我将Spring 4 Hibernate部署到Heroku，使用ClearDB（MySQL）作为数据库。
问题是不能使用波兰语字符，因为它们被替换为“？”。
如果我使用本地数据库在本地运行项目，一切正常。此外，如果我使用MySQL Workbench连接到远程ClearDB，我也可以使用波兰语字符保存，所以我猜问题就在于Hibernate和远程数据库之间。
以下是我的配置文件：
App配置：
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "kamienica.*")
public class AppConfig extends WebMvcConfigurerAdapter {
@Autowired
ReadingEnergyConverter readingEnergyConverter;
@Autowired
ReadingGasConverter readingGasConverter;
@Autowired
ReadingWaterConverter readingWaterConverter;
@Autowired
InvoiceGasConverter invoiceGasConverter;
@Autowired
InvoiceWaterConverter invoiceWaterConverter;
@Autowired
InvoiceEnergyConverter invoiceEnergyConverter;
@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
configurer.ignoreAcceptHeader(true).defaultContentType(MediaType.TEXT_HTML);
}
/*
* Configure ContentNegotiatingViewResolver
*/
@Bean
public ViewResolver contentNegotiatingViewResolver(ContentNegotiationManager manager) {
ContentNegotiatingViewResolver resolver = new ContentNegotiatingViewResolver();
resolver.setContentNegotiationManager(manager);
// Define all possible view resolvers
List<ViewResolver> resolvers = new ArrayList<ViewResolver>();
resolvers.add(jsonViewResolver());
resolvers.add(viewResolver());
resolver.setViewResolvers(resolvers);
return resolver;
}
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
// viewResolver.setContentType("UTF-8");
return viewResolver;
}
// @Bean
// public LocaleResolver localeResolver() {
// SessionLocaleResolver localeResolver = new SessionLocaleResolver();
// localeResolver.setDefaultLocale(Locale.ENGLISH); // change this
// return localeResolver;
// }
//
//
// @Override
// public void addInterceptors(InterceptorRegistry registry) {
// registry.addInterceptor(localeChangeInterceptor());
// }
//
// @Bean
// public LocaleChangeInterceptor localeChangeInterceptor(){
// LocaleChangeInterceptor localeChangeInterceptor=new LocaleChangeInterceptor();
// localeChangeInterceptor.setParamName("language");
// return localeChangeInterceptor;
// }
@Bean(name = "localeResolver")
public LocaleResolver getLocaleResolver(){
return new CookieLocaleResolver();
}
@Bean
public ViewResolver jsonViewResolver() {
return new JsonViewResolver();
}
@Override
public void addFormatters(FormatterRegistry registry) {
registry.addConverter(readingEnergyConverter);
registry.addConverter(readingGasConverter);
registry.addConverter(readingWaterConverter);
registry.addConverter(invoiceEnergyConverter);
registry.addConverter(invoiceGasConverter);
registry.addConverter(invoiceWaterConverter);
}
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("/static/");
}
}
Hibernate配置：
@Configuration
@EnableTransactionManagement
@ComponentScan({ "kamienica.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {
@Autowired(required=false)
private Environment environment;
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { "kamienica.model" });
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
}
private Properties hibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
properties.put("hibernate.connection.characterEncoding", environment.getRequiredProperty("hibernate.connection.characterEncoding"));
properties.put("hibernate.connection.charSet", environment.getRequiredProperty("hibernate.connection.charSet"));
return properties;
}
@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(s);
return txManager;
}
Hibernate的资源：
jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://**************
jdbc.username = **************
jdbc.password = *******************
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto=update
hibernate.current_session_context_class=thread
hibernate.connection.characterEncoding=UTF-8
hibernate.connection.charSet=UTF-8
