- org.springframework.web.multipart.support.StandardServletMultipartResolver

All Implemented Interfaces:
MultipartResolver
```
public class StandardServletMultipartResolver
extends Object
implements MultipartResolver
```
Standard implementation of the MultipartResolver interface, based on the Servlet 3.0 Part API. To be added as "multipartResolver" bean to a Spring DispatcherServlet context, without any extra configuration at the bean level (see below).
Note: In order to use Servlet 3.0 based multipart parsing, you need to mark the affected servlet with a "multipart-config" section in web.xml, or with a MultipartConfigElement in programmatic servlet registration, or (in case of a custom servlet class) possibly with a MultipartConfig annotation on your servlet class. Configuration settings such as maximum sizes or storage locations need to be applied at that servlet registration level; Servlet 3.0 does not allow for them to be set at the MultipartResolver level.

3.1

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`cleanupMultipart(MultipartHttpServletRequest request)`	Cleanup any resources used for the multipart handling, like a storage for the uploaded files.
`boolean`	`isMultipart(HttpServletRequest request)`	Determine if the given request contains multipart content.
`MultipartHttpServletRequest`	`resolveMultipart(HttpServletRequest request)`	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.
`void`	`setResolveLazily(boolean resolveLazily)`	Set whether to resolve the multipart request lazily at the time of file or parameter access.

public StandardServletMultipartResolver()
```
- 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.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.

  - isMultipart
```
public boolean isMultipart(HttpServletRequest request)
```
    Description copied from interface: 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.
    Specified by:
    isMultipart in interface MultipartResolver
    Parameters:
    request - the servlet request to be evaluated
    Returns:
    whether the request contains multipart content
  - resolveMultipart
```
public MultipartHttpServletRequest resolveMultipart(HttpServletRequest request)
                                             throws MultipartException
```
    Description copied from interface: 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.
    Specified by:
    resolveMultipart in interface MultipartResolver
    Parameters:
    request - the servlet request to wrap (must be of a multipart content type)
    Returns:
    the wrapped servlet request
    Throws:
    MultipartException - if the servlet request is not multipart, or if implementation-specific problems are encountered (such as exceeding file size limits)
