我已经定义了一个Spring bean。
<beans>
<bean id="remoteService" class="edu.wustl.catissuecore.CaTissueApplictionServicImpl" />
</beans>
有没有办法在这个课程中获取客户端的IP地址?与servlet request.getRemoteAddr()
中的可用类似;

最简单(也是最丑陋)的方法是使用RequestContextHolder
:
String remoteAddress = ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
.getRequest().getRemoteAddr();
如果不了解更多关于你的bean以及它是如何接线的,那就是我能建议的最好的。如果你的bean是一个控制器(子类化AbstractController
或用@Controller
注释),那么它应该能够直接访问请求对象。

获取客户端IP的最佳方法是遍历标题
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();
}

构造这个:
@Autowired(required = true)
private HttpServletRequest request;
并使用如下:
request.getRemoteAddr()
