u mean like that?
I would add another space in 53 and 54.
but is it even possible to do what i want? i.e. inject a list of objects in my Config class?
crap, still doesnt work
It should, is that the complete Config-class?
Oh, you need getter and setter for the private-field. And you need the
@ConfigurationProperties("xxx") on that class.on that class. on which one? on my BankAccountConfig or BankAccount?BankAccountConfig
but i dont understand what to write between quotes
Could you create another namespace before the config bankAccounts?
Maybe empty is ok.
my application.yaml looks like this. im not sure i understand what u mean
I reproduced your problem and it works for me.
so do i need to have
@ConfigurationProperties annotation?Yes.
I send you my working-example
1 Moment
My main class:
My BankAccountConfig:
My BankAccount:
My Config:
Output:
You realy need the
@EnableConfigurationProperties(BankAccountConfig.class)!idk man. previously i had
and everything was fine. i didnt even need to have
@EnableConfigurationProperties(BankAccountConfig.class)@EnableConfigurationProperties(BankAccountConfig.class) should go to the appconfig. Not the BankAccountConfig
Do you have setter for BankAccounts in BankAccountConfig?idk its a good idea
nope, didnt need it
bc BankAccount is:
No no no, I did not meant the application.yml, I meant the AppConfigClass!
You need to add
@EnableConfigurationProperties(BankAccountConfig.class) to the application-config-java-class!
I am pretty sure you need the setter. But I guess the setter is automatically generated by the @Setter annotation.yep
Ok, did you add
@EnableConfigurationProperties(BankAccountConfig.class) to the application-config-java-class?but i have like 5 config classes. why do i need to add only BankAccountConfig class to my application config java class?
Hm, did you already have a
@EnableConfigurationProperties in your application-config-java-class?nope. dont have it anywehere
BankAccountConfig Is not a application-config-java-class by-the-way.i never said it is 😦
Ah ok.
np
but i still dont get it
why cant this work?
why is Spring so against it?
it IS a list of objects
Because bankAccounts are "configuration-properties" and not plain properties.
Only
@EnableConfigurationProperties(BankAccountConfig.class) allow spring to call the constructor of the class "BankAccount".
The word "ConfigurationProperties" have a very special meaning.ok, but why did the old config versin work?
This works great, do not change that!
i know it works, but i need to change it
You might consider to remove the
@Component. And you might consider to remove the prefix=.
Why do you need to change it?i need to separate bank accounts. i want to have two separate lists. smth like this:
i have two banks:
bank1 and bank2.
and i want to have a list of accounts for each of themoh, I think I got your question wrong the whole time.
doesnt matter. its ok
-_-
and now i need to structure my application.yaml and tweak my BankAccountConfig a little
and idk how to do it properly
This might work
ok. but u see, i have this config
and in the 51st line there are accounts of bank1
id like to separate config and properties by the banks
like in the 41st line
idk if u understood me
haha
In line 43-45 the fields of bank1 do not match the fields in the class
BankAccountok, ill show u what i want to achieve
i want to have this application.yml
ah, it is getting clearer.
and in my BankAccountCOnfig i want to have everything like this:
but
@Value("${paymentImport.balticGateway.bank1.bankAccounts}") doesnt work, because Spring wont (for some reason) accept listAre you sure you could use
@Value in a class that have the @ConfigurationProperties annotation?im just showing you pseudocode what i want to do 😄
Can you give an example of two bankacounts in line 7? The configuration looks like there is only one bank-account possible.
"LT516126515919194" for example. doesnt matter tbh. why are you asking?
You wrote this pseudocode: but one iban is a string.
String != List<BankAccount>
huh?
you asked me about 7th line
not 9th
oh, wiat
so the question is still there
I give up, I dont get your question. Maybe someone else can help.
😄
maybe someone else can help me out?
