Sure, you can create a Spring Boot application that reads a SQL query from a file and runs it every certain time. You can use a scheduler like Quartz to schedule the query execution. The result of the query can be stored in a file or database.
hello, I want to create a spring boot app that reads a sql query from a file and run that query every certain time and stores the result in another file.

I have tried to create a service that reads the query from a file and run the query but I am not sure how to schedule this service to run every certain time and store the result in another file.

Here is my service class:

```
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

        BufferedReader reader = new BufferedReader(new FileReader(queryFile));
        String query = reader.readLine();
        Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb", "root", "
