如何将数据从 java 类推送到 Wso2 DAS [英] how to push data from java class to Wso2 DAS
问题描述
是否有任何文档或分步过程指导我们如何使用 WS02 DAS 从 Java 类对象中提取数据并使用 WS02 Dashboards 使用此数据显示报告.
Is there any document or step by step process which guides us on how we can use WS02 DAS to pull data from java class objects and display reports using this data using WS02 Dashboards.
任何帮助将不胜感激.
推荐答案
首先您可以通过指定属性来创建事件流，并提及您需要持久化的属性.当事件到达流时，这些将存储在事件表 [1] 中.
First You can create an Event Stream by specifying attributes and mention what are the attributes you need to persist. When events arrives to the streams, those will be stored in Events tables [1].
然后您可以为该事件流创建一个事件接收器 [2].创建事件流时，您可以使用 Thrift、Soap、Http、Mqtt、JMS、Kafka 和 Web 套接字等协议.您可以编写一个简单的 Java 应用程序来将数据发布到您根据您选择的消息格式协议创建的 DAS Receiver.例如，如果您创建 SOAP 接收器，则可以使用肥皂消息格式的数据，并且如果您创建 HTTP 接收器，则可以使用 JSON 格式.
Then you can create an Event Receiver for that Event Stream [2]. When creating an event stream you can use a protocol such as Thrift, Soap, Http, Mqtt, JMS, Kafka and Web sockets. You can write a simple Java Application to publish data to DAS Receiver you created on message format protocol which you have selected. For an instance if you create SOAP receiver you can use data on soap message format and also if you create a HTTP receiver you can use JSON format.
您可以创建仪表板和小工具来可视化由持久流创建的事件表 [3].请注意，此事件表包含 WSO2 DAS 收到的所有事件，您可以使用 spark SQL [4] 处理这些数据并创建多个可在 Analytics Dashboard 中使用的流.
You can create a dashboard and gadgets to visualize Event table which was created by your persistent stream [3]. Please note that this event table consist all the events WSO2 DAS received, you can process these data by using spark SQL [4] and create several streams which could be used in Analytics Dashboard.
