jpa - ManyToOne relation connect via embbeded fielld -


jpa/spring-data question

i have class plant has embbededid plantid , have class image embbeded field plantid

this means each image connect plant. connection 1 many (one plant many image)

i tried that(which doesnt work)

@entity public class plant{      @embbededid      plantid id }  @entity public class image{      @id      long id       @embbeded      plantid plantid       @manytoone      plant plant  }

how can fix code result i'm looking for? thanks

oak

edit: how can map columns manytoone relation if have composite id plant?

all missing once remove plantid embeddable join column definitions on manytoone mapping jpa knows foreign keys use match id fields in plant. like:

@manytoone @joincolumns({         @joincolumn(name="fk_1", referencedcolumnname="pk1"),         @joincolumn(name="fk_2", referencedcolumnname="pk2"),         @joincolumn(name="fk_3", referencedcolumnname="pk3")          }) plant plant;

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
