Internationalization in Spring

I have a springBoot 2.4.0 app, with this piece of code in the controller:

String defaultLocation =
                messages.getMessage("home.default.location", null, LocaleContextHolder.getLocale());

In the application I see the messages from the properties loaded correctly with the messages, and no error, but in the log I see this error:

14:43:41.168 [http-nio-7080-exec-13] WARN  o.s.c.s.ReloadableResourceBundleMessageSource.refreshProperties 445 - Could not parse properties file [messages_en.properties]

this is my config class:

@Configuration
public class I18NConfig {

    private final Environment env;

    public I18NConfig(Environment env) {
        this.env = env;
    }

    @Bean
    @Qualifier("messageSource")
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource resourceBundleMessageSource = new ReloadableResourceBundleMessageSource();

        
            resourceBundleMessageSource.setBasename("classpath:i18n/messages");
        

        resourceBundleMessageSource.setDefaultEncoding("UTF-8"); // Set the UTF-8 encoding
        resourceBundleMessageSource.setCacheSeconds(1);
        return resourceBundleMessageSource;
    }
}

use

org.springframework.context.support.ReloadableResourceBundleMessageSource

instead of

org.springframework.context.support.ResourceBundleMessageSource

configuration like this:

   <bean name="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> 
    <property name="basename"> 
        <value>classpath*:i18n/messages</value> 
    </property> 
</bean>

or this:

 @Bean
 public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("classpath:i18n/messages");
        messageSource.setCacheSeconds(10); //reload messages every 10 seconds
        return messageSource;
  }

Change in your bean definition like this ...remove cache seconds and use setUSeCodeAsDefaultMessage() and give it a try.Also recheck you properties file definitions and naming references.

@Bean
    @Qualifier("messageSource")
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource resourceBundleMessageSource = new ReloadableResourceBundleMessageSource();

        
            resourceBundleMessageSource.setBasename("classpath:i18n/messages");
        

        resourceBundleMessageSource.setDefaultEncoding("UTF-8"); 
        resourceBundleMessageSource.setUseCodeAsDefaultMessage(true);
        return resourceBundleMessageSource;
    }
