I'm trying to test a internationalization but I keep getting the message "No message found under code 'good.morning.message' for locale 'us'." each time I make a GET request.
I'm using Netbeans IDE for my project. Below are my codes
#SpringBootApplication
public class RestfulWebServicesApplication {
public static void main(String[] args) {
SpringApplication.run(RestfulWebServicesApplication.class, args);
}
#Bean
public LocaleResolver localeResolver() {
SessionLocaleResolver localeResolver = new SessionLocaleResolver();
localeResolver.setDefaultLocale(Locale.US);
return localeResolver;
}
#Bean
public ReloadableResourceBundleMessageSource bundleMessageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
ControllerClass
#RestController
public class HelloWorldController {
#Autowired
private MessageSource messageSource;
#GetMapping("/hello-world-internationalized")
public String helloWorldInternationalized(#RequestHeader(name="Accept-Language", required=false) Locale locale) {
return messageSource.getMessage("good.morning.message", null, locale);
//return "Good morning";
}
}
Here's my messages.properties file:
good.morning.message=Good Morning
And here's the link to my folder structure
Change bundleMessageSource() name to messageSource().

I'm having properties/messages file name:
messages_en.properties
And I have the property inside:
country.AF.name=Afghanistan
here is the messages class:
#ApplicationScope
#Configuration
#Slf4j
public class Messages {
private ResourceBundleMessageSource messageSource;
private MessageSourceAccessor accessor;
#PostConstruct
private void init() {
messageSource();
accessor = new MessageSourceAccessor(messageSource, Locale.ENGLISH);
log.info("Messages initialized");
}
public String get(String code) {
return accessor.getMessage(code);
}
public void messageSource() {
messageSource = new ResourceBundleMessageSource();
messageSource.setBasenames("classpath:messages_en.properties");
messageSource.setUseCodeAsDefaultMessage(true);
}
The full error I'm getting is as follow:
at com.fasterxml.jackson.databind.ser.std.BeanSerializerBase.serializeFields(BeanSerializerBase.java:770) ~[jackson-databind-2.12.3.jar:2.12.3]
Postman show wrong results, I need to get all the countries:
Did you add the below things message Sources bean configuration
messageSource
.setBasename("classpath:messages_en.properties")
I've a Spring Boot 2.4.2 REST application using JPA, Hibernate, etc.
So far I use a MessageSource for applications errors (located in i18n/messages), and the default ValidationMessagesfor bean validations.
This is part of my configuration:
public static Set<Locale> LOCALES = Set.of(new Locale("en"), new Locale("it"));
#Bean
public LocaleResolver localeResolver() {
SmartLocaleResolver localeResolver = new SmartLocaleResolver();
return localeResolver;
}
public class SmartLocaleResolver extends AcceptHeaderLocaleResolver {
#Override
public Locale resolveLocale(HttpServletRequest request) {
if (StringUtils.isBlank(request.getHeader("Accept-Language"))) {
return Locale.getDefault();
}
List<Locale.LanguageRange> list = Locale.LanguageRange.parse(request.getHeader("Accept-Language"));
Locale locale = Locale.lookup(list, LOCALES);
return locale;
}
}
#Primary
#Bean("messageSource")
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setAlwaysUseMessageFormat(true);
messageSource.setBasenames("classpath:/i18n/messages");
// set to true only for debugging
messageSource.setUseCodeAsDefaultMessage(false);
messageSource.setFallbackToSystemLocale(false);
return messageSource;
}
My application supports 2 languages so far: it and en.
The problem right now is that application's messages are correctly localized in the agent's language (browser) but Validations errors are not.
I found out that Hibernate uses the default locale (Locale.getDefault()) and to customize the behaviour I should customize the locale resolution.
So I tried creating a custom hibernateValidator (that I set in my entityFactory) :
#Bean
public MessageSource validationMessageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setAlwaysUseMessageFormat(true);
messageSource.setBasenames("classpath:/ValidationMessages");
// set to true only for debugging
messageSource.setUseCodeAsDefaultMessage(false);
messageSource.setFallbackToSystemLocale(false);
return messageSource;
}
#Bean("hibernateValidator")
public LocalValidatorFactoryBean hibernateValidator() {
LocalValidatorFactoryBean factoryBean = new LocalValidatorFactoryBean();
factoryBean.setValidationMessageSource(validationMessageSource());
return factoryBean;
}
and the resolver:
public class HibernateLocaleResolver implements LocaleResolver {
#Override
public Locale resolve(LocaleResolverContext context) {
return LocaleContextHolder.getLocale();
}
}
Doing this, the locale resolution works fine, but the parameter replacement doesn't. What I mean is for messages like this:
server.validators.ArraySize.message = The number of values must be between [{min}] and [{max}].
I've an exception:
"exception": "java.lang.IllegalArgumentException", "message": "can't parse argument number: min"
So I changed the configuration above adding the MessageInterpolator:
factoryBean.setMessageInterpolator(new ResourceBundleMessageInterpolator(LOCALES, Locale.ENGLISH, new HibernateLocaleResolver(), false));
At this point the parameters are resolved correctly, but again the locale resolution doesn't work.
Can you point me out in the right direction, trying to explain the best practice to follow for the combination Spring Boot - Hibernate Validator?
I solved the problem. I hope this can help someone else. This is my configuration file:
#Primary
#Bean("messageSource")
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setAlwaysUseMessageFormat(true);
messageSource.setBasenames("classpath:/i18n/messages");
// set to true only for debugging
messageSource.setUseCodeAsDefaultMessage(false);
messageSource.setFallbackToSystemLocale(false);
return messageSource;
}
#Bean
public MessageSource validationMessageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setAlwaysUseMessageFormat(true);
messageSource.setBasenames("classpath:/ValidationMessages");
// set to true only for debugging
messageSource.setUseCodeAsDefaultMessage(false);
messageSource.setFallbackToSystemLocale(false);
return messageSource;
}
#Bean
public LocalValidatorFactoryBean validator() {
LocalValidatorFactoryBean factoryBean = new LocalValidatorFactoryBean();
factoryBean.setValidationMessageSource(validationMessageSource());
MessageInterpolatorFactory interpolatorFactory = new MessageInterpolatorFactory();
factoryBean.setMessageInterpolator(interpolatorFactory.getObject());
return factoryBean;
}
and the LocaleConfiguration:
#Configuration
public class LocaleConfiguration implements WebMvcConfigurer {
#Bean
public LocaleResolver localeResolver() {
SmartLocaleResolver localeResolver = new SmartLocaleResolver();
return localeResolver;
}
public class SmartLocaleResolver extends AcceptHeaderLocaleResolver {
#Override
public Locale resolveLocale(HttpServletRequest request) {
if (StringUtils.isBlank(request.getHeader("Accept-Language"))) {
return Locale.getDefault();
}
List<Locale.LanguageRange> list = Locale.LanguageRange.parse(request.getHeader("Accept-Language"));
Locale locale = Locale.lookup(list, Constants.LOCALES);
return locale;
}
}
}
the important part I saw made the difference are these lines:
MessageInterpolatorFactory interpolatorFactory = new MessageInterpolatorFactory();
factoryBean.setMessageInterpolator(interpolatorFactory.getObject());
In this way the interpolator works fine as well as the localization of the message.
Do we have anyway where we can define one property is dependent on the other property?
messages.properties
product.name=XYZ
product.title=XYZ title
I have already tried the below one but its not working
product.name=XYZ
product.title=${product.name} title
#Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource =
new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:messages");
messageSource.setDefaultEncoding("UTF-8");
return messageSource;
}
#Component
public class Messages {
#Autowired
private MessageSource messageSource;
private MessageSourceAccessor accessor;
#PostConstruct
private void init() {
accessor = new MessageSourceAccessor(messageSource);
}
public String get(String code, #Nullable Object[] args) {
return accessor.getMessage(code, args);
}
public String get(String code) {
return accessor.getMessage(code);
}
}
I'm using Spring Boot 1.5.8, Spring Data REST, Spring HATEOAS. In my application exposing REST endpoints I enabled:
spring.data.rest.enable-enum-translation=true
In this way when I ask for an enum it is translated acconding to my locale.
Some more configuration stuff:
#Bean
public LocaleResolver localeResolver() {
return new SmartLocaleResolver();
}
public class SmartLocaleResolver extends CookieLocaleResolver {
#Override
public Locale resolveLocale(HttpServletRequest request) {
String acceptLanguage = request.getHeader("Accept-Language");
if (acceptLanguage == null || acceptLanguage.trim().isEmpty()) {
return super.determineDefaultLocale(request);
}
return request.getLocale();
}
}
#Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasenames("classpath:/i18n/messages");
// messageSource.setDefaultEncoding("UTF-8");
// set to true only for debugging
messageSource.setUseCodeAsDefaultMessage(false);
messageSource.setCacheSeconds((int) TimeUnit.HOURS.toSeconds(1));
messageSource.setFallbackToSystemLocale(false);
return messageSource;
}
#Bean
public MessageSourceAccessor messageSourceAccessor() {
return new MessageSourceAccessor(messageSource());
}
As you can see I set also message source in order to translate also exceptions coming from the server.
My server locale is it-IT and I've rest-messages.properties (US translation) and rest-messages_it.properties (IT translation). My goal is to use rest-messages.properties when the language is not recognized and rest-messages_it.properties when the language is IT.
Right now it doesn't work. Spring Data REST read rest-messages_it.properties when there isn't a corrispondent file for the language selected.
I solved this problem with messages.properties using messageSource.setFallbackToSystemLocale(false);. Is there a way to do the same thing for rest-messages files?
What if you subclass the RepositoryRestMvcConfiguration, override and copy its method resourceDescriptionMessageSourceAccessor, but set fallbackToSystemLocale to false for messageSource?
#Override
#Bean
public MessageSourceAccessor resourceDescriptionMessageSourceAccessor() {
try {
PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
propertiesFactoryBean.setLocation(new ClassPathResource("rest-default-messages.properties"));
propertiesFactoryBean.afterPropertiesSet();
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:rest-messages");
messageSource.setCommonMessages(propertiesFactoryBean.getObject());
messageSource.setDefaultEncoding("UTF-8");
// Adding this line:
messageSource.setFallbackToSystemLocale(false);
return new MessageSourceAccessor(messageSource);
} catch (Exception o_O) {
throw new BeanCreationException("resourceDescriptionMessageSourceAccessor", "", o_O);
}
}
And what if you create the rest-default-messages.properties file with values for the default locale?..
Update from the question author
To preserve spring.data.rest.* properties it's necessary to create a RepositoryRestConfiguration Bean as described in this post:
#Bean
#ConfigurationProperties(prefix = "spring.data.rest")
#Override
public RepositoryRestConfiguration config() {
return super.config();
}
I'm trying to override the ValidationMessages.properties from default hibernate-validation (5.0.2 version) in a Spring MVC application.
But it keeps using the internal ValidationMessages.properties from jar.
UPDATE: it works (but it should be another way) when I copy the *.properties files to org\hibernate\validator ...
This is my configuration:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"com.blueliv.search.*"} )
public class WebConfig extends WebMvcConfigurerAdapter {
static Logger log =LoggerFactory.getLogger(WebMvcConfigurerAdapter.class);
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(new GsonHttpMessageConverter());
//converters.add(new MappingJackson2HttpMessageConverter());
}
#Bean
public MethodValidationPostProcessor methodValidationPostProcessor() {
return new MethodValidationPostProcessor();
}
#Bean
public ExceptionHandlerExceptionResolver exceptionResolver() {
return new ExceptionHandlerExceptionResolver();
}
#Bean
public LocalValidatorFactoryBean validator() {
LocalValidatorFactoryBean validatorFactoryBean = new LocalValidatorFactoryBean();
validatorFactoryBean.setValidationMessageSource(getBundle());
return validatorFactoryBean;
}
public ReloadableResourceBundleMessageSource getBundle(){
log.debug("get bundle!");
ReloadableResourceBundleMessageSource bundle = new ReloadableResourceBundleMessageSource();
bundle.setBasenames("classpath:/i18n/validation/ValidatonMessages");
return bundle;
}
#Override
public Validator getValidator() {
return validator();
}
