Fangwei Second Development Tutorial158

IntroductionFangwei is an open-source data integration platform that enables users to connect to different data sources, transform and enrich data, and build data pipelines. It offers a range of capabilities for data integration, including data extraction, data cleansing, data transformation, and data loading. Fangwei's second development (Fangwei SDK) provides a set of tools and APIs that allow developers to extend the functionality of Fangwei and build custom applications on top of it.

Getting Started with Fangwei SDKTo get started with Fangwei SDK, you need to install the SDK and set up the development environment. The SDK is available for download from the Fangwei website. Once you have installed the SDK, you can create a new project and add the Fangwei library to your project. The following code shows how to create a new Fangwei project in Java:```java
import ;
import ;
public class CreateProject {
public static void main(String[] args) throws Exception {
// Create a Fangwei client
FangweiClient client = new FangweiClient();
// Create a new project
FangweiProject project = ("My Project");
// Print the project id
(());
}
}
```

Building a Custom ConnectorOne of the key features of Fangwei SDK is the ability to build custom connectors. Custom connectors allow you to connect to data sources that are not natively supported by Fangwei. To build a custom connector, you need to create a class that implements the FangweiConnector interface. The following code shows an example of a custom connector that connects to a MySQL database:```java
import ;
import ;
import ;
import ;
import ;
import ;
import ;
public class MySQLConnector extends FangweiConnector {
@Override
public void connect(FangweiConnectorContext context) throws Exception {
// Get the connection parameters from the context
String host = ("host");
String port = ("port");
String database = ("database");
String user = ("user");
String password = ("password");
// Create a connection to the MySQL database
Connection connection = ("jdbc:mysql://" + host + ":" + port + "/" + database, user, password);
// Set the connection on the context
(connection);
}
@Override
public void read(FangweiConnectorContext context) throws Exception {
// Get the query from the context
String query = ("query");
// Create a statement and execute the query
Statement statement = ().createStatement();
ResultSet resultSet = (query);
// Get the Fangwei record factory from the context
FangweiRecordFactory recordFactory = ();
// Process the result set and create Fangwei records
while (()) {
FangweiRecord record = ();
("id", ("id"));
("name", ("name"));
("age", ("age"));
// Write the record to the output stream
().write(record);
}
// Close the statement and result set
();
();
}
@Override
public void disconnect(FangweiConnectorContext context) throws Exception {
// Close the connection
().close();
}
}
```

Developing Data PipelinesFangwei SDK also provides a range of tools for developing data pipelines. Data pipelines are workflows that orchestrate the flow of data between different data sources and destinations. To create a data pipeline, you can use the Fangwei Pipeline Builder. The Pipeline Builder provides a graphical user interface for creating and managing pipelines. You can drag and drop connectors and transformers to build a pipeline that meets your requirements.

ConclusionFangwei SDK is a powerful tool that allows developers to extend the functionality of Fangwei and build custom applications on top of it. With Fangwei SDK, you can build custom connectors, develop data pipelines, and create complex data integration solutions.
