Feign拦截器
通过实现RequestInterceptor接口来实现Feign的拦截器，实现apply方法
public class FeignRequestInterceptor implements RequestInterceptor
{
@Override
public void apply(RequestTemplate requestTemplate)
{
HttpServletRequest request = ((ServletRequestAttributes) (RequestContextHolder.currentRequestAttributes())).getRequest();
if (StringUtils.isNotNull(httpServletRequest))
{
Map<String, String> headers = ServletUtils.getHeaders(httpServletRequest);
// 传递用户信息请求头，防止丢失
String userId = headers.get("userId");
if (StringUtils.isNotEmpty(userId))
{
requestTemplate.header("userId", userId);
}
String userName = headers.get("userName");
if (StringUtils.isNotEmpty(userName))
{
requestTemplate.header("userName", userName);
}
String authentication = headers.get("authentication");
if (StringUtils.isNotEmpty(authentication))
{
requestTemplate.header("authentication", authentication);
}
// 配置客户端IP
requestTemplate.header("X-Forwarded-For", IpUtils.getIpAddr(ServletUtils.getRequest()));
}
}
}
