QueryDslJdbcTemplate#queryForObject(SQLQuery, ExpressionBase<T>) should accept Expression<T> as 2nd param [DATAJDBC-34]

[spring-projects-issues]

ryo murai opened DATAJDBC-34 and commented

QueryDslJdbcOperations#queryForObject(SQLQuery, ExpressionBase<T>)
breaks a spec described its javadoc: The results are mapped using the {@link ExpressionBase} which could be a QBean or a MappingProjection.
Because QBean(extends RelationalPathBase) is not an ExpressionBase but Expression, I can't pass a QBean object as ExpressionBase. The compilation fails at below line.
template.queryForObject(sqlQuery, QBeanObj)
