Добрый день!
Пытаюсь заставить своё приложение работать со словарём из базы данных, так сказать, сделать его мултиязычным.
Приложение поднимаю с использованием Spring фремворка.
Подскажите, что я делаю не так и как это можно исправить, не работает LocaleResolver и LocaleChangeInterceptor
Вот мой конфиг:
| Код |
@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan("com.sprsec")
@PropertySource("classpath:application.properties")
@ImportResource("classpath:spring-security.xml")
public class WebAppConfig extends WebMvcConfigurerAdapter {
private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "entitymanager.packages.to.scan";
private static final String PROPERTY_NAME_POOL_SIZE = "hibernate.pool_size";
@Resource
private Environment env;
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
return dataSource;
}
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource());
sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
sessionFactoryBean.setHibernateProperties(hibProperties());
return sessionFactoryBean;
}
private Properties hibProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
properties.put(PROPERTY_NAME_POOL_SIZE, env.getRequiredProperty(PROPERTY_NAME_POOL_SIZE));
return properties;
}
@Bean
public HibernateTransactionManager transactionManager() {
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory().getObject());
return transactionManager;
}
@Bean(name = "localeResolver")
public LocaleResolver localeResolver() {
CookieLocaleResolver resolver = new CookieLocaleResolver();
resolver.setDefaultLocale(new Locale("ru"));
return resolver;
}
@Bean(name = "messageSource")
public AbstractMessageSource getMesageSource(){
return new DatabaseMessageSource(sessionFactory().getObject());
}
@Bean
public HandlerInterceptor localeChangeInterceptor(){
LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
localeChangeInterceptor.setParamName("lang");
return localeChangeInterceptor;
}
@Bean(name = "annotationHandlerMapping")
public HandlerMapping handlerMapping() {
final DefaultAnnotationHandlerMapping ret = new DefaultAnnotationHandlerMapping();
ret.setInterceptors(new Object[] { localeChangeInterceptor() });
return ret;
}
@Bean
public UrlBasedViewResolver setupViewResolver() {
UrlBasedViewResolver resolver = new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/pages/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}
}

Уже неделю ломаю голову над проблемой, перекопал весь гугл. Народ в большенстве всё ещё предпочитает пользоваться XML конфигурацией и примеров с аннотациями очень мало. Глядя на XMLы вроде понимаю, какой класс что делает и какие зависимости ему надо, но воплотить это в своём варианте покак никак не удаётся.
На всякий случай привожу код DatabaseMessageSource, малоли кому понадобится:
| Код |
public class DatabaseMessageSource extends AbstractMessageSource {
private final Map<String, Map<String, String>> properties = new HashMap<String, Map<String, String>>();
private SessionFactory sessionFactory;
public DatabaseMessageSource(SessionFactory sessionFactory) {
super();
this.sessionFactory = sessionFactory;
this.setUseCodeAsDefaultMessage(true);
reload();
}
@Override
protected String resolveCodeWithoutArguments(String code, Locale locale) {
return getText(code, locale);
}
@Override
protected MessageFormat resolveCode(String code, Locale locale) {
String msg = getText(code, locale);
MessageFormat result = createMessageFormat(msg, locale);
return result;
}
/**
* @param code
* @param locale
* @return
*/
private String getText(String code, Locale locale) {
Map<String, String> localizedText = properties.get(code);
String textForCurrentLanguage = null;
if (localizedText != null) {
textForCurrentLanguage = localizedText.get(locale.getLanguage());
if (textForCurrentLanguage == null) {
textForCurrentLanguage = localizedText.get(Locale.US.getLanguage());
}
}
return textForCurrentLanguage != null ? textForCurrentLanguage : code;
}
private Map<String, Map<String, String>> refreshProperties() {
properties.clear();
properties.putAll(loadTexts());
return properties;
}
public Session openSession(){
return sessionFactory.openSession();
}
protected Map<String, Map<String, String>> loadTexts() {
Map<String, Map<String, String>> myProp = new HashMap<String, Map<String, String>>();
Query query = openSession().createSQLQuery("select m.code, m.ru, m.lv, m.en from jp_dictionary as m");
Iterator result = query.list().iterator();
while( result.hasNext() ){
Object[] row = (Object[]) result.next();
String code = row[0].toString();
Map<String, String> dataRU = new HashMap<String, String>();
Map<String, String> dataLV = new HashMap<String, String>();
Map<String, String> dataEN = new HashMap<String, String>();
dataRU.put("ru",row[1].toString());
dataLV.put("lv",row[2].toString());
dataEN.put("en",row[3].toString());
myProp.put(code, dataRU);
myProp.put(code, dataLV);
myProp.put(code, dataEN);
}
return myProp;
}
/**
* Reload all codes.
*/
public void reload() {
refreshProperties();
}
}
