Answer 1

Since @SeaBiscuit has provided the correct answer but with Spring boot 2.0.0.RELEASE the class org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory has been removed and replaced by the class org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory. So the code for the new Spring boot 2.0.0 would be

1. Create a class with any name and annotate it with @Configuration
2. And put the below code inside that class

@Bean
public TomcatServletWebServerFactory containerFactory() {
    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
    factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
        @Override
        public void customize(Connector connector) {
            ((AbstractHttp11Protocol) connector.getProtocolHandler()).setMaxSwallowSize(-1);
        }
    });
    return factory;
}

And if you've trouble configuring the maximum file upload size in Spring boot 2.0.0 put below code inside 'application.propertise' file with desired file size in 'MB's

## Image upload limitation properties
spring.servlet.multipart.max-file-size=3MB
spring.servlet.multipart.max-request-size=3MB
