Question

我正在尝试从嵌入式码头服务器记录请求正文。

我成功获取了POST请求的正文（主要来自https://stackoverflow.com/a/19547549/8916463和https://stackoverflow.com/a/8972088/8916463）

public class JettyFilter {

  public static void main(final String[] args) throws Exception {
    Server server = new Server(8080);

    ServletHandler handler = new ServletHandler();
    server.setHandler(handler);

    handler.addServletWithMapping(HelloServlet.class, "/*");
    handler.addFilterWithMapping(WebServerLoggingFilter .class, "/*",
        EnumSet.of(DispatcherType.REQUEST));

    server.start();
    server.join();
  }

  public static class HelloServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)  throws ServletException, IOException { 
            System.out.println(request.getReader().lines()
                    .collect(Collectors.joining(System.lineSeparator())));
    }
  }

public static class WebServerLoggingFilter implements Filter {

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

        System.out.println("hello from filter");
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

    @Override
    public void destroy() {}
  }
}

问题在于，当我以此方式配置服务器时，根本不会调用来自控制器的POST请求。但是当我尝试使用NCSA日志记录（在这种情况下未记录请求正文）时，会正确调用它们：

NCSARequestLog requestLog = new NCSARequestLog(os.getDatedFilename());
requestLog.setExtended(true);
RequestLogHandler requestLogHandler = new RequestLogHandler();
requestLogHandler.setRequestLog(requestLog);
requestLog.setAppend(true);

HandlerList mainHandlers = new HandlerList();
mainHandlers.addHandler(accessHandler);
mainHandlers.addHandler(new DefaultHandler());

requestLogHandler.setHandler(mainHandlers);
HandlerList topLevelHandlers = new HandlerList();
topLevelHandlers.addHandler(requestLogHandler);

server.setHandler(topLevelHandlers);

我的目标是将请求正文记录到某个文件中。

显然，我错过了一些非常简单的事情，并且可以更轻松地实现请求正文的记录。

PS。没有使用弹簧。

任何帮助将不胜感激！
