彈簧4 MVC地點更改，但JSP不適用於本

初始化程序：

public class Initializer implements WebApplicationInitializer { 

    private static final String DISPATCHER_SERVLET_NAME = "dispatcher"; 

    @Override 
    public void onStartup(ServletContext servletContext) throws ServletException { 
     AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); 

     ctx.register(ApplicationConfig.class); 

     servletContext.addListener(new ContextLoaderListener(ctx)); 
     servletContext.setInitParameter("defaultHtmlEscape", "true"); 
     servletContext.addListener(new HttpSessionEventPublisher()); 
     servletContext.addListener(new RequestContextListener()); 

     FilterRegistration.Dynamic fr = servletContext.addFilter("encodingFilter", 
       new CharacterEncodingFilter()); 
     fr.setInitParameter("encoding", "UTF-8"); 
     fr.setInitParameter("forceEncoding", "true"); 
     fr.addMappingForUrlPatterns(null, true, "/*"); 

     servletContext.addFilter("securityFilter", new DelegatingFilterProxy("springSecurityFilterChain")) 
       .addMappingForUrlPatterns(null, false, "/*"); 

     ServletRegistration.Dynamic servlet = servletContext.addServlet(DISPATCHER_SERVLET_NAME, 
       new DispatcherServlet(ctx)); 
     servlet.addMapping("/"); 
     servlet.setLoadOnStartup(1); 
     servlet.setAsyncSupported(true); 

     ctx.setServletContext(servletContext); 
    } 

    public Filter[] getServletFilters() { 

     CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter(); 
     characterEncodingFilter.setEncoding("UTF-8"); 
     characterEncodingFilter.setForceEncoding(true); 

     return new Filter[]{characterEncodingFilter, new DelegatingFilterProxy()}; 
    } 

}

ApplicationConfig：

@Configuration 
@EnableWebMvc 
@ComponentScan("com.example.*") 
@PropertySource("classpath:app.properties") 
public class ApplicationConfig extends WebMvcConfigurerAdapter { 

    private static final Charset UTF8 = Charset.forName("UTF-8"); 

    @Override 
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
     configurer.enable(); 
    } 

    @Override 
    public void addInterceptors(InterceptorRegistry registry) { 
     OpenSessionInViewInterceptor sessionInViewInterceptor = new OpenSessionInViewInterceptor(); 
     sessionInViewInterceptor.setSessionFactory(sessionFactory); 

     registry.addWebRequestInterceptor(sessionInViewInterceptor); 
     registry.addInterceptor(localeChangeInterceptor()); 
    } 

    @Bean 
    public InternalResourceViewResolver getInternalResourceViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/pages/"); 
     resolver.setSuffix(".jsp"); 
     resolver.setViewClass(JstlView.class); 
     return resolver; 
    } 

    @Bean 
    public MessageSource messageSource() { 
     ReloadableResourceBundleMessageSource ret = new ReloadableResourceBundleMessageSource(); 
     ret.setBasenames("classpath:messages", "classpath:labels", "classpath:exceptions"); 
     ret.setDefaultEncoding(UTF8.name()); 
     return ret; 
    } 

// @Bean 
// public SessionLocaleResolver localeResolver() { 
//  // TODO locale 
//  Locale ruLocale = new Locale.Builder().setLanguage("ru").build(); 
//  SessionLocaleResolver localeResolver = new SessionLocaleResolver(); 
//  localeResolver.setDefaultLocale(ruLocale); 
//  return localeResolver; 
// } 

    @Bean 
    public CookieLocaleResolver localeResolver() { 
     CookieLocaleResolver cookieLocaleResolver = new CookieLocaleResolver(); 
     cookieLocaleResolver.setCookieName("localceCookie"); 
     cookieLocaleResolver.setCookieMaxAge(3600); 

     return cookieLocaleResolver; 
    } 

    @Bean 
    public LocaleChangeInterceptor localeChangeInterceptor() { 
     LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor(); 
     localeChangeInterceptor.setParamName("locale"); 
     return localeChangeInterceptor; 
    } 

}

所以我有LocaleChangeInterceptor，CookieLocaleResolver的， MessageSource的。我有labels.properties和labels_en.properties。

JSP：

Language : <a href="?locale=en">English</a>|<a href="?locale=ru">Russian</a> 

<h2> 
    lable.testLocale : <spring:message code="lable.testLocale" text="default text" /> 
</h2> 

Current Locale : ${pageContext.response.locale}

當我點擊鏈接打開英語，俄語，JSP重載和當前locale值在JSP顯示俄語和英語（取決於鏈接）。所以語言環境更改成功。出現名稱爲localceCookie的Cookie，它包含ru或en值取決於所選語言環境，但JSP值label.testLocale僅顯示en語言環境的值，並且不會更改。我查了很多問題，其中大部分都是關於localeInterceptor的。

我嘗試了Tomcat，Jetty，JBoss（現在是野蠻）應用服務器。我嘗試了不同的瀏覽器。另外，我發現this tutorial，項目不起作用，我爲控制器做了一些類似@RequestMapping的更改，但區域設置在此示例中不起作用。

UPDATE＃1

因此到@TechBreak的答案i執行以下操作： 1.改變束的基本名稱，並設置默認語言環境中CookieLocaleResolver的

@Bean 
public MessageSource messageSource() { 
    ReloadableResourceBundleMessageSource ret = new ReloadableResourceBundleMessageSource(); 
    ret.setBasenames("/WEB-INF/messages", "/WEB-INF/labels", "/WEB-INF/exceptions"); 
    ret.setDefaultEncoding(UTF8.name()); 
    return ret; 
} 
@Bean 
public CookieLocaleResolver localeResolver() { 
    Locale ruLocale = new Locale.Builder().setLanguage("ru").build(); 
    CookieLocaleResolver cookieLocaleResolver = new CookieLocaleResolver(); 
    cookieLocaleResolver.setDefaultLocale(ruLocale); 
    cookieLocaleResolver.setCookieName("localceCookie"); 
    cookieLocaleResolver.setCookieMaxAge(3600); 
    return cookieLocaleResolver; 
}

移動到/ WEB-INF/

問題依然存在。

更新＃2

現在我的配置是這樣的：

@Configuration 
@EnableWebMvc 
@ComponentScan("com.example.*") 
@PropertySource("classpath:app.properties") 
public class ApplicationConfig extends WebMvcConfigurerAdapter { 

    @Autowired 
    private SessionFactory sessionFactory; 

    private static final Charset UTF8 = Charset.forName("UTF-8"); 

    @Bean 
    public static PropertySourcesPlaceholderConfigurer propertiesBean() { 
     return new PropertySourcesPlaceholderConfigurer(); 
    } 

    @Override 
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
     configurer.enable(); 
    } 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     registry.addResourceHandler("/assets/**").addResourceLocations("/assets/").setCachePeriod(31556926); 
     registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(31556926); 
     registry.addResourceHandler("/img/**").addResourceLocations("/img/").setCachePeriod(31556926); 
     registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926); 
    } 

    @Bean 
    public RequestMappingHandlerMapping handlerMapping() { 
     RequestMappingHandlerMapping handlerMapping = new RequestMappingHandlerMapping(); 
     handlerMapping.setInterceptors(localeChangeInterceptor()); 
     return handlerMapping; 
    } 

    @Override 
    public void addInterceptors(InterceptorRegistry registry) { 
     OpenSessionInViewInterceptor sessionInViewInterceptor = new OpenSessionInViewInterceptor(); 
     sessionInViewInterceptor.setSessionFactory(sessionFactory); 

//  registry.addWebRequestInterceptor(sessionInViewInterceptor); 
     registry.addInterceptor(localeChangeInterceptor()); 
    } 


// @Bean 
// public SimpleControllerHandlerAdapter simpleControllerHandlerAdapter() { 
//  return new SimpleControllerHandlerAdapter(); 
// } 

    @Bean 
    public InternalResourceViewResolver getInternalResourceViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/pages/"); 
     resolver.setSuffix(".jsp"); 
     resolver.setViewClass(JstlView.class); 
     return resolver; 
    } 

    @Bean 
    public MessageSource messageSource() { 
     ReloadableResourceBundleMessageSource ret = new ReloadableResourceBundleMessageSource(); 
     ret.setBasenames("/WEB-INF/labels"); 
     ret.setDefaultEncoding(UTF8.name()); 
     return ret; 
    } 

// @Bean 
// public SessionLocaleResolver localeResolver() { 
//  // TODO locale 
//  Locale ruLocale = new Locale.Builder().setLanguage("ru").build(); 
//  SessionLocaleResolver localeResolver = new SessionLocaleResolver(); 
//  localeResolver.setDefaultLocale(ruLocale); 
//  return localeResolver; 
// } 

    @Bean 
    public CookieLocaleResolver localeResolver() { 
     Locale ruLocale = new Locale.Builder().setLanguage("ru").build(); 
     CookieLocaleResolver cookieLocaleResolver = new CookieLocaleResolver(); 
     cookieLocaleResolver.setDefaultLocale(ruLocale); 
     cookieLocaleResolver.setCookieName("localceCookie"); 
     cookieLocaleResolver.setCookieMaxAge(3600); 

     return cookieLocaleResolver; 
    } 

    @Bean 
    public LocaleChangeInterceptor localeChangeInterceptor() { 
     // TODO locale 
     LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor(); 
     localeChangeInterceptor.setParamName("locale"); 
     localeChangeInterceptor.setHttpMethods(HttpMethod.GET.name(), HttpMethod.POST.name()); 
     return localeChangeInterceptor; 
    } 
}

我嘗試DefaultAnnotationHandlerMapping，但它已被棄用，Spring says to useRequestMappingHandlerMapping，在這兩種情況下，問題依然存在。在label.properties我有俄語，它是默認的語言環境，在label_en.properites英語語言。俄語區域設置爲默認語言環境。

最終配置

這是在配置

@Bean 
public RequestMappingHandlerMapping handlerMapping() { 
    RequestMappingHandlerMapping handlerMapping = new RequestMappingHandlerMapping(); 
    handlerMapping.setInterceptors(localeChangeInterceptor()); 
    return handlerMapping; 
}

的重要組成部分，爲默認的locale我做labels_ru.properties和英語語言環境中我做了labels.properties。

其中是您的labels_ru.properties？在它缺席的情況下，它將用於默認屬性文件。 – ScanQR

src/main/Java/resources – dikkini

它不應該在java下。它應該位於java資源目錄中。 – ScanQR

當你是你使用

ReloadableResourceBundleMessageSource

，那麼你必須從當前src/main/resources移動你的資源包文件資源的WEB-INF的目錄。

請閱讀文檔：http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/context/support/ReloadableResourceBundleMessageSource.html

它說，可以重新加載它們應該被投入WEB-INF目錄。

我也看到，你需要做以下的配置等同，

<bean id="handlerMapping" 
     class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"> 
     <property name="interceptors"> 
      <ref bean="localeChangeInterceptor" /> 
     </property> 
    </bean>

編輯：另外，還要確保你有label_ru.properties文件中定義。

它沒有幫助。請檢查我的問題，我更新它。 – dikkini

@dikkini你可以先嚐試單個基名嗎？ ret.setBasenames（「/ WEB-INF /標籤」）; – ScanQR

我很困惑爲什麼你添加了本地攔截器到hibernate相關的http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/orm/hibernate3/support/OpenSessionInViewInterceptor.html – ScanQR
