Character-encoding Spring MVC - spring-mvc

Question

I am having trouble with Turkish characters...In my JSP pages, there is no problem... but, when an alert come from Java side, Turkish character(ŞşİığĞüÜç...) seems like that (ı,?,ü,ç,Å,...)
In JSP pages, I use this code and ı can solve Turkish character problem
<%# page contentType="text/html;charset=UTF-8" language="java"%>
in Spring MVC config, I tried a lot of way but I didn't succeed... For example In my mvc config class, I set my MessageSource like that;
#Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:messages");
messageSource.setUseCodeAsDefaultMessage(true);
messageSource.setDefaultEncoding("UTF-8");
messageSource.setCacheSeconds(0);
return messageSource;
}
In this program, I try to reset password and I typed unregister email address..Finally I am getting exception and this following is exception code blog.
#Autowired
private MessageSource messages;
...
#ExceptionHandler({ UserNotFoundException.class })
public ResponseEntity<Object> handleUserNotFound(final RuntimeException exception, final WebRequest request) {
logger.error("404 Status Code", exception);
final GenericResponse bodyOfResponse = new GenericResponse(messages.getMessage("message.userNotFound", null, request.getLocale()), "UserNotFound");
return handleExceptionInternal(exception, bodyOfResponse, new HttpHeaders(), HttpStatus.NOT_FOUND, request);
}
In my messages_tr_TR.properties file,
...
message.userNotFound=Kullanıcı Bulunamadı
...
but In JSP pages this alert shows like that;
Kullanıcı Bulunamadı
How can I solve this problem..

Answer 1

Comment follow-up, you can set the encoding in your response header as well. An example if you're returning json would be
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.add("Content-Type", "application/json; charset=utf-8");
return handleExceptionInternal(exception, responseHeaders, HttpStatus.NOT_FOUND, request);

In web.xml:
<jsp-config>
<!-- global JSP configuration -->
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config>
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Put the actual text in the handler method (temporarily). Does it now look right? Is your messages file correctly saved as UTF-8? Also, I can't tell if you're using JSON or not...
