我怎么称呼这个Createquery呢。来自集成了OpenLayers的jsp页面的java文件？

Question

package database;


    import java.io.IOException;
    import java.sql.Connection;
    import java.sql.PreparedStatement;
    import java.sql.SQLException;
    import database.Dbconnect;

    public class CreateQuery {
        Connection conn;

        public CreateQuery() throws ClassNotFoundException, SQLException, IOException {
            conn=new Dbconnect().returnDatabaseConnection();
        }
        public int addNewLayertoDB(String feature_name,String shape,int Latitude , int Longitude , int feature_geom , String feature_details){
            try {
                PreparedStatement statement = null;
                String table_name = feature_name + "_" + shape; 
                String query = "CREATE TABLE EtherMap "+table_name+" ("+ feature_name+" (20))";
                statement = conn.prepareStatement(query);
                statement.setString(1, feature_name);
                statement.execute();
                String squery = "ALTER TABLE EtherMap" +table_name+"  ADD COLUMN geom int , ADD COLUMN shape character(10)";
                return 1;
                } catch (SQLException ex) {
                return 0;
            }
        }




        public void closeConn() throws SQLException {
            if (conn != null) {
                this.conn.close();
            }
        }

    }

我已经编写了这个createquery。在postgres中创建表的java代码。在jsp页面中使用javascript在开放层地图上绘制任何内容时，我需要调用它。我怎么称呼它？我必须用豆子吗
