API订阅写入示例

API订阅写入示例

1. 依赖

使用Equipment Client库需要配置maven仓库访问和导入edge-management-client的依赖库

maven settings.xml仓库访问配置:

  <servers>
    <server>
      <id>snapshot</id>
      <username>matrix</username>
      <password>hVisions!maven</password>
    </server>
    <server>
      <id>release</id>
      <username>matrix</username>
      <password>hVisions!maven</password>
    </server>
    <server>
      <id>nexus</id>
      <username>matrix</username>
      <password>hVisions!maven</password>
    </server>
  </servers>
   <mirrors>
	<mirror>  
		<id>release</id>
		<mirrorOf>*</mirrorOf>
		<name>nexus hvisions</name>
		<url>http://58.247.122.126:8022/repository/maven-public/</url>
	</mirror> 
  </mirrors>

gradle:

    implementation 'com.hvisions:edge-management-client:2.2.2'

maven pom:

    <dependency>
        <groupId>com.hvisions</groupId>
        <artifactId>edge-management-client</artifactId>
        <version>2.2.2</version>
    </dependency>

2. 配置RabbitMQ, Redis, Token获取

Equipment Client库基于SpringBoot进行开发,使用了RabbitMQ,Redis进行数据处理,通过集成HttpClient方式实现接口调用。因此在使用时,需要在SpringBoot
(application. yml)对RabbitMQ、Redis、Token获取进行配置。

配置示例如下:

spring:
  redis:
    host: 127.0.0.1
    port: 6379
iot:
  broker:
    rabbitmq:
      host: ${rabbitmq.host:127.0.0.1}
      port: ${rabbitmq.port:5672}
      username: ${rabbitmq.username:guest}
      password: ${rabbitmq.password:guest}
      exchangeName: ${rabbitmq.exchangeName:hiot.subscribe}
      exchangeType: ${rabbitmq.exchangeType:topic}
      queueType: ${rabbitmq.queueType:classic}      
      maxLength: ${rabbitmq.maxLength:50000}
      overflow: ${rabbitmq.overflow:reject-publish} 
      enabelSsl: ${rabbitmq.enabelSsl:false}
      keyStore: ${rabbitmq.keyStore:rabbitmq-client.p12}
      keyStorePassword: ${rabbitmq.keyStorePassword:password}
      trustStore: ${rabbitmq.trustStore:rabbitmq-server.keystore}
      trustStorePassword: ${rabbitmq.trustStorePassword:password}
      basicAck: ${rabbitmq.basicAck:true}
api:
  setting:
    server: http://127.0.0.1:9000
    username: admin
    password: 111111
    enableAuth: true      

2.1 Redis配置

Redis采用的是SpringBoot实现的标准的Redis配置,详细配置项参考SpringBoot官方文档Redis部分 ( https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#application-properties.data )

2.2 RabbitMQ配置

RabbitMQ配置说明如下:

名称 说明 是否必须 默认值
host RabbitMQ服务地址 127.0.0.1
port RabbitMQ端口 5672
username 登录到RabbitMQ服务的用户 guest
password 登录到RabbitMQ服务的密码 guest
exchangeName iot数据使用的Exchange名称,保持默认hiot不变 hiot
exchangeType iot数据使用的Exchange类型,保持默认topic不变 topic
enabelSsl 是否启用SSL连接,在RabbitMQ Server启用了SSL时配置成true,否则设置成false false
keyStore 采用SSL连接时使用的keystore文件,enabelSsl为True时有效
keyStorePassword keystore文件的密码,enabelSsl为True时有效
trustStore 采用SSL连接时使用的truststore文件,enabelSsl为True时有效
trustStorePassword truststore文件的密码,enabelSsl为True时有效
basicAck 是否自动确认 true

2.3 Token获取配置

Equipment Client库通过配置API Token获取方式,实现对Client库提供的API进行调用。

Token配置说明如下:

配置项(api.setting.*) 说明 默认值
server HiperMatrix平台网关地址 http://127.0.0.1:9000
username 用户名 admin
password 密码 111111
enableAuth 启用token获取失败重试 true

3. 启动类中扫描依赖中的Bean

启动类通过注解@ComponentScan将路径为"com.hvisions.edge.equipment"包下的Bean扫描到当前框架中

@ComponentScan(basePackages = {"com.hvisions.edge.equipment"})

4.订阅接口调用

4.1 调用订阅EquipmentService接口

调用订阅接口入参描述:

参数名称 说明
equipmentId 设备id
equipmentName 设备名称
equipmentCode 设备编码
fieldName 设备属性标识符
fieldNames 设备属性标识符列表
  • equipmentName:指设备名称,对应HiperMatrix中设备管理列表的设备名称。

image-111111

  • fieldName:指设备标识符,对应HiperMatrix中设备管理中的设备属性列表的标识符。

image-111111

Equipment Client提供了四种不同设备属性订阅接口:

  • 根据设备id(equipmentId)订阅设备单个属性标识符(fieldName)和多个属性标识符(fieldNames)采集数据接口
     subsById(String equipmentId, String fieldName, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
     subsById(String equipmentId, List<String> fieldNames, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
  • 根据设备名称(equipmentName)订阅设备单个属性标识符(fieldName)和多个属性标识符(fieldNames)采集数据接口
     subsByName(String equipmentName, String fieldName, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
     subsByName(String equipmentName, List<String> fieldNames, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
  • 根据设备编码(equipmentCode)订阅设备单个属性标识符(fieldName)和多个属性标识符(fieldNames)采集数据接口
     subsByCode(String equipmentCode, String fieldName, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
     subsByCode(String equipmentCode, List<String> fieldNames, EquipmentService.FieldConsumer fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);
  • 自定义队列名称(queueName)订阅多组设备的属性标识符List&lt;EquipmentField>, EquipmentField包含设备id(equipmentId),属性标识符(fieldName)采集数据接口
     void subsGroup(String subName, List<EquipmentField> equipFieldNames, FieldConsumerTs fieldConsumer,java.util.function.Consumer<BrokerEvent> eventConsumer);

4.2 回调接口FieldConsumer描述

FieldConsumer入参描述:

参数名称 说明
equipmentInfo 设备数据信息
fieldName 设备属性标识符
value 设备订阅数据
    public interface FieldConsumer {
        void accept(EquipmentData equipmentInfo, String fieldName, Object value);
    }

4.3 回调接口状态BrokerEvent描述

BrokerEvent入参描述:

参数名称 说明
name rabbitmq连接名称
status 连接状态,CONNECTED/DISCONNECTED
msg 连接日志内容
    public interface FieldConsumer {
        void accept(EquipmentData equipmentInfo, String fieldName, Object value);
    }

5. 订阅接口案列

5.1 引用EquipmentService

声明EquipmentService,并通过注解@Autowired注入到当前使用类中

  @Autowired
  EquipmentService equipmentService;

5.2 引用注入的EquipmentService,调用订阅函数

如根据设备名称(equipmentName)为海德汉机床,设备属性标识符(fileName) main_axle_load 调用函数subscribeByName,
并将订阅数据写入到回调函数中

   equipmentService.subsByName(equipmentName, fileName, (equipmentData,fieldName, value)  -> {
        log.info("订阅设备数据:{}", equipmentData);
        log.info("订阅设备标识符:{}", fileName);
        log.info("订阅采集数据:{}", value);
   },brokerEvent -> {
            log.info("rabbitmq连接名称:{}",brokerEvent.getName());
            log.info("连接状态:{}",brokerEvent.getStatus());
            log.info("连接日志内容:{}",brokerEvent.getMsg());
    });

回调函数返回结果为:设备数据(equipmentData),设备标识符(fieldName), 订阅数据(value)

equipmentData数据格式:

{
  "id":"6879310550845624320",
  "name":”海德汉机床",
  "code":"海德汉机床"
 }

fieldName数据格式:

{
  fieldName:"main_axle_load"
}

value数据格式:

{
  "id":"6879310550845624320",
  "timestamp":"2022-02-23T17:53:22.346+08:00",
  "_type":"haidehanjichuang",
  "main_axle_load":0.8700000047683716
}

5. 数据写入案列

声明HttpBuilderInstance,并通过注解@Autowired注入到当前使用类中

 @Autowired
 private HttpBuilderInstance httpBuilder;

构建提供API写入的EquipmentClient,httpBuilder为Springboot的Bean在全局变量加载之后,因此不要将EquipmentClient定义为全局变量。

 EquipmentClient equipmentClient = httpBuilder.getInstance().getClient(EquipmentClient.class);

如根据设备编码(code)为海德汉机床,设备属性标识符(fileName) main_axle_load 调用函数writeByCode,
将数据写入到函数中

 ResultVO<WriteResult> result = equipmentClient.writeByCode(code, fileName, value);

函数返回结果为result:

{
  "data": {
    "status": "ok",
    "error": null,
    "duration": null,
    "details": [],
    "success": true
  },
  "code": 200,
  "message": null
}

status为ok表示数据写入成功
