params.put("name", name);
return baseDao.query("select * from t_demo d where d.c_name like ${name}", params);

Research direction

Start with the reported baseDao.query call and the SQL parser path handling the ${name} expression, comparing behavior with version 1.0.15 and 1.1.16/1.1.18. Reproduce the MySQL query, identify the parser regression, and add coverage showing that the expression is accepted without the reported ParserException.
