Question

我正试图以这种方式向netty端点发送消息：

new DefaultCamelContext().createProducerTemplate().sendBody("netty:tcp://localhost:5150", "dummy");

我收到了错误：

这个错误究竟是什么？我怎么能解决这个问题呢？我已经阅读了this次讨论，但我找不到答案。

NettyComponent只是在启动时设置计时器。所以你需要首先启动camel上下文，这样CamelContext可以默认启动组件。

 CamelContext context = new DefaultCamelContext();
 context.start();
 context.createProducerTemplate().sendBody("netty:tcp://localhost:5150", "dummy");

必须指定Camel netty计时器错误
