您可以添加这些方法。在
TransportContextHolder将持有线程局部变量（在这种情况下HTTP）与交通有关的一些数据。您可以
HttpServletRequest从访问
TransportContext。
protected HttpServletRequest getHttpServletRequest() { TransportContext ctx = TransportContextHolder.getTransportContext(); return ( null != ctx ) ? ((HttpServletConnection ) ctx.getConnection()).getHttpServletRequest() : null;}protected String getHttpHeaderValue( final String headerName ) { HttpServletRequest httpServletRequest = getHttpServletRequest(); return ( null != httpServletRequest ) ? httpServletRequest.getHeader( headerName ) : null;}
