遇到个问题，自己定义了个feign拦截器，把前端header里的参数全部转发到下游，本地运行一切正常，上了服务之后就开始报错。
@Component
@Slf4j
public class FeignHeaderInterceptor implements RequestInterceptor {
@Override
public void apply(RequestTemplate requestTemplate) {
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
if (attributes!=null) {
HttpServletRequest request = attributes.getRequest();
Enumeration<String> headerNames = request.getHeaderNames();
if (headerNames != null) {
while (headerNames.hasMoreElements()) {
String name = headerNames.nextElement();
String values = request.getHeader(name);
log.info("key is{},value is{}",name,values);
requestTemplate.header(name, values);
}
}
}
}
}
配置如下：
@Configuration
@Component
@Slf4j
public class CustomFeignBuilder {
@Bean(name = "custom")
public Feign.Builder getFeignBuilder() {
return Feign.builder()
.logLevel(Level.NONE)
.encoder(new JacksonEncoder())
.decoder(new JacksonDecoder())
.logger(new ErrorLogger())
.errorDecoder(errorDecoder())
.options(getOptions())
.requestInterceptor(new FeignHeaderInterceptor())
.client(apacheHttpClient());
}
// @Bean
// public OkHttpClient getOkHttpClient() {
// Builder builder = new Builder();
// builder.connectTimeout(200, TimeUnit.MILLISECONDS);
// builder.readTimeout(1, TimeUnit.SECONDS);
// builder.writeTimeout(1, TimeUnit.SECONDS);
// builder.followRedirects(true);
// builder.connectionPool(new ConnectionPool(120, 5, TimeUnit.MINUTES));
//// builder.dispatcher(new Dispatcher( new ThreadPoolExecutor(1000, 2000, 60, TimeUnit.SECONDS,
//// new SynchronousQueue<Runnable>(), Util.threadFactory("OkHttp Dispatcher", false))));
// okhttp3.OkHttpClient okHttpClient = builder.build();
// okHttpClient.dispatcher().setMaxRequestsPerHost(80);
// okHttpClient.dispatcher().setMaxRequests(120);
// return new OkHttpClient(okHttpClient);
// }
@Bean
public FeignErrorDecoder errorDecoder() {
return new FeignErrorDecoder();
}
@Bean
public Request.Options getOptions() {
return new Request.Options(2, TimeUnit.SECONDS, 2, TimeUnit.SECONDS, true);
}
@Bean
public ApacheHttpClient apacheHttpClient(){
log.info("init feign httpclient configuration " );
// 生成默认请求配置
RequestConfig.Builder requestConfigBuilder = RequestConfig.custom();
// 超时时间
requestConfigBuilder.setSocketTimeout(2* 1000);
// 连接时间
requestConfigBuilder.setConnectTimeout(2* 1000);
// 连接池获取的 超时时间
requestConfigBuilder.setConnectionRequestTimeout(2*1000);
RequestConfig defaultRequestConfig = requestConfigBuilder.build();
// 连接池配置
// 长连接保持30秒
final PoolingHttpClientConnectionManager pollingConnectionManager = new PoolingHttpClientConnectionManager(30, TimeUnit.MILLISECONDS);
// 总连接数
pollingConnectionManager.setMaxTotal(5000);
// 同路由的并发数
pollingConnectionManager.setDefaultMaxPerRoute(1000);
// httpclient 配置
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
// 保持长连接配置，需要在头添加Keep-Alive
httpClientBuilder.setKeepAliveStrategy(new DefaultConnectionKeepAliveStrategy());
httpClientBuilder.setConnectionManager(pollingConnectionManager);
httpClientBuilder.setDefaultRequestConfig(defaultRequestConfig);
CloseableHttpClient client = httpClientBuilder.build();
// 启动定时器，定时回收过期的连接
ScheduledExecutorService scheduledExecutorService = Executors.newSingleThreadScheduledExecutor();
scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
log.debug("=====closeIdleConnections===");
pollingConnectionManager.closeExpiredConnections();
pollingConnectionManager.closeIdleConnections(5, TimeUnit.SECONDS);
}
}, 10 * 1000, 5 * 1000, TimeUnit.MILLISECONDS);
log.info("===== Apache httpclient 初始化连接池===");
return new ApacheHttpClient(client);
}
}
上了服务之后报错信息如下：

实在是不知道哪里有问题，本地调试完全正常，求各位解答
