JAVA调用存储过程

public static void pressure_pro(String tableName) throws SQLException {

        JdbcUtil.getConnection();

        Connection conn = JdbcUtil.getConnection();

//call为固定格式  pressure_pro为存储过程名称  ？为参数

        CallableStatement cstmt = conn.prepareCall("{call pressure_pro(?)}");

        cstmt.setString(1, tableName); //传入参数

        cstmt.execute();  //执行存储过程

       // JdbcUtil.closeAll();

       }
