java webservice服務器端獲取request對象的三種方式

有的時候在webservice里我們需要獲取request對象和response對象，比如想要獲得客戶端的訪問ip的時候就需要這么做，下面說三種方式，當然三種方式可能是針對不同方式部署webservice獲取request對象的方法。

第一種:先配置注入:

@Resource
private WebServiceContext webServiceContext;

其次是下面的代碼:

MessageContext mc = webServiceContext.getMessageContext();
HttpServletRequest request = (HttpServletRequest) (mc.get(MessageContext.SERVLET_REQUEST));

第二種:

WebServiceContext context = new WebServiceContextImpl();
MessageContext ctx = context.getMessageContext();
HttpServletRequest request = (HttpServletRequest) ctx.get(AbstractHTTPDestination.HTTP_REQUEST);

第三種(附帶獲取客戶端ip地址的方法):

Message message = PhaseInterceptorChain.getCurrentMessage();
HttpServletRequest request = (HttpServletRequest) message.get(AbstractHTTPDestination.HTTP_REQUEST);

獲取ip:

public static String getIpAddr(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for");
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getHeader("Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || "unknow".equalsIgnoreCase(ip)) {
            ip = request.getHeader("WL-Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getRemoteAddr();
        }
        return ip;
    }
