Spring-boot how to import all i18n messages of all jar dependencys projects?

I want to import all the messages.properties files, which are contained in the src/main/resource/messages locations of ALL the jar dependencies of my project. for example: Project A import -> Project B, and I need to load all message properties.

I tried:

@Bean
public ReloadableResourceBundleMessageSource messageSource() {
  ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
  messageSource.setBasenames("classpath:/messages", "classpath:/messages/messages");
  messageSource.setCacheSeconds(3600);
  return messageSource;
}

But it did not work =(.How can I do this with spring-boot?

Here's my project structure:

project A
+-- project-server-business
¦   +-- src
¦   ¦   +-- main
¦   ¦   ¦   +-- java
¦   ¦   ¦   +-- resources
¦   ¦   ¦   ¦   +-- messages
¦   ¦   ¦   ¦   ¦  +-- messages-business.properties
¦   +-- pom.xml
+-- project-server-service
¦   +-- src
¦   ¦   +-- main
¦   ¦   ¦   +-- java
¦   ¦   ¦   +-- resources
¦   ¦   ¦   ¦   +-- messages
¦   ¦   ¦   ¦   ¦  +-- messages-business.properties
¦   +-- pom.xml
+-- pom.xml

project B
+-- project-server-business
¦   +-- src
¦   ¦   +-- main
¦   ¦   ¦   +-- java
¦   ¦   ¦   +-- resources
¦   ¦   ¦   ¦   +-- messages
¦   ¦   ¦   ¦   ¦  +-- messages-business.properties
¦   +-- pom.xml
+-- project-server-service
¦   +-- src
¦   ¦   +-- main
¦   ¦   ¦   +-- java
¦   ¦   ¦   +-- resources
¦   ¦   ¦   ¦   +-- messages
¦   ¦   ¦   ¦   ¦  +-- messages-business.properties
¦   +-- pom.xml
+-- pom.xml

My pom build structure:
