[SPRING] HttpServletRequest에서 XML 가져 오기 및 끝점에 사용

HttpServletRequest에서 XML 가져 오기 및 끝점에 사용

요청 및 응답에서 XML 데이터를 가져와 Rest 컨트롤러에 사용하고 싶습니다. 나는 이것을 시도 :

@RestController()
    public class HomeController {

        @PostMapping(value = "/v1")
      public Response handleMessage(@RequestBody Transaction transaction, HttpServletRequest request, HttpServletResponse response) throws Exception {

           HttpServletRequest request, HttpServletResponse response

            System.out.println("!!!!!!! InputStream");
            System.out.println(request.getInputStream());
            System.out.println(response.getOutputStream());

            InputStream in = request.getInputStream();
            String readLine;
            BufferedReader br = new BufferedReader(new InputStreamReader(in));

            while (((readLine = br.readLine()) != null)) {
                System.out.println(readLine);    
            }
         } 
    }

하지만 java.io.IOException 얻을 : UT010029 : 스트림 닫힙니다.

문자열 변수에 내용을 가져 오는 적절한 방법은 무엇입니까?

편집 : 나는 또한 필터를 사용하여 솔루션을 시도했지만 나머지 컨트롤러에 요청 페이로드를 사용하는 방법을 알지 못합니다.

읽기 요청 페이로드 :

@Component
public class HttpLoggingFilter implements Filter {

    private static final Logger logger = LoggerFactory.getLogger(HttpLoggingFilter.class);

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

        ResettableStreamHttpServletRequest wrappedRequest = new ResettableStreamHttpServletRequest((HttpServletRequest) request);
        wrappedRequest.getInputStream().read();
        String body = IOUtils.toString(wrappedRequest.getReader());
        System.out.println("!!!!!!!!!!!!!!!!!! " + body);
        wrappedRequest.resetInputStream();


        chain.doFilter(request, response);
    }

    public class ResettableStreamHttpServletRequest extends HttpServletRequestWrapper {
        private byte[] rawData;
        private HttpServletRequest request;
        private ResettableServletInputStream servletStream;

        ResettableStreamHttpServletRequest(HttpServletRequest request) {
            super(request);
            this.request = request;
            this.servletStream = new ResettableServletInputStream();
        }

        void resetInputStream() {
            servletStream.stream = new ByteArrayInputStream(rawData);
        }

        @Override
        public ServletInputStream getInputStream() throws IOException {
            if (rawData == null) {
                rawData = IOUtils.toByteArray(this.request.getInputStream());
                servletStream.stream = new ByteArrayInputStream(rawData);
            }
            return servletStream;
        }

        @Override
        public BufferedReader getReader() throws IOException {
            if (rawData == null) {
                rawData = IOUtils.toByteArray(this.request.getInputStream());
                servletStream.stream = new ByteArrayInputStream(rawData);
            }
            String encoding = getCharacterEncoding();
            if (encoding != null) {
                return new BufferedReader(new InputStreamReader(servletStream, encoding));
            } else {
                return new BufferedReader(new InputStreamReader(servletStream));
            }
        }

        private class ResettableServletInputStream extends ServletInputStream {
            private InputStream stream;

            @Override
            public int read() throws IOException {
                return stream.read();
            }

            @Override
            public boolean isFinished() {
                // TODO Auto-generated method stub
                return false;
            }

            @Override
            public boolean isReady() {
                // TODO Auto-generated method stub
                return false;
            }

            @Override
            public void setReadListener(ReadListener readListener) {
                // TODO Auto-generated method stub

            }
        }
    }   
}

나머지 끝점 :

@RestController()
public class HomeController {

    @PostMapping(value = "/v1")
  public Response handleMessage(@RequestBody Transaction transaction, HttpServletRequest request, org.zalando.logbook.HttpRequest requestv, HttpServletResponse response) throws Exception {

       // Get here request and response and log it into DB
     } 
}

HttpLoggingFilter를 Java 메소드 handleMessage에 호출하여 본문 문자열로 요청을받을 수있는 방법은 무엇입니까? 아마 내가 서비스하고 주사 할 수 있을까? 코드를 평가할 수있는 조언을 해줄 수 있습니까?
