获取请求来源IP

方法一：hutool获取

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.5.8</version>
</dependency>

代码

String tagIp = ServletUtil.getClientIP(HttpServletRequest request);

方法二：自定义方法

public String getIpAddr(HttpServletRequest request) {
   
   
    final String UNKNOWN = "unknown";
    String ip = request.getHeader("X-Forwarded-For");
    if (StringUtils.isBlank(ip) || UNKNOWN.equalsIgnoreCase(ip)) {
   
   
        ip = request.getHeader("Proxy-Client-IP");
    }
    if (StringUtils.isBlank(ip) || UNKNOWN.equalsIgnoreCase(ip)) {
   
   
        ip = request.getHeader("WL-Proxy-Client-IP");
    }
    if (StringUtils.isBlank(ip) || UNKNOWN.equalsIgnoreCase(ip)) {
   
   
        ip = request.getHeader("HTTP_CLIENT_IP");
    }
    if (StringUtils.isBlank(ip) || UNKNOWN.equalsIgnoreCase(ip)) {
   
   
        ip = request.getHeader("HTTP_X_FORWARDED_FOR");
    }
    if (StringUtils.isBlank(ip) || UNKNOWN.equalsIgnoreCase(ip)) {
   
   
        ip = request.getRemoteAddr();
    }
    return ip;
