java webservice服务器端获取request对象的三种方式

有的时候在webservice里我们需要获取request对象和response对象，比如想要获得客户端的访问ip的时候就需要这么做，下面说三种方式，当然三种方式可能是针对不同方式部署webservice获取request对象的方法。

第一种:先配置注入:

@Resource
private WebServiceContext webServiceContext;

其次是下面的代码:

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

第二种:

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

第三种(附带获取客户端ip地址的方法):

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

获取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;
    }
