Java 如何在Aeron库中创建多目标强制转换

我正在尝试使用多目的地Cast传输，但我不知道如何配置它， 我试图实现使用和解释的示例URI

我有一个出版商和两个订户

在携带SimplePublisher.java和SimpleSubscriber.java的默认aeron参数中，我更改了：

来自SimplePublisher.java

final String channel = "aeron:udp?control=192.168.0.3:4050|control-mode=manual";

从SimpleSubscriber.java：

我复制了SimpleSubcriber1.java和SimpleSubcriber2.java类，并更改了以下配置：

SimpleSubcriber1：

final String channel = "aeron:udp?endpoint=192.168.0.4:4051"

及

SimpleSubcriber2：

final String channel = "aeron:udp?endpoint=192.168.0.5:4052"

发布者和订阅者的错误几乎相同：

对于出版商：

Publishing to aeron:udp?control=192.168.0.3:4050|control-mode=manual on stream Id 10

对于亚转录者：

Subscribing to aeron:udp?endpoint=192.168.0.4:4051 on stream Id 10

如果你需要，我可以给你更多的细节

PD：我让媒体驱动程序LowLatencyMediaDriver运行，这不是问题所在

提前感谢您

配置如下：

出版商：

Publishing to aeron:udp?control=192.168.0.3:4050|control-mode=manual on stream Id 10
io.aeron.exceptions.ChannelEndpointException: RuntimeException : Channel error: Cannot assign requested address: bind : aeron:udp?control=192.168.0.3:4050|control-mode=manual

aeron:udp？控制=：|控制模式=动态

订户：

aeron:udp？端点=：|控制=：|控制模式=动态

MDC的默认控制模式是动态的（可以省略）。每个订阅将通过控制通道注册自身，并随后在指定的端点上接收消息

另一种方法是使用“手动”控制模式，即出版物使用

addDestination

/

removedestation

手动添加订阅

至于你收到的错误：

无法分配请求的地址：bind:aeron:udp？endpoint=192.168.0.4:4051
在io.aeron.ClientConductor.onChannelEndpointError（ClientConductor.java:187）

您收到该消息的原因很可能是该端口上已存在侦听内容，或者该主机上不存在该接口
