Add EntityMapper for SQLInsertClause.populate()

[jojoldu]

Hi @eXsio

QClass created with Entityql as below will fail when using SQLInsertClause.populate().

    @Test
    void sqlPopulateInsert() throws Exception {
        //given
        Book entity = Book.builder()
                .bookNo(1)
                .bookType(BookType.IT)
                .build();

        //when
        sqlQueryFactory.insert(qBook)
                .populate(entity, BeanMapper.DEFAULT)
                .execute();

        //then
        List<Book> results = bookRepository.findAll();
        assertThat(results).hasSize(1);
        assertThat(results.get(0).getId()).isEqualTo(1L);
        assertThat(results.get(0).getBookType()).isEqualTo(BookType.IT);
    }

This is the insert query I intended,

insert into book (book_type, book_no) values (?, ?)

Actually, it works like this:

insert into book values ()

The reason was that the property key and the column name were different, and there was an issue that could not be recognized.

In BeanMapper supported by Querydsl-sql, the property key and the column name had to match.

This problem is also recognized in Querydsl-sql, so AnnotationMapper is supported.
However, AnnotationMapper uses the @column annotation of querydsl, so it cannot be used in QClass created with Entityql.

So I created a Mapper class that uses JPA's @column annotation.
I changed the test code above to EntityMapper and it worked fine.

Below is a link to the code I tested.

I'll ask for confirmation.

Hello, Thank you for the contribution!

Would you be so kind to provide an automated test that proves this code works and shows how to use it?

Please make sure that the overall code coverage is not decreased.

@eXsio
OK.
I will write the test code as soon as possible and commit it.

@eXsio Hello.
Added a test case where an issue occurs.

A successful test case using EntityMapper added as PR was also added.

Please confirm.
