Spring MVC 4 java config无法识别本地化更改

Question

这是我的项目结构：

这是Spring root config：

<?php
    $a = 10;
    $b = 'String';

    echo '$a is '.$a;
    echo '....';
    echo '$b is '.$b;

    parse_str("a=$b&b=$a");

    echo '....After Using Parse Str....';

    echo '$a is '.$a;
    echo '....';
    echo '$b is '.$b;

?>

但是当使用@EnableWebMvc @Configuration @ComponentScan({ "com.rgh.*" }) @EnableTransactionManagement @Import({ SpringSecurityConfig.class }) public class SpringWebConfig extends WebMvcConfigurerAdapter { @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/assets/**").addResourceLocations("/assets/"); } // Start localization configs @Bean public MessageSource messageSource() { final ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource(); messageSource.setBasename("classpath:messages"); messageSource.setDefaultEncoding("UTF-8"); return messageSource; } @Bean public LocaleResolver localeResolver() { CookieLocaleResolver localeResolver = new CookieLocaleResolver(); localeResolver.setDefaultLocale(new Locale("fa")); return localeResolver; } @Bean public LocaleChangeInterceptor localeChangeInterceptor() { LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor(); localeChangeInterceptor.setParamName("lang"); return localeChangeInterceptor; } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(localeChangeInterceptor()); } // End localization configs @Bean public SessionFactory sessionFactory() { LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource()); builder.scanPackages("com.rgh.*.model").addProperties(getHibernateProperties()); return builder.buildSessionFactory(); } private Properties getHibernateProperties() { Properties properties = new Properties(); properties.put("hibernate.format.sql", "false"); properties.put("hibernate.show.sql", "true"); properties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect"); properties.put("hibernate.hbm2ddl.auto", "update"); return properties; } @Bean(name = "dataSource") public BasicDataSource dataSource() { BasicDataSource dataSource = new BasicDataSource(); dataSource.setDriverClassName("com.mysql.jdbc.Driver"); dataSource.setUrl("jdbc:mysql://localhost:3306/framework"); dataSource.setUsername("root"); dataSource.setPassword("root"); return dataSource; } @Bean public HibernateTransactionManager txManager() { return new HibernateTransactionManager(sessionFactory()); } @Bean public InternalResourceViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setViewClass(JstlView.class); viewResolver.setPrefix("/view/"); viewResolver.setSuffix(".jsp"); return viewResolver; } } 启动应用程序时，spring无法识别设置为localhost:8080的默认语言环境并使用localeResolver.setDefaultLocale(new Locale("fa"));语言环境加载页面，并且当我使用{调用页面时{1}}它再次加载en_US区域设置的网页。

感谢您的任何想法。

更新

localhost:8080/?lang=de

UPDATE2

这些是我的新配置，默认默认区域设置为en_US且public class SpringWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { @Override protected Class<?>[] getRootConfigClasses() { return new Class[]{SpringWebConfig.class}; } @Override protected Class<?>[] getServletConfigClasses() { return null; } @Override protected String[] getServletMappings() { return new String[]{"/"}; } } 文件未加载，我应该打开登录页面，输入无效的用户名和密码然后按提交，然后将加载en_US并将区域设置更改为messages !!!

messsages_fa.properties

Answer 1

问题是您在根上下文中加载了所有内容，并且没有检测到某些bean。接下来，您应该真正拆分您的配置。创建Web，安全性和持久性配置，并在调度程序servlet的根配置和Web中加载安全性和持久性。

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.rgh"}, excludeFilters = {
    @Filter(org.springframework.stereotype.Controller.class)
})
public class PersistenceConfiguration {

    // Hibernate, transaction manager, datasource and messageSource go here

}

然后是网络配置

@EnableWebMvc
@Configuration
@ComponentScan({ "com.rgh"}, includeFilters = {
    @Filter(org.springframework.stereotype.Controller.class)
}, useDefaultFilters=false )
public class SpringWebConfig extends WebMvcConfigurerAdapter {

    /// web related things like view resolvers, controller, interceptors go here

}

然后在你的bootstrap类中加载正确的配置类。

public class SpringWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{SpringWebSecurity.class, PersistenceConfiguration.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { SpringWebConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

现在您已拆分配置，所有内容都由正确的加载。组件扫描中的includeFilter和excludeFilter以及useDefaultFilters属性在此非常重要，可避免重复bean。如果你不是所有的bean都会被root一次加载一次，而一次由dispatcherservlet加载。
