当使用 GET 方法调用服务时,它可以顺利运行,即打印request.getParameter(“userValue”)。
但在使用 Post 方法时,会为request.getParameter(“userValue”)打印 null

HTML code :( jsonObject有效json)

var myData = "userValue=" + jsonObject ;
     jQuery.ajax({
                  type: "POST",
                  url: "http://localhost:8080/Webservice_JS_26Oct/FieldsToFile/write",
                  data: myData,
                  contentType: "application/json; charset=utf-8",
                  dataType: "json",

Java代码:

    @RequestMapping(value = "/FieldsToFile")    
    public class FileWriter {

            @RequestMapping(value = "/write", method = RequestMethod.POST, produces = "application/json")

            public String getData(HttpServletRequest request) throws  IOException, IllegalStateException, ServletException {

                String jsonString = request.getParameter("userValue") ;
                System.out.println("jsonString = " + jsonString);
                String myData = request.getParameter("myData") ; 

我是新手,请告知如何使其适用于POST方法。

您可以使用request.getInputStream()打印请求正文部分。我建议您的contentType: "application/json; charset=utf-8",可以application/x-www-form-urlencodedHttpServletRequest request @Requestbody ..
