java获取当前项目的ip和端口号

各位大佬不好意思，最近有点忙好久没更新了，今天来一篇就是我们常用的项目的ip和端口号的动态获取
ip动态获取：

public class IpUtil {
    public static String getRemortIp(HttpServletRequest request){
        if(request.getHeader("x-forwarded-for") == null){
            return request.getRemoteAddr();
        }
        return request.getHeader("x-forwarded-for");
    }
}

这里要注意下如果项目在我们本地的话这里获取到的IP为：

0:0:0:0:0:0:0:1

解决方法见下面链接：

个人建议如果在本地的话可以就直接设置成localhost,服务器上会获取得到特别在支付这一块用的比较多

端口动态获取：

public class PortUtil {
    public static String getLocalPort() throws Exception {
        MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
        Set<ObjectName> objectNames = mBeanServer.queryNames(new ObjectName("*:type=Connector,*"), null);
        if (objectNames == null || objectNames.size() <= 0) {
            throw new IllegalStateException("Cannot get the names of MBeans controlled by the MBean server.");
        }
        for (ObjectName objectName : objectNames) {
            String protocol = String.valueOf(mBeanServer.getAttribute(objectName, "protocol"));
            String port = String.valueOf(mBeanServer.getAttribute(objectName, "port"));
            // windows下属性名称为HTTP/1.1, linux下为org.apache.coyote.http11.Http11NioProtocol
            if (protocol.equals("HTTP/1.1") || protocol.equals("org.apache.coyote.http11.Http11NioProtocol")) {
                return port;
            }
        }
        throw new IllegalStateException("Failed to get the HTTP port of the current server");
    }

}

这里要注意区分下windows和linux系统中的protocol区别。
