SpringMVC怎样获取客户端的ip地址

SpringMVC怎样获取客户端的ip地址

在spring框架管理下，你可以在任意一个spring管理的bean中使用 @Autowired注解来注入一个 HttpServletRequest，然后就可以从请求头中获取ip地址了。

示例代码如下：

@Componentpublic class WebUtils {    private HttpServletRequest request;    @Autowired    public void setRequest(HttpServletRequest request) {        this.request = request;    }    private static String getClientIp() {        String remoteAddr = "";        if (request != null) {            remoteAddr = request.getHeader("X-FORWARDED-FOR");            if (remoteAddr == null || "".equals(remoteAddr)) {                remoteAddr = request.getRemoteAddr();            }        }        return remoteAddr;    }}
