I'm developing application based on Spring Boot and AngularJS using JHipster. My question is how to set max size of uploading files?
If I'm trying to upload to big file I'm getting this information in console:
DEBUG 11768 --- [io-8080-exec-10] c.a.app.aop.logging.LoggingAspect:
Enter: com.anuglarspring.app.web.rest.errors.ExceptionTranslator.processRuntimeException() with argument[s] =
[org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException:
org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.]
And server response with status 500.
How to set that?
This question is related to
tomcat
file-upload
spring-boot
jhipster
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();
}
}
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 -> {
if ((connector.getProtocolHandler() instanceof AbstractHttp11Protocol<?>)) {
//-1 for unlimited
((AbstractHttp11Protocol<?>) 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<?>)) {
//-1 for unlimited
((AbstractHttp11Protocol<?>) connector.getProtocolHandler()).setMaxSwallowSize(-1);
}
}
});
return tomcat;
}
Or in the Tomcat/conf/server.xml for 5MB
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxSwallowSize="5242880" />
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) -> {
if (container instanceof TomcatEmbeddedServletContainerFactory) {
TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
tomcat.addConnectorCustomizers(
(connector) -> {
connector.setMaxPostSize(10000000);//10MB
}
);
}
};
}
You can change the accepted size in the statement:
connector.setMaxPostSize(10000000);//10MB
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();
}
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.
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.
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;
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
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
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
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
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
These properties in spring boot application.properties makes the acceptable file size unlimited -
# To prevent maximum upload size limit exception
spring.servlet.multipart.max-file-size=-1
spring.servlet.multipart.max-request-size=-1
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.
put this in your application.yml file to allow uploads of files up to 900 MB
server:
servlet:
multipart:
enabled: true
max-file-size: 900000000 #900M
max-request-size: 900000000
In Spring Boot 2 the spring.http.multipart changed to spring.servlet.multipart
