java - How to make Hibernate to use SequenceHiLoGenerator for JPA GenerationType.AUTO on Oracle? -

-

i have table id below, hibernate uses org.hibernate.id.sequencegenerator instead of sequencehilogenerator generationtype.auto, how can tell hibernate use sequencehilogenerator?

@id @sequencegenerator(name="admin_seq", sequencename="unique_id") @generatedvalue(strategy=generationtype.auto, generator="admin_seq") private long id

if use generationtype.sequence, hibernate use sequencehilogenerator, need use generationtype.auto compatibility mysql.

i have tried using @genericgenerator, works oracle complained mysql: org.hibernate.dialect.mysqldialect not support sequences. 

@genericgenerator(name = "admin_seq", strategy = "org.hibernate.id.sequencehilogenerator",         parameters = {                 @parameter(name = "sequence", value = "unique_id"),                 @parameter(name = "max_lo", value = "50") }) @generatedvalue(strategy=generationtype.auto, generator="admin_seq") private long id

i tried using sequencestylegenerator setting hibernate.id.new_generator_mappings=true in hibernate properties. doesn't work either.

strategy = generationtype.auto should work against mysql identity column though you've configured sequence too. sequencegenerator used when running against oracle, ignored when running against mysql.

in persistence.xml should switch hibernate.dialect property between correct values oracle dialect , mysql dialect.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
