Question

我有一个springBoot 2.4.0应用程序，在控制器中有这段代码:

String defaultLocation =
messages.getMessage("home.default.location", null, LocaleContextHolder.getLocale());

在应用程序中，我看到来自属性的消息正确加载了消息，没有错误，但在日志中我看到这个错误:

14:43:41.168 [http-nio-7080-exec-13] WARN  o.s.c.s.ReloadableResourceBundleMessageSource.refreshProperties 445 - Could not parse properties file [messages_en.properties]

这是我的配置类:

@Configuration
public class I18NConfig {
private final Environment env;
public I18NConfig(Environment env) {
this.env = env;
}
@Bean
@Qualifier("messageSource")
public ReloadableResourceBundleMessageSource messageSource() {
ReloadableResourceBundleMessageSource resourceBundleMessageSource = new ReloadableResourceBundleMessageSource();

resourceBundleMessageSource.setBasename("classpath:i18n/messages");

resourceBundleMessageSource.setDefaultEncoding("UTF-8"); // Set the UTF-8 encoding
resourceBundleMessageSource.setCacheSeconds(1);
return resourceBundleMessageSource;
}
}

Answer 1

像这样更改bean定义…删除缓存秒并使用setUSeCodeAsDefaultMessage()并尝试一下。还要重新检查您的属性文件定义和命名引用。

@Bean
@Qualifier("messageSource")
public ReloadableResourceBundleMessageSource messageSource() {
ReloadableResourceBundleMessageSource resourceBundleMessageSource = new ReloadableResourceBundleMessageSource();

resourceBundleMessageSource.setBasename("classpath:i18n/messages");

resourceBundleMessageSource.setDefaultEncoding("UTF-8"); 
resourceBundleMessageSource.setUseCodeAsDefaultMessage(true);
return resourceBundleMessageSource;
}

Answer 2

use

org.springframework.context.support.ReloadableResourceBundleMessageSource

不是

org.springframework.context.support.ResourceBundleMessageSource

配置如下:

<bean name="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> 
<property name="basename"> 
<value>classpath*:i18n/messages</value> 
</property> 
</bean>

或:

@Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:i18n/messages");
messageSource.setCacheSeconds(10); //reload messages every 10 seconds
return messageSource;
}
