spring boot - How to access properties from dependent jar -

i've core project handles common concerns , applies aspects, called "common ". service projects uses core project common processes.

i have manage exception handling in "common " , have read messages properties file in common. services can have custom messages too.

so put messageutils in common

messageutils.java @component public class messageutils {    @autowired    private messagesource messagesource;     private static messagesourceaccessor accessor;      @postconstruct    private void init() {        accessor = new messagesourceaccessor(messagesource, locale.english);    }     public static string getmessage(string messagekey) {        return accessor.getmessage(messagekey);     } 

}

in common, have common-messages.properties

 |-src/main/resources     |--common-messages_en.properties 

lets service named service_1 depends common.

service_1 have service-messages_en.properties

|-src/main/resources     |--service-messages_en.properties 

to inject common specific configurations i've declared config class in common , imported in service's spring boot initializer class. defined "common-messages_en.properties" property source in commonconfig.

commonconfig.java

@componentscan({ "com.example.common.core"}) @entityscan({ "com.example.common.entity" }) @enablejparepositories(basepackages = { "com.example.common.dao" }) @propertysource(value = { "classpath:common-messages_en.properties"}) public class commonconfig {  } 

so, in service_1 i've bootapp class starts springboot app. commonconfig imported there.

@springbootapplication @import(commonconfig.class) public class bootapp extends springbootservletinitializer {      public static void main(string[] args) {         springapplication.run(bootapp.class, args);     } } 

when call

messageutils.getmessage("somemessagekey.thatdefinedin.service");  

it's ok, can read service's messages.

but when want read common message in service;

messageutils.getmessage("somemessagekey.thatdefinedin.common");  

it gets nosuchmessageexception.

how can merge different property files in different jars ?

ok. when initalize reloadableresourcebundlemessageresource while booting that;

 @bean  public reloadableresourcebundlemessagesource messagesource() {    reloadableresourcebundlemessagesource messagesource = new     reloadableresourcebundlemessagesource();     messagesource.setbasenames("classpath:service-messages","classpath:common-messages");    messagesource.setcacheseconds(3600); //refresh cache once per hour    return messagesource;  } 

(supposing default locale "en") can access both common , service messages @ runtime.
