Increase HTTP Post maxPostSize in Spring Boot

Question

I\'ve got a fairly simple Spring Boot web application, I have a single HTML page with a form with enctype=\"multipart/form-data\". I\'m getting this error:

Answer 1

The error here is not caused by max-file-size or max-request-size (as pointed out) but rather the container-specific max-http-post-size property. For tomcat (the default container), you can set:

server.tomcat.max-http-post-size: 10MB

Jetty:

server.jetty.max-http-post-size: 10MB

Undertow:

server.undertow.max-http-post-size: 10MB

This has the same effect as OP's answer here, but via application.properties which is much more preferable.

Answer 2

This worked for me with Tomcat 8

MBeanServer mbeanServer = ManagementFactory.getPlatformMBeanServer();
ObjectName objectName = new ObjectName("Catalina:type=Connector,port=" + 8080);
mbeanServer.setAttribute(objectName, new Attribute("maxPostSize", 100000000));

Answer 3

I do faced kind a similar issue. where I was getting -

 "IllegalStateException multi-part request contained parameter data (excluding uploaded files) that exceeded the limit for maxPostSize set on the associated connector"

Solution I have applied following property, where using max-http-form-post-size property did make the difference for me -

server:
  tomcat:
    max-http-form-post-size: 100000000
    max-swallow-size: 100000000

Along with -

spring:
  servlet:
    multipart:
      maxFileSize: 10MB
      maxRequestSize: 10MB

And it worked for me.

Answer 4

There is some difference when we define the properties in the application.yaml and application.properties.

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

Answer 5

Apply settings for Tomcat as well as servlet

You can set the max post size for Tomcat in application.properties which is set with an int as below. Just setting spring.servlet.multipart.max-request-size=10MB, as in some other answers, may not be enough.

# Web properties
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MB

# Server properties
server.tomcat.max-http-post-size=100000000
server.tomcat.max-swallow-size=100000000

Working with Spring Boot 2.0.5.RELEASE

Answer 6

None of the solutions did work for me and most of them are just downright offtopic because OP is talking about maxPostSize, and not maxFileSize (latter gives you a different error anyway if the size is exceeded)

Solution: in /tomcat/conf/server.xml add maxPostSize="" attribute to Connector

<!-- A "Connector" represents an endpoint by which requests are received
     and responses are returned. Documentation at :
     Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
     Java AJP  Connector: /docs/config/ajp.html
     APR (HTTP/AJP) Connector: /docs/apr.html
     Define a non-SSL/TLS HTTP/1.1 Connector on port 8080
-->
<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           maxPostSize="10485760"
           redirectPort="8443" />
