how to use mysql table's regular expression match kafka real time date by java

To match Kafka real-time data with a regular expression in Java, you can use the following steps:

1. First, connect to your MySQL database using the JDBC driver.

2. Retrieve the Kafka real-time data from the Kafka topic.

3. Create a regular expression pattern using the java.util.regex.Pattern class.

4. Loop through the Kafka data and use the Matcher class to match the regular expression pattern with the data.

5. If the pattern matches, then you can insert the data into the MySQL table.

Here's an example code snippet that demonstrates how to use regular expression matching with Kafka real-time data using Java:

import java.sql.*;
import java.util.regex.*;

public class KafkaRegexMatchExample {
    public static void main(String[] args) throws SQLException {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";
        
        // Connect to MySQL database
        Connection connection = DriverManager.getConnection(url, username, password);
        
        // Retrieve Kafka real-time data
        // TODO: Implement Kafka consumer
        
        // Create regular expression pattern
        Pattern pattern = Pattern.compile("regex_pattern_here");
        
        // Loop through Kafka data and match with pattern
        while (true) {
            String kafkaData = getKafkaData(); // Get Kafka data
            
            Matcher matcher = pattern.matcher(kafkaData);
            
            if (matcher.matches()) {
                // Insert data into MySQL table
                PreparedStatement statement = connection.prepareStatement("INSERT INTO mytable (column1, column2) VALUES (?, ?)");
                statement.setString(1, matcher.group(1));
                statement.setString(2, matcher.group(2));
                statement.executeUpdate();
            }
        }
    }
    
    private static String getKafkaData() {
        // TODO: Implement Kafka consumer logic to retrieve data
    }
}

Note that this is just an example, and you'll need to modify it based on your specific requirements.
