java - 使用 IntelliJ IDEA 插件在 Siddhi SDK 中启动 HL7 服务时出现端口绑定(bind)错误

Question

我尝试使用 IntelliJ 插件开发 Siddhi 扩展。当我尝试在任何端口上配置“hl7”源时，HL7Service 似乎启动了两次。这不起作用，因为网络端口只能打开一次。

我检查没有其他 Siddhi 实例正在运行，并且我尝试了许多不同的端口。

@App:name('HL7SiddhiApp')
@App:description('Description of the plan')
@source(type = 'hl7', port = "7777", hl7.encoding = "er7", @map(type = 'text'))
define stream hl7stream (message string);

@sink(type = 'log', @map(type = 'passThrough'))
define stream outStream (message string);

from hl7stream
select message
insert into outStream;

您可以尝试以下命令来检查本地计算机上正在使用哪些端口以及哪个进程正在使用它。尝试输出中不存在的端口。

sudo netstat -tulpn

• t:TCP
• u:udp
• l:监听端口
• p:进程 n:网络
