1:jsp page from form: Here are two mandatory conditions. Must be a post-mode submission. 2: Must have enctype attribute, enctype= "Multipart/form-data"

Introduction of JAR packages in 2:maven Pom.xml

<!--file Upload--

1. <dependency>   
2. <groupid< span class= "tag" >>commons-fileupload</groupid >  
3. < artifactid>commons-fileupload</ artifactid>  
4. <version>1.3.2 </version>  
5. </dependency>   

3: Define the Commonsmultipartresolver file parser under Spring's servlet View parser, which is the time to run the project if no fileuload-related jar package is added.

1. <bean id= "Multipartresolver" class= "Org.springframework.web.multipart.commons.CommonsMultipartResolver" >
       <!--Set the default encoding--
       <property name= "defaultencoding" value= "UTF-8"/>
       <!--upload file maximum size 5m-->
       <property name= "maxuploadsize" value= "5242440"/>
       <!--the maximum size (threshold) allowed for file uploads, below this value, only in memory, exceeding this threshold, generating temporary files on the hard disk--
       <property name= "Maxinmemorysize" value= "4096"/>
       <!--set temporary file save path--
       <property name= "Uploadtempdir" value= "Fileupload/temp"/>
   </bean>

4: Controller class, request processing method parameters must have "Multipartfile file" or "Commonsmultipartfile file", and annotated @requestparam

5://Get file name

String fileName = File.getoriginalfilename ();

Get file type
String FileType = File.getcontenttype ();

Copy to specified location

Return "Success";


It's easier to write than to judge anything, so it can be achieved.
