There are several methods for cross-origin uploading files in Java:<\/p>\n

    \n
  1. Utilize the FormData object in HTML5: Upload files in the frontend using the FormData object in HTML5, then send the file data to the backend through Ajax. Handle cross-domain requests in the backend using CORS (Cross-Origin Resource Sharing).<\/li>\n
  2. Using Flash plugin: Use Flash plugin in the front end to achieve file uploading. Flash can upload files cross-domain and communicate with the backend. Use CORS in the backend to handle cross-domain requests.<\/li>\n
  3. Utilizing a proxy server: Upload files to a proxy server within the same domain at the frontend, then transfer them to the target server. This can help prevent issues with cross-origin file uploads.<\/li>\n
  4. Utilize JSONP: Convert file data to Base64 encoding in the frontend, then transmit it across domains to the backend using JSONP. Decode the Base64 encoding back into a file in the backend.<\/li>\n<\/ol>\n

    It should be noted that all of the above methods require corresponding processing on the backend, such as setting CORS, parsing file data, etc. The specific implementation can be chosen based on specific needs and technology stack.<\/p>\n","protected":false},"excerpt":{"rendered":"
