@Configuration
public class MvcConfiguration extends WebMvcConfigurationSupport {

    @Bean(name = "messageSource")
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messages = new ReloadableResourceBundleMessageSource();
        messages.setBasenames("classpath:beanValidation", "classpath:errors");
        messages.setDefaultEncoding("UTF-8");
        return messages;
    }

    @Override
    protected Validator getValidator() {
        LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
        validator.setValidationMessageSource(messageSource());
        return validator;
    }
}

当我将messageSource方法重命名为messageSource2时，它可以工作，但我不太会使用自带默认messageSource的LocalizedMessageService来查询自定义消息。

如何将自定义消息基名称添加到默认消息源？

Answer 1

解决了。

我已经将messageSource bean与MvcConfiguration分离，并将其放在另一个configuration类中：

@Configuration
public class LocalizationConfiguration {

    @Bean
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messages = new ReloadableResourceBundleMessageSource();
        messages.setBasenames("classpath:beanValidation", "classpath:errors");
        messages.setDefaultEncoding("UTF-8");
        return messages;
    }

}

另外，我的WebMvcConfigurationSupport扩展无法实例化MessageSource。
