我想将数据从servlet发送到rest api.
它是如何完成的：
protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException {String Id= "MyId";response.setContentType("application/json");response.getWriter().write(Id);getServletContext().getRequestDispatcher("<PathofAPI>").forward(request,response);}
数据发送后,如何在我的剩余api中检索数据
最佳答案
或者,您必须使用getter和setter为您的Id参数创建POJO类：
String createRequestUrl="YOUR_LINK WHERE_YOU GET answer FROM";RestTemplate template=new RestTemplate();your_POJO_object.setYour_Pojo_Object(Id);ObjectMapper objectMapper = new ObjectMapper();MultiValueMap<String,String> orderRequestHeaders=newLinkedMultiValueMap<String,String>();orderRequestHeaders.add("Content-Type","application/json");orderRequestHeaders.add("Accept","application/json");String orderCreateRequest=objectMapper.writeValueAsString(YOUR POJO object.class);HttpEntity<String> orderRequest=new HttpEntity<String>(orderCreateRequest,orderRequestHeaders);String response=template.postForObject(createRequestUrl,orderRequest,String.class);
