我正在开发 Spring Boot + Axon + CQRS 示例。在此示例中，点击
curl -H“ Content-Type：application / json” -d'{“ company”：“ apple”，“ description”：“ My Kep”}'http://localhost:8080
我已经启动了以下服务器（axonserver-4.0.jar），但看不到解决错误的方法。如果您需要其他详细信息，请告诉我？

答案 0 :(得分：3)
错误The command [...] does not contain a routing key是由命令中缺少带注释的字段@TargetAggregateIdentifier引起的。在轴突LocalCommandBus中，仅在针对现有集合的命令上才需要这样做。在分布式版本中，创建Agregaton的命令也是必须的，因为Axon Server命令总线会查看它以做出路由决策。
因此，将@TargetAggregateIdentifier添加到id的{{1}}字段中。
