I know this is extremely late to the game, but I wanted to post the additional issue I faced when using mysql, if anyone faces the same issue in future.

As some of the answers mentioned above, setting these in the application.properties will mostly fix the problem

spring.http.multipart.max-file-size=16MB
spring.http.multipart.max-request-size=16MB

I am setting it to 16 MB, because I am using mysql MEDIUMBLOB datatype to store the file.

But after fixing the application.properties, When uploading a file > 4MB gave the error: org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [insert into test_doc(doc_id, duration_of_doc, doc_version_id, file_name, doc) values (?, ?, ?, ?, ?)]; Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.; nested exception is com.mysql.jdbc.PacketTooBigException: Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.

So I ran this command from mysql:

SET GLOBAL max_allowed_packet = 1024*1024*16;

I m using spring-boot-1 3 5 RELEASE and I had the same issue  None of above solutions are not worked for me  But finally adding following property to application properties was fixed the problem   multipart max-file-size 10MB

For Spring Boot 2    make sure you are using spring servlet instead of spring http   --- spring    servlet      multipart        max-file-size  10MB       max-request-size  10MB   If you have to use tomcat  you might end up creating EmbeddedServletContainerCustomizer  which is not really nice thing to do   If you can live without tomat  you could replace tomcat with e g  undertow and avoid this issue at all

Also in Spring boot 1 4  you can add following lines to your application properties to set the file size limit  spring http multipart max-file-size 128KB spring http multipart max-request-size 128KB  for spring boot 2 x and above its spring servlet multipart max-file-size 10MB spring servlet multipart max-request-size 10MB  Worked for me  Source  https   spring io guides gs uploading-files  UPDATE  Somebody asked the differences between the two properties  Below are the formal definitions   MaxFileSize  The maximum size allowed for uploaded files  in bytes  If the size of any uploaded file is greater than this size  the web container will throw an exception  IllegalStateException   The default size is unlimited  MaxRequestSize  The maximum size allowed for a multipart form-data request  in bytes  The web container will throw an exception if the overall size of all uploaded files exceeds this threshold  The default size is unlimited   To explain each  MaxFileSize  The limit for a single file to upload  This is applied for the single file limit only  MaxRequestSize  The limit for the total size of all files in a single upload request  This checks the total limit  Let s say you have two files a txt and b txt for a single upload request  a txt is 5kb and b txt is 7kb so the MaxRequestSize should be above 12kb

To avoid this exception you can take help of VM arguments just as I used in Spring 1 5 8 RELEASE   -Dspring http multipart maxFileSize 70Mb -Dspring http multipart maxRequestSize 70Mb

I found the the solution at Expert Exchange  which worked fine for me    Bean public MultipartConfigElement multipartConfigElement         MultipartConfigFactory factory   new MultipartConfigFactory        factory setMaxFileSize  124MB        factory setMaxRequestSize  124MB        return factory createMultipartConfig        Ref  https   www experts-exchange com questions 28990849 How-to-increase-Spring-boot-Tomcat-max-file-upload-size html

In Spring Boot 2 the spring http multipart changed to spring servlet multipart  https   github com spring-projects spring-boot wiki Spring-Boot-2 0 0-M1-Release-Notes multipart-configuration

User · Answer

You need to set the multipart maxFileSize and multipart maxRequestSize parameters to higher values than the default  This can be done in your spring boot configuration yml files  For example  adding the following to application yml will allow users to upload 10Mb files   multipart      maxFileSize  10Mb     maxRequestSize  10Mb   If the user needs to be able to upload multiple files in a single request and they may total more than 10Mb  then you will need to configure multipart maxRequestSize to a higher value   multipart      maxFileSize  10Mb     maxRequestSize  100Mb   Source  https   spring io guides gs uploading-files

In spring 2 x   Options have changed slightly  So the above answers are almost correct but not entirely   In your application properties file   add the following-  spring servlet multipart max-file-size 10MB spring servlet multipart max-request-size 10MB

There is some difference when we define the properties in the application properties and application yaml   In application yml    spring      http        multipart         max-file-size  256KB        max-request-size  256KB   And in application propeties    spring http multipart max-file-size 128KB spring http multipart max-request-size 128KB   Note   Spring version 4 3 and Spring boot 1 4

If you get a  connection resets  error  the problem could be in the Tomcat default connector maxSwallowSize attribute added from Tomcat 7 0 55  ChangeLog   From Apache Tomcat 8 Configuration Reference     maxSwallowSize    The maximum number of request body bytes  excluding transfer encoding   overhead  that will be swallowed by Tomcat for an aborted upload  An   aborted upload is when Tomcat knows that the request body is going to   be ignored but the client still sends it  If Tomcat does not swallow   the body the client is unlikely to see the response  If not specified   the default of 2097152  2 megabytes  will be used  A value of less   than zero indicates that no limit should be enforced    For Springboot embedded Tomcat declare a TomcatEmbeddedServletContainerFactory   Java 8      Bean public TomcatEmbeddedServletContainerFactory tomcatEmbedded         TomcatEmbeddedServletContainerFactory tomcat   new TomcatEmbeddedServletContainerFactory        tomcat addConnectorCustomizers  TomcatConnectorCustomizer  connector - gt            if   connector getProtocolHandler   instanceof AbstractHttp11Protocol lt   gt                    -1 for unlimited               AbstractHttp11Protocol lt   gt   connector getProtocolHandler    setMaxSwallowSize -1                         return tomcat      Java 7    Bean public TomcatEmbeddedServletContainerFactory tomcatEmbedded         TomcatEmbeddedServletContainerFactory tomcat   new TomcatEmbeddedServletContainerFactory        tomcat addConnectorCustomizers new TomcatConnectorCustomizer               Override         public void customize Connector connector                if   connector getProtocolHandler   instanceof AbstractHttp11Protocol lt   gt                        -1 for unlimited                   AbstractHttp11Protocol lt   gt   connector getProtocolHandler    setMaxSwallowSize -1                                       return tomcat      Or in the Tomcat conf server xml for 5MB   lt Connector port  8080  protocol  HTTP 1 1         connectionTimeout  20000         redirectPort  8443         maxSwallowSize  5242880    gt

More specifically  in your application yml configuration file  add the following to the  spring   section   http      multipart          max-file-size  512MB         max-request-size  512MB   Whitespace is important and you cannot use tabs for indentation

For me nothing of previous works  maybe use application with yaml is an issue here   but get ride of that issue using that   import org springframework boot SpringApplication  import org springframework boot autoconfigure SpringBootApplication  import org springframework boot web servlet MultipartConfigFactory  import org springframework boot web servlet ServletComponentScan  import org springframework context annotation Bean  import org springframework util unit DataSize   import javax servlet MultipartConfigElement    ServletComponentScan  SpringBootApplication public class App       public static void main String   args            SpringApplication run App class  args               Bean     MultipartConfigElement multipartConfigElement             MultipartConfigFactory factory   new MultipartConfigFactory            factory setMaxFileSize DataSize ofBytes 512000000L            factory setMaxRequestSize DataSize ofBytes 512000000L            return factory createMultipartConfig

None of the configuration above worked for me with a Spring application   Implementing this code in the main application class  the one annotated with  SpringBootApplication  did the trick    Bean  EmbeddedServletContainerCustomizer containerCustomizer   throws Exception        return  ConfigurableEmbeddedServletContainer container  - gt                   if  container instanceof TomcatEmbeddedServletContainerFactory                       TomcatEmbeddedServletContainerFactory tomcat    TomcatEmbeddedServletContainerFactory  container                    tomcat addConnectorCustomizers                             connector  - gt                                  connector setMaxPostSize 10000000    10MB                                                                             You can change the accepted size in the statement       connector setMaxPostSize 10000000    10MB
