HQL-通过电子邮件或带点号（'。'）的字符串查询始终返回空集

Question

This is my HQL Query

Query query = getCurrentSession().createQuery(
            "from User where username = :usersName ");
    query.setParameter("usersName", usersName);

Now if the user name contains dot'.' character its returning empty set other wise its returning the user details.

What I have tried?

Hibernate having difficulty with '@' character in HQL

Executed the sql query in the server its returning the user details.

Concatenated the parameters directly in query string getting same error.

Tried Criteria Query Got the same problem

where might be the problem?

尝试使用此方法： query.setString("usersName", usersName);

Answer 2

You can try this:

query.setString("usersName", usersName.replaceAll("@", "/@"));
