i was given an advice to use structural pattern matching
but i don't know how to use it properly, so you have to google for it yourself

i wanna tracking change of object. what field change? and what is the change value?
ĐV
for write log
ĐV
Or you need full set of different fields including referenced ones?

if you don't need to define fields subset for comparison you can use javers

checking field by field be too expensive for my memory and take time, cuz my object has a lot of field

maybe you can use for it spring AOP

this way doesn't treat nested objects

i mean that you'll only see that some object has changed, but not the entire change

when don't i have another way? i think i must do that

i've written smth like that a long ago, and i didn't find a better way than recursion. i think it is ok, if your object isn't too big to cause stackoverflow)
btw, i advise you to include some mark-interface for your pojos, so that it's easier for you to detect nested objects
