如何在spring的mysql服务中运行插入脚本？

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.stream.Collectors;

@Component
public class DataLoader {

    private final JdbcTemplate jdbcTemplate;
    private final ResourceLoader resourceLoader;

    @Autowired
    public DataLoader(JdbcTemplate jdbcTemplate, ResourceLoader resourceLoader) {
        this.jdbcTemplate = jdbcTemplate;
        this.resourceLoader = resourceLoader;
    }

    @PostConstruct
    public void loadData() throws IOException {
        Resource resource = resourceLoader.getResource("classpath:insert_data.sql");
        String sqlScript = new BufferedReader(new InputStreamReader(resource.getInputStream()))
                .lines().collect(Collectors.joining("\n"));

        jdbcTemplate.execute(sqlScript);
    }
}
