获取request中传递过来的header信息

1.添加HttpServletRequest注解,也能够做为参数传递

@Autowired
protected HttpServletRequest request;

2.获取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();//获取请求头的全部name值
    String headerName;
    while(er.hasMoreElements()){
        headerName = er.nextElement().toString();
        headerMap.put(headerName, request.getHeader(headerName));
    }

    return headerMap;
}

能够和获取request中传递过来的参数信息组成一个完整的工具类,也能够做为一个完整BaseService被继承
