All Implemented Interfaces:
Aware, PortletContextAware, PortletMultipartResolver
```
public class CommonsPortletMultipartResolver
extends CommonsFileUploadSupport
implements PortletMultipartResolver, PortletContextAware
```
PortletMultipartResolver implementation for Apache Commons FileUpload 1.2 or above.
Provides "maxUploadSize", "maxInMemorySize" and "defaultEncoding" settings as bean properties (inherited from CommonsFileUploadSupport). See corresponding PortletFileUpload / DiskFileItemFactory properties ("sizeMax", "sizeThreshold", "headerEncoding") for details in terms of defaults and accepted values.
Saves temporary files to the portlet container's temporary directory. Needs to be initialized either by an application context or via the constructor that takes a PortletContext (for standalone usage).

2.0

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`cleanupMultipart(MultipartActionRequest request)`	Cleanup any resources used for the multipart handling, such as storage for any uploaded file(s).
`protected String`	`determineEncoding(ActionRequest request)`	Determine the encoding for the given request.
`boolean`	`isMultipart(ActionRequest request)`	Determine if the given request contains multipart content.
`protected org.apache.commons.fileupload.FileUpload`	`newFileUpload(org.apache.commons.fileupload.FileItemFactory fileItemFactory)`	Initialize the underlying `org.apache.commons.fileupload.portlet.PortletFileUpload` instance.
`protected CommonsFileUploadSupport.MultipartParsingResult`	`parseRequest(ActionRequest request)`	Parse the given portlet request, resolving its multipart elements.
`MultipartActionRequest`	`resolveMultipart(ActionRequest request)`	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.
`void`	`setPortletContext(PortletContext portletContext)`	Set the PortletContext that this object runs in.
`void`	`setResolveLazily(boolean resolveLazily)`	Set whether to resolve the multipart request lazily at the time of file or parameter access.

- Constructor Detail
  - 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).
    See Also:
    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.
    Parameters:
    portletContext - the PortletContext to use
- Method Detail
  - 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.
    Specified by:
    newFileUpload in class CommonsFileUploadSupport
    Parameters:
    fileItemFactory - the Commons FileItemFactory to build upon
    Returns:
    the new PortletFileUpload instance
  - setPortletContext
```
public void setPortletContext(PortletContext portletContext)
```
    Description copied from interface: 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.
    Specified by:
    setPortletContext in interface PortletContextAware
    Parameters:
    portletContext - PortletContext object to be used by this object
  - isMultipart
```
public boolean isMultipart(ActionRequest request)
```
    Description copied from interface: 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.
    Specified by:
    isMultipart in interface PortletMultipartResolver
    Parameters:
    request - the portlet request to be evaluated
    Returns:
    whether the request contains multipart content
  - resolveMultipart
```
public MultipartActionRequest resolveMultipart(ActionRequest request)
                                        throws MultipartException
```
    Description copied from interface: 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.
    Specified by:
    resolveMultipart in interface PortletMultipartResolver
    Parameters:
    request - the portlet request to wrap (must be of a multipart content type)
    Returns:
    the wrapped portlet request
    Throws:
    MultipartException - if the portlet request is not multipart, or if implementation-specific problems are encountered (such as exceeding file size limits)
    See Also:
    MultipartRequest.getFile(java.lang.String), MultipartRequest.getFileNames(), MultipartRequest.getFileMap(), PortletRequest.getParameter(java.lang.String), PortletRequest.getParameterNames(), PortletRequest.getParameterMap()
  - parseRequest
```
protected CommonsFileUploadSupport.MultipartParsingResult parseRequest(ActionRequest request)
                                                                throws MultipartException
```
    Parse the given portlet request, resolving its multipart elements.
    Parameters:
    request - the request to parse
    Returns:
    the parsing result
    Throws:
    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.
    Parameters:
    request - current portlet request
    Returns:
    the encoding for the request (never null)
    See Also:
    ClientDataRequest.getCharacterEncoding(), CommonsFileUploadSupport.setDefaultEncoding(java.lang.String)
  - cleanupMultipart
```
public void cleanupMultipart(MultipartActionRequest request)
```
    Description copied from interface: PortletMultipartResolver
    Cleanup any resources used for the multipart handling, such as storage for any uploaded file(s).
    Specified by:
    cleanupMultipart in interface PortletMultipartResolver
    Parameters:
    request - the request to cleanup resources for

Constructor	Description
`CommonsPortletMultipartResolver()`	Constructor for use as bean.
