java ee - JPA and order of columns in the database -


i'm using eclipselink persistence provider. there way specify order in columns appear in database? column-order in database doesn't match attribute-order in entities. far i've understood hibernate order columns alphabetically can't find specifications eclipselink.

eclipselink sorts mappings , columns based on weight of mapping. weight not set other ensure baisc mappings first, , relationship mappings second.

you can set weight mapping if desire using descriptorcustomizer. set descriptor not order mapping weight, order specified used (setshouldordermappings(false)).

public void mycustomizer implements descriptorcustomizer {   public void customize(classdescriptor descriptor) {     descriptor.getmappingforattributename("name").setweight(2);   } }

there have been recent changes weighting of mappings in 2.2 development, mappings sorted name within same weight levels.
