獲取request中傳遞過來的header信息

1.添加HttpServletRequest註解,也能夠做爲參數傳遞

@Autowired
protected HttpServletRequest request;

2.獲取header

/**
 * <h5>功能: 獲取從request中傳遞過來的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();//獲取請求頭的全部name值
    String headerName;
    while(er.hasMoreElements()){
        headerName = er.nextElement().toString();
        headerMap.put(headerName, request.getHeader(headerName));
    }

    return headerMap;
}

能夠和獲取request中傳遞過來的參數信息組成一個完整的工具類,也能夠做爲一個完整BaseService被繼承
