--------------------------------------

             Summary: camel-servlet doesn't support multipart requests.
                 Key: CAMEL-16950
                 URL: https://issues.apache.org/jira/browse/CAMEL-16950
             Project: Camel
          Issue Type: Bug
    Affects Versions: 3.11.0
            Reporter: Avinash Dongre


[This|https://gist.github.com/avi5kdonrh/1ff3cc0e1af84e1c2c162ffe1b3852d3] test results in the following error.
{code:java}
java.lang.IllegalStateException: UT010057: multipart config was not present on Servlet

The only workaround here is to disable  auto configuration:

camel.component.servlet.mapping.enabled=false

And create a custom servlet auto configuration class:
{code:java}
@Configuration
@EnableConfigurationProperties(ServletMappingConfiguration.class)
public class CustomAutoConfiguration {

    @Bean
    ServletRegistrationBean servletRegistrationBean(ServletMappingConfiguration config) {
        ServletRegistrationBean mapping = new ServletRegistrationBean();
        mapping.setServlet(new CamelHttpTransportServlet());
        mapping.addUrlMappings(config.getContextPath());
        mapping.setName(config.getServletName());
        mapping.setLoadOnStartup(1);
        mapping.setMultipartConfig(new MultipartConfigElement("/tmp"));

        return mapping;
    }

}

{code}
