Http连接池在重新启动Camel上下文时关闭

camel-http4 . 基本上,在上下文启动时,该路由每5分钟向外部服务器发出一个http请求。这工作非常好。

在某个时候,我想重新启动camel上下文(使用JMX),所以我只需要:

if (camelContext.getStatus().isStoppable()) {
  camelContext.stop();
}

后来:

if (camelContext.getStatus().isStarttable()) {
  camelContext.start();
}

两个操作似乎都成功了,日志确认了实际的停止和启动。但是当发出第一个http请求时,我得到以下错误:

java.lang.IllegalStateException: Connection pool shut down

连接池似乎处于无效状态。 如何在启动上下文时强制重新创建池?

我已经看到一些帖子说连接管理器必须通过使用HttpClientConfigurer(这更像是一个解决方法)来共享。 我定义并注入了自己的客户端配置程序,但它不起作用:

public class MyHttpClientConfigurer implements HttpClientConfigurer {

    @Override
    public void configureHttpClient(HttpClientBuilder httpClientBuilder) {
        httpClientBuilder.setConnectionManagerShared(true);
    }
}
