In my project, I fetched all data with Stream but encoding didn't work.
My code looks like:
Repository:
@QueryHints(value = {
@QueryHint(name = HINT_FETCH_SIZE, value = "" + Integer.MIN_VALUE),
@QueryHint(name = HINT_CACHEABLE, value = "false"),
@QueryHint(name = HINT_READONLY, value = "true"),
})
Stream<Book> findAllBy();
Service:
try (var allBooks = bookRepository.findAllBy())
{
allBooks.forEach(book -> {
logger.info("Coming book name={}", book.getName());
// we need to free the memory
entityManager.detach(book);
});
}
When I fetch it, book name look like: ????, en ???? ??, ????? ????? ?? ...
Then I implement encoding on database url: JPA utf-8 characters not persisted But it didn't work also.
Is there any suggestion? How can I solve this encoding problem?
Solved like:
I gave environmental variable for file-encoding.
-Dfile.encoding=utf8
