如何用jdbcTemplate在Oracle中插入文件？

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:XE" />
    <property name="username" value="your_username" />
    <property name="password" value="your_password" />
</bean>

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource" />
</bean>

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

@Repository
public class FileDAO {
    private final JdbcTemplate jdbcTemplate;

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

    public void insertFile(String fileName, File file) {
        String sql = "INSERT INTO files (name, content) VALUES (?, ?)";
        jdbcTemplate.update(sql, fileName, file);
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class FileService {
    private final FileDAO fileDAO;

    @Autowired
    public FileService(FileDAO fileDAO) {
        this.fileDAO = fileDAO;
    }

    public void uploadFile(String fileName, File file) {
        fileDAO.insertFile(fileName, file);
    }
}
