java获取项目所在服务器的ip地址和端口号（获取当前ip地址）

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;
	}
