问题 This question already has answers here : Can I turn off the HttpSession in web.xml? (9 answers) Closed 3 years ago . I would like to know if it is possible to disable the HTTPSession for an application server handling only web services RESTful . I don't know if there are specific application servers or servlet containers designed to handle micro RESTful web services. I think that disabling completely the session concept will give the following advantages: Better performances No risk to save

问题 Code i used to convert my reg_be obj to is inputstream. ByteArrayOutputStream baos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(reg_be); oos.flush(); oos.close(); InputStream is = new ByteArrayInputStream(baos.toByteArray()); Then i pass this inputstream to webservice.

问题 I'm building a RESTful API, using spring-hateoas library to implement hypermedia. The response of my endpoints is application/hal+json (My DTO extends ResourceSupport). I'm using Swagger to document the endpoints, and using Springfox to autogenerate the swagger-ui. The problem is, that the generated documentation is not correct. As a request for a POST endpoint, the UI is setting the _links section from my DTO as part of the payload, so this is what I see I should send as a parameter for my

问题 I am wondering what is the best design approach between using a big state (store) and sql request in database. Let's say you have a Todo CRUD application. You can save the Todos list in store within Redux implementation. What is the best approach if you want to make complex statistics on those TODOs: Reducers or sql requests? For example, you want to get all todos for the current month: Reducers/store approach You can get all the todos list from the store and filter todos by date to get all

问题 I have the following entity: <car> <carID>7</carID> <...>...</...> <externalCarID>23890212</externalCarID> </car> The problem is now that carID and externalCarID are both independent primary keys that are used by/for different systems and it should be possible for API clients to access a car entity with both the carID xor the externalCarID . Both keys are ints and they do not use disjoint sets: carID(7) != externalCarID(7) I have thought of the following solutions: Access it with /restapi/car

问题 Im trying to send a local file by client curl app. I found some examples to do that with files from a form. In my case, I have no form, but a local file. $fileName = $_SERVER["DOCUMENT_ROOT"]."/www/images/test.pdf"; if(!file_exists($fileName)) { $out['status'] = 'error'; $out['message'] = 'File not found.'; exit(json_encode($out)); } $data = array('name' => 'Foo', 'file' => '@'.$fileName); $cURL = curl_init("http://myapi/upload-images"); curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true); curl

问题 I have a server endpoint which validates some data and return true/false if the data validation has no errors. So which Version would be correct or more suitable for a RESTful webservice? POST https://server.de/validate POST data in body and return HTTP status code 200 if validation had no errors or GET https://server.de/validate?=data Send data in header or query parameter and return true/false in the response (Status code 200 would be returned after a correct request, independent of the

问题 I need to send the request XML file to {url} as multipart form data. How this do in Restful web service. Before I use in there in, RequestDispatcher rd = request.getRequestDispatcher("/file/message.jsp"); rd.forward(request, response); But this isn't sent in specific {url}, How to sent it? 回答1: You can use the Jersey Rest Client to send your XML message as post request . try { Client client = Client.create(); WebResource webResource = client.resource(http://<your URI>); // POST method
