Description

This test results in the following error.

java.lang.IllegalStateException: UT010057: multipart config was not present on Servlet
	at io.undertow.servlet.spec.HttpServletRequestImpl.verifyMultipartServlet(HttpServletRequestImpl.java:541)
	at io.undertow.servlet.spec.HttpServletRequestImpl.getPart(HttpServletRequestImpl.java:547)

The only workaround here is to disable  auto configuration:

camel.component.servlet.mapping.enabled=false

And create a custom servlet auto configuration class:

@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;
    }

}
