我已将经典的spring框架应用程序转换为Spring Boot，现在我得到了这个：

@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 ，它可以正常工作，但我无法使用我的LocalizedMessageService自动assembly默认的MessageSource来查询我的自定义消息。
如何将自定义消息库名称添加到默认MessageSource？
解决了。
我已将messageSource bean与MvcConfiguration分开 ，我把它放在另一个配置类中：
@Configuration public class LocalizationConfiguration { @Bean public MessageSource messageSource() { ReloadableResourceBundleMessageSource messages = new ReloadableResourceBundleMessageSource(); messages.setBasenames("classpath:beanValidation", "classpath:errors"); messages.setDefaultEncoding("UTF-8"); return messages; } }
显然，我的WebMvcConfigurationSupport扩展无法实例化messageSource。
