一台Apache Tomcat应用程序服务器，具有2个配置的war应用程序和一个MessageSource异常

Question

I have an Apache Tomcat application server, version 8.5.30, and it has 2 web applications configured on it.

These applications have Spring Framework 5 and each one has its own ReloadableResourceBundleMessageSource because I use internationalization of messages (i18n).

When I start Apache and load one of the sites, the site that was opened first has its messages loaded into memory, and the second site when I open doesn't have its messages loaded. So this causes an exception message on second application and throws an exception like:

Caused by: org.springframework.context.NoSuchMessageException : No message found under code 'menu.login' for locale 'en_US'.

To try to solve this problem, I tried to create two different MessagesSources, one for each application, but when loading the application server another exception was thrown:

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.context.MessageSource] is defined: expected single matching bean but found 2: messageSourceA, messageSourceB.

Some example about how I tried to do

AppA in ROOT.war (alias 1)

@Bean
public MessageSource messageSourceA() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("classpath*:messageA", "classpath*:enumaratorA");
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

AppB in ROOT.war (alias 2)

@Bean
public MessageSource messageSourceB() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("classpath*:messageB", "classpath*:enumaratorB");
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

Please, could you help me to solve this problem?
How can I make the Apache/Spring understand that they are two different sources?
What other options can be made?

Thanks in advance.

I would suggest to try for this to work.

Assuming properties files are stored at project's src/main/resources package. Please remove file suffix .properties so that only messageB and enumeratorB remains in messageSource.setBasenames("classpath:messageB", "classpath:enumaratorB"); and double check file path and spelling.

If your properties files are in classpath, please use classpath*: otherwise Spring will look for properties in web directory of your application.
