// Create JDBC, it is recommended to execute it only once when the project starts
MagicianJDBC.createJDBC()
        .addDataSource("a", dataSource)// Add data source, this method can be called multiple times to add multiple data sources
        .defaultDataSourceName("a");// Set the name of the default data source
