1.网关添加过滤器：
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Component;
import com.netflix.zuul.ZuulFilter;
import com.netflix.zuul.context.RequestContext;
@Component
public class XForwardedForFilter extends ZuulFilter {
private static final String HTTP_X_FORWARDED_FOR = "HTTP_X_FORWARDED_FOR";
@Override
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
HttpServletRequest request = ctx.getRequest();
String remoteAddr = request.getRemoteAddr();
ctx.getZuulRequestHeaders().put(HTTP_X_FORWARDED_FOR, remoteAddr);
return null;
}
@Override
public boolean shouldFilter() {
return true;
}
@Override
public String filterType() {
return "pre";
}
@Override
public int filterOrder() {
return 0;
}
}
2.微服务获取ip:
String ip = request.getHeader("HTTP_X_FORWARDED_FOR");
