最有效的ResultSet转换为JSON？

import com.fasterxml.jackson.databind.ObjectMapper;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class ResultSetToJsonConverter {
    public static String convertToJson(ResultSet resultSet) throws SQLException {
        List<Map<String, Object>> resultList = new ArrayList<>();
        
        while (resultSet.next()) {
            Map<String, Object> rowMap = new HashMap<>();
            int columnCount = resultSet.getMetaData().getColumnCount();
            
            for (int i = 1; i <= columnCount; i++) {
                String columnName = resultSet.getMetaData().getColumnName(i);
                Object columnValue = resultSet.getObject(i);
                rowMap.put(columnName, columnValue);
            }
            
            resultList.add(rowMap);
        }
        
        ObjectMapper objectMapper = new ObjectMapper();
        String json = objectMapper.writeValueAsString(resultList);
        
        return json;
    }
}
