## 不传参数，直接通过ServletRequestAttributes获取当前项目所在服务器的端口号和ip地址 ##

public static String getUrl(){
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        String localAddr = request.getLocalAddr();
        int serverPort = request.getServerPort();
        return "http://"+localAddr +":"+ serverPort;
    }

## 通过 HttpServletRequest 传参数获取当前项目所在服务器的端口号和ip地址 ##

//获取本地服务器的ip地址和端口号
        public static String getHttpUrl(HttpServletRequest request){
            String localAddr = request.getLocalAddr();
            int serverPort = request.getServerPort();
            return "http://"+localAddr +":"+ serverPort;
        }

## Java获取当前系统的ip地址，端口号从配置文件读取 ##

@Value("${server.port}")
    private int serverPort;
    
    public String getUrl() {
        InetAddress address = null;
        try {
            address = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        return "http://"+address.getHostAddress() +":"+this.serverPort;
    }

## tomcat服务器启动到时候获取服务器的ip和端口号，本方法在windows系统没问题，再Linux系统就不行了       //获取本地服务器的ip地址和端口号 ##

public static String getUrl() {
            String serverIp = "";
            String serverPort = "";
            try {
                MBeanServer beanServer = ManagementFactory.getPlatformMBeanServer();
                Set<ObjectName> objectNames = beanServer.queryNames(new ObjectName("*:type=Connector,*"), 
                Query.match(Query.attr("protocol"), Query.value("HTTP/1.1")));
                serverIp = InetAddress.getLocalHost().getHostAddress();
                serverPort = objectNames.iterator().next().getKeyProperty("port");
            } catch (Exception e) {
                e.printStackTrace();
            }
            String ipAndPost = "http://" + serverIp + serverPort;
            return ipAndPost;
        }

获取服务器的ip+端口号

public static String PathAddress() {
    		String strResult = "";
    		HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
    				.getRequestAttributes()).getRequest();
    
    		StringBuffer strBuf = new StringBuffer();
    		strBuf.append(request.getScheme() + "://");
    		strBuf.append(request.getServerName() + ":");
    		strBuf.append(request.getServerPort() + "");
    		strBuf.append(request.getContextPath() + "/");
    		strResult = strBuf.toString();// +"FHADMINM/";//加入项目的名称
    		return strResult;
    	}
