在启动SpringBoot应用程序时使用JDBC驱动程序创建Postgres数据库？

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>版本号</version>
</dependency>

spring.datasource.url=jdbc:postgresql://localhost:5432/数据库名
spring.datasource.username=用户名
spring.datasource.password=密码
spring.datasource.driver-class-name=org.postgresql.Driver

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

@Component
public class DatabaseInitializer {

    private final JdbcTemplate jdbcTemplate;

    @Autowired
    public DatabaseInitializer(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public void createTable() {
        String sql = "CREATE TABLE IF NOT EXISTS users (id SERIAL, name VARCHAR(255), email VARCHAR(255))";
        jdbcTemplate.execute(sql);
    }
}

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
        DatabaseInitializer databaseInitializer = context.getBean(DatabaseInitializer.class);
        databaseInitializer.createTable();
    }
}
