读取以utf-8编码的ValidationMessages >>

Question

您如何更改验证消息的资源包？默认值是将我的ValidationMessages.properties读取为ISO-8859-1（我想），但它是UTF-8。我试过了：

@Configuration
@EnableWebMvc
@ComponentScan
public class ApplicationConfiguration extends WebMvcConfigurerAdapter{

    @Bean( name = "messageSource" )
    public ReloadableResourceBundleMessageSource validationMessageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("ValidationMessages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Bean
    public LocalValidatorFactoryBean validator() {
        LocalValidatorFactoryBean validatorFactoryBean = new LocalValidatorFactoryBean();
        validatorFactoryBean.setValidationMessageSource(validationMessageSource());
        return validatorFactoryBean;
    }

    @Override
    public Validator getValidator() {
        return validator();
    }
无论我在这里放什么，Hibernate都不使用它来获取消息。有小费吗？我正在使用Hibernate 5和Spring 4。

Answer 1

.properties文件是按ISO-8859-1编码（又称Latin-1。（请参阅https://en.wikipedia.org/wiki/.properties和How to use UTF-8 in resource properties with ResourceBundle）编码按规范读取的。因此，您需要指定unicode字符而不是将文件另存为UTF-8。

    @Bean
    public MessageSource validationMessageResource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename("ValidationMessages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Bean
    public Validator validator() {
        return Validation.byDefaultProvider()
                .configure()
                .messageInterpolator(
                        new ResourceBundleMessageInterpolator(
                                new MessageSourceResourceBundleLocator(validationMessageResource())
                        )
                )
                .buildValidatorFactory()
                .getValidator()
                ;
    }
