String findSql="select id from tb_user_openid where user_id=? and open_id=?";

jdbcTemplate.queryForMap(findSql, user.getId(), openid);

执行findSql报错信息：

SQLErrorCodes loaded: [DB2, Derby, H2, HSQL, Informix, MS-SQL, MySQL, Oracle, PostgreSQL, Sybase, Hana]

解决方法：

数据库表字段的数据类型不匹配，字符串类型要加上单引号

String findSql="select id from tb_user_openid where user_id='?' and open_id='?'";

jdbcTemplate.queryForMap(findSql, user.getId(), openid);
