接口复制的说明: ServletContextAware
  Set the ServletContext 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:

  setServletContext 在接口中 ServletContextAware

  参数:

  servletContext - ServletContext object to be used by this object

  另请参阅:

  InitializingBean.afterPropertiesSet(), ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext)

• isMultipart

  public boolean isMultipart​(HttpServletRequest request)

  从接口复制的说明: MultipartResolver
  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 MultipartResolver

  参数:

  request - the servlet request to be evaluated

  返回:

  whether the request contains multipart content

• resolveMultipart

  public MultipartHttpServletRequest resolveMultipart​(HttpServletRequest request)
                                               throws MultipartException

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

  指定者:

  resolveMultipart 在接口中 MultipartResolver

  参数:

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

  返回:

  the wrapped servlet request

  抛出:

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

  另请参阅:

  MultipartRequest.getFile(java.lang.String), MultipartRequest.getFileNames(), MultipartRequest.getFileMap(), ServletRequest.getParameter(java.lang.String), ServletRequest.getParameterNames(), ServletRequest.getParameterMap()

• parseRequest

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

  Parse the given servlet 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​(HttpServletRequest 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 HTTP request

  返回:

  the encoding for the request (never null)

  另请参阅:

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

• cleanupMultipart

  public void cleanupMultipart​(MultipartHttpServletRequest request)

  从接口复制的说明: MultipartResolver
  Cleanup any resources used for the multipart handling, like a storage for the uploaded files.

  指定者:

  cleanupMultipart 在接口中 MultipartResolver

  参数:

  request - the request to cleanup resources for
