Uploading File Returns 403 Error - Spring MVC

Question

In my Spring MVC project I am trying to upload a file via a simple form.

HTML Form:

Answer 1

For me even with the csrf().disable() its didn't work. Once i disable it i got 200 but the file wasn't uploaded and i didn't see any error. Once i set the debug flag logging.level.org.springframework.web: DEBUG i saw the root cause:

[org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location [/target/tomcat/work/Tomcat/localhost/ROOT] is not valid]","exception":""}

I tried setting the location on application.yaml: spring.servlet.http.multipart.location: "/tmp" but it didn't change the location so what i did is adding the below code and it did the trick:

@Bean

MultipartConfigElement multipartConfigElement() {
    MultipartConfigFactory factory = new MultipartConfigFactory();
    String location = "/tmp";
    LOGGER.debug("Multipart location file:" + location);
    File tmpFile = new File(location);
    if (!tmpFile.exists()) {
        tmpFile.mkdirs();
    }
    factory.setLocation(location);
    return factory.createMultipartConfig();
}
