The request gets passed over in the header information

1. Add HttpServletRequest annotations, may be passed as arguments

@Autowired
protected HttpServletRequest request;

2. Get header

/**
 * <h5>功能: 获取从request中传递过来的header信息</h5>
 * 
 * @return Map<String, Object>
 */
public Map<String, Object> getHeaders() {
    Map<String, Object> headerMap = new HashMap<String, Object>();
    Enumeration<?> er = request.getHeaderNames();//获取请求头的所有name值
    String headerName;
    while(er.hasMoreElements()){
        headerName = er.nextElement().toString();
        headerMap.put(headerName, request.getHeader(headerName));
    }

    return headerMap;
}

And can obtain information transfer over the request parameters in the composition of a complete tool class can also be inherited as a complete BaseService
