我实现了扩展
HandlerInterceptorAdapter
preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
request.getReader();
IllegalStateException

public class LogRequest extends HttpServletRequestWrapper { public LogRequest(HttpServletRequest request) { super(request); } @Override public ServletInputStream getInputStream() throws IOException { //read from tmp file or string. } @Override public BufferedReader getReader() throws IOException { //read from tmp file or string } }缕嚏冻
及其子类的用法。 请注意，使用此解决方案时，仅在请求处理完成并且您的应用程序已读取请求正文之后，才会记录请求正文。烫珊
