如何解决将枚举值时“无法推断SQL类型用于枚举实例”的错误？

我想开发一个简单的CRUD应用程序，即在JSON格式接收数据，处理它，并把它放在一个PostgreSQL表。一个在表中，性别字段，由枚举表示。

在这里，我尝试添加使用邮差的条目：

{
    "employeeId": 1,
    "firstName": "Ada",
    "lastName": "Lovelace",
    "departmentId": 3,
    "jobTitle": "Senior",
    "gender": "FEMALE",
    "dateOfBirth": "1815-12-10"
}

下面是DAO-层代码：

@Override
public void addEmployee(Employee employee) {
    String sql = "INSERT INTO employees(employee_id, first_name, last_name, department_id, job_title, gender, date_of_birth) VALUES (?, ?, ?, ?, ?, CAST(? AS gender), ?)";
    getJdbcTemplate().update(sql, employee.getEmployeeId(), employee.getFirstName(), employee.getLastName(),
            employee.getDepartmentId(), employee.getJobTitle(), employee.getGender(), employee.getDateOfBirth());
}

其结果是，我得到：500内部服务器错误和

"PreparedStatementCallback; bad SQL grammar [INSERT INTO employees(employee_id, first_name, last_name, department_id, job_title, gender, date_of_birth) VALUES (?, ?, ?, ?, ?, CAST(? AS gender), ?)]; nested exception is org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of com.way.dto.Gender. Use setObject() with an explicit Types value to specify the type to use."

请帮帮我，我谷歌这个问题好几天了，我无法找到一个解决方案
