nginx代理，客戶端獲取ip為127.0.0.1處理方法

在nginx的配置文件中的location下添加

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

server {  
    listen 80;  
    server_name www.xxxx.com;  
    location / {  
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            
        client_max_body_size 2048m;  //設置文件上傳最大限制 2G
        proxy_pass http://localhost:8081;  
        index index.jsp index.html index.htm;  
        }  
} 

在java代碼里獲取ip地址修改為

public static String getip(HttpServletRequest request){
        String ip = request.getHeader("x-forwarded-for"); 
        System.out.println("x-forwarded-for ip: " + ip);
        if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {  
            // 多次反向代理后會有多個ip值，第一個ip才是真實ip
            if( ip.indexOf(",")!=-1 ){
                ip = ip.split(",")[0];
            }
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getHeader("Proxy-Client-IP");  
            System.out.println("Proxy-Client-IP ip: " + ip);
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getHeader("WL-Proxy-Client-IP");  
            System.out.println("WL-Proxy-Client-IP ip: " + ip);
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getHeader("HTTP_CLIENT_IP");  
            System.out.println("HTTP_CLIENT_IP ip: " + ip);
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getHeader("HTTP_X_FORWARDED_FOR");  
            System.out.println("HTTP_X_FORWARDED_FOR ip: " + ip);
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getHeader("X-Real-IP");  
            System.out.println("X-Real-IP ip: " + ip);
        }  
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {  
            ip = request.getRemoteAddr();  
            System.out.println("getRemoteAddr ip: " + ip);
        } 
        System.out.println("獲取客戶端ip: " + ip);
        return ip;  
    }
