Biz-SIP中间件之HelloWorld(1)——实现sink服务的穿透式访问
HelloWorld项目版本库:https://gitee.com/szhengye/biz-sip-helloworld.git
一、实现sink服务的穿透式访问
在Biz-SIP中间件中,外部应用不管通过source模块还是开放平台接口,都无法直接访问基于app层背后的sink层服务,但可以通过app层的sink/sample-sink-service,把sink服务实现开放访问。
sink服务的穿透式访问,调用关系如下图所示:

sink层的sample-sink-bean-sink服务,是sink-beank类型服务,该服务的调用是基于JSON接口的。
主要实现步骤如下:
1、我们先创建sink层的sample-sink-bean-sink服务:
- 在“biz-sip-sink”模块下,创建“sample-sink-bean-sink”子模块,新建SpringBoot启动类SampleSinkBeanSinkApplication和配置文件application.yml,具体参见源码;
- 创建SampleSinkBeanService类,该类实现JSONObjectSinkBeanInterface接口,并实现process()方法,实现对传入标准JSON报文的处理:
@Service
public class SampleSinkBeanService implements JSONObjectSinkBeanInterface {
@Override
public JSONObject process(JSONObject packMessage) throws BizException {
String message = (String)packMessage.get("message");
packMessage.set("message","sample-sink-bean-sink: Hello,"+message);
return packMessage;
}
}
- 在sink.yml中,定义sample-sink-bean-sink服务:
- id: sample-sink-bean-sink
type: rest
url: http://sample-sink-bean-sink/sink
connector:
type: sink-bean
class-name: com.sample.sink.samplesinkbean.service.SampleSinkBeanService
spring-bean: true
2、在app层中,在service.yml中把sample-sink-bean-sink服务,通过sink-bean方式直接开放出去:
- bizServiceId: sink/sample-sink-service
type: sink-service
sinkId: sample-sink-bean-sink
3、通过app层的开放平台OpenAPI接口,可以直接进行测试访问:
$ curl -H "Content-Type:application/json" -H "Biz-Service-Id:sink/sample-sink-service" -X POST --data '{"message":"world"}' http://localhost:8888/api|jq
{
"code": 0,
"message": "success",
"extMessage": null,
"traceId": "c6a374d195f3450e8c99da23c8a2077b",
"parentTraceId": null,
"timestamp": 1633593193550,
"data": {
"message": "sample-sink-bean-sink: Hello,world"
}
}
