Does Spring Boot automatically resolve message keys in javax and hibernate validation annotations

Question

I was writing a Spring Boot Application. I wanted to know does Spring Boot automatically resolve message keys in javax and hibernate validation annotations. For example:

@NotEmpty(message = "${message.key}")
String name;

I have provided @PropertySource in my application with message properties file and file is also in my classpath. The keys are resolving with @Value but they are not being resolved in validation annotations.

What could be the reason for this?

Do I need configure a message source bean? Because I have seen examples working without configuring the message source bean.

Answer 1

Are your messages in the correct place? Spring Boot automatically registers a MessageSource bean for you, so you should put your messages in the src/main/resources/messages.properties file. If you have enabled the auto-configuration and also have hibernate-validator dependency on the classpath, everything should work out of the box.

Also @PropertySource is related to application's configuration properties and not messages so the fact that it's not resolving them is to be expected ^^
