How to get Client IP address in Spring bean
提问by
I have define a Spring bean.
我已经定义了一个 Spring bean。
<beans>
<bean id="remoteService" class="edu.wustl.catissuecore.CaTissueApplictionServicImpl" />
</beans>
Is there any way to get the IP address of client in this class? Similarly as available in the servlet request.getRemoteAddr();
有没有办法在这个类中获取客户端的IP地址？与在 servlet 中可用的类似request.getRemoteAddr()；

The simplest (and ugliest) approach is to use RequestContextHolder:
最简单（也是最丑陋）的方法是使用RequestContextHolder：
String remoteAddress = ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
.getRequest().getRemoteAddr();
Without knowing more about your bean and how it's wired up, that's the best I can suggest. If your bean is a controller (either subclassing AbstractControlleror being annotated with @Controller) then it should be able to get direct access to the request object.
在不了解您的 bean 及其连接方式的情况下，这是我能建议的最好方法。如果您的 bean 是控制器（子类化AbstractController或使用 注释@Controller），那么它应该能够直接访问请求对象。

Construct this:
构造这个：
@Autowired(required = true)
private HttpServletRequest request;
and use like this:
并像这样使用：
request.getRemoteAddr()

The best way to get client ip is to loop through the headers
获取客户端 ip 的最佳方法是遍历标头
private static final String[] IP_HEADER_CANDIDATES = {
"X-Forwarded-For",
"Proxy-Client-IP",
"WL-Proxy-Client-IP",
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_X_CLUSTER_CLIENT_IP",
"HTTP_CLIENT_IP",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"HTTP_VIA",
"REMOTE_ADDR" };
public static String getClientIpAddress(HttpServletRequest request) {
for (String header : IP_HEADER_CANDIDATES) {
String ip = request.getHeader(header);
if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {
return ip;
}
}
return request.getRemoteAddr();
}
