I’m trying to set up a file upload feature using AngularJS on the front end and Spring MVC 3.0 as the backend. But I’m running into a 404 error when I try to access the upload form. Here’s what I’ve got so far:
My HTML file has a simple file input and an upload button. The AngularJS code manages the file selection and sends it to the server. I’ve configured a Spring Controller to process the file upload on the server side.
My JavaScript files are placed under WEB-INF/scripts, and the HTML pages are in WebContent/pages. Additionally, both spring-context.xml and web.xml are located in the WEB-INF folder.
When I use the URL http://localhost:9090/Test/api/userfile/fileUploadForm, I receive a 404 error. I suspect there might be an issue with the configuration or mapping, but I can’t figure out the problem.
Could someone help me identify the error? I’m new to AngularJS and Spring MVC, so any guidance would be appreciated. Thanks!
Hmm, intresting problem! have u checked if ur spring configuration is set up correctly? sometimes the component-scan can miss stuff. also, wat about ur angular routing? Maybe theres a mismatch there? Oh, and hav u tried using browser dev tools to see if the request is even reaching the server? Just curious, wat made u choose AngularJS for this project?
Having faced similar issues, I can suggest a few potential solutions. First, ensure your Spring MVC controller is properly annotated with @Controller and the correct @RequestMapping. Double-check that the URL in your AngularJS service matches the controller’s mapping. Also, verify that your web.xml has the correct servlet mappings for Spring’s DispatcherServlet.
Another common pitfall is incorrect file paths. Since your JavaScript files are in WEB-INF/scripts, make sure they’re properly referenced in your HTML. WEB-INF isn’t directly accessible, so you might need to adjust your file structure or use a resource handler in Spring configuration to serve these files.
Lastly, enable logging for Spring MVC to get more detailed error information. This can often reveal configuration issues or mismatched URLs that aren’t immediately apparent from the 404 error alone.
hey mate, had similar probs before. check ur controller annotations n make sure they match ur angular service URL. also, WEB-INF aint directly accessible - might wanna move those js files. try enabling spring mvc logging too, it helped me figure out weird 404s. good luck!
