Spring Boot小技巧总结

Feign客户端直接指定IP调用服务

@FeignClient(value = "appblog-provider-channel-core", url="192.168.1.10:8888")
public interface ChannelPayApi extends IChannelPayApi {

}

获取请求Header

public Result<Response> query(@PathVariable("id") String id, @RequestHeader("token") String token) {

}

RequestContext请求上下文设置与获取

public class GatewayPreFilter extends ZuulFilter {

    @Override
    public Object run() throws ZuulException {
        RequestContext.getCurrentContext().set(String key, Object value);

public class GatewayPostFilter extends ZuulFilter {

    @Override
    public Object run() throws ZuulException {
        RequestContext requestContext = RequestContext.getCurrentContext();
        Object value = (String) requestContext.get(String key);
