我使用J2EE 1.4 创建了 JAX-RPC Web服务。当我尝试从Web服务获取客户端IP地址时，它始终将 IP设为127.0.0.1 < / strong>即可。 请解决我的问题。
服务实施类：
public class LeaveDetailsServiceImpl implements ServiceLifecycle {
private javax.xml.rpc.server.ServletEndpointContext ctx;
public void init(Object arg0) throws ServiceException {
ctx=(javax.xml.rpc.server.ServletEndpointContext)arg0;
}
public String getLeaveDetails(String empCode,String leaveYear,String uname,String pwd) throws RemoteException {
StringBuffer resultMessage=new StringBuffer();
String finalResult="";
EmployeeWorker empWorker=new EmployeeWorker();
HttpServletRequest request = (HttpServletRequest) ctx.getMessageContext().getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);
String clientIpAddress = request.getHeader("X-FORWARDED-FOR");
if (clientIpAddress == null) {
clientIpAddress = request.getRemoteAddr();
}
//LeaveDetailsForm leaveDetails=new LeaveDetailsForm();
try
{
if(ServiceUtil.authenticate(uname,pwd,clientIpAddress))
{
if(empCode.trim()==null || empCode.trim().length()==0 || empCode.trim().equals(""))
{
resultMessage.append("Emp Code is required<br/>");
}
if(leaveYear.trim()==null || leaveYear.trim().length()==0 || leaveYear.trim().equals(""))
{
resultMessage.append("Leave Year is required<br/>");
}
if(!empCode.trim().matches("^\\d+$"))
{
resultMessage.append("Emp Code should have digits only<br/>");
}
else
{
if(!empWorker.checkEmpCode(empCode))
{
resultMessage.append("Employee Code does not exist<br/>");
}
}
if(!leaveYear.trim().matches("^\\d{4}$"))
{
resultMessage.append("Leave Year should have exactly 4 digits<br/>");
}
else if(Integer.parseInt(leaveYear.trim())<2006)
{
resultMessage.append("Leave Year can not be before 2006<br/>");
}
else if(Integer.parseInt(leaveYear.trim())>=Calendar.getInstance().get(Calendar.YEAR))
{
resultMessage.append("Leave Year can not be a future year<br/>");
}
finalResult=resultMessage.toString();
if(finalResult.equals(""))
{
ServiceUtil sUtil=new ServiceUtil();
finalResult=sUtil.getServiceWaitTime();
if(finalResult.equals("ok"))
{
//aLeaveDetails=
finalResult=empWorker.getLeaveDetails(empCode,leaveYear);
if(finalResult.indexOf("<Leave>") ==-1)
{
finalResult="Employee has no leave record for the year "+leaveYear;
}
}
}
}
else
{
finalResult="You are not a authorized user";
}
}
catch(Exception ex){
System.out.println( ex.getMessage());
}
return finalResult;
}
public void destroy() {
// TODO Auto-generated method stub
}
}
过滤类：
public class ClientIPAddressFilter implements Filter {
public ClientIPAddressFilter() {
super();
}
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
System.out.println("Remote Address: "+request.getRemoteAddr());
chain.doFilter(request, response);
}
public void destroy() {
// TODO Auto-generated method stub
}
}
