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：
原文链接：https://www.f2er.com/java/532899.htmlString 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=new
LinkedMultiValueMap<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);
