Spring国际化配置。

1，配置ResourceBundleMessageSource。

    @Bean
    public ResourceBundleMessageSource messageSource(){
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setBasenames("i18n/messages");
        messageSource.setCacheSeconds(10);
        return messageSource;
}```
```java
    <bean id="messageSource"  
     class="org.springframework.context.support.ResourceBundleMessageSource">  
        <!-- 其中basename用来指定properties文件的通用名 如实例中的messages_en.properties,messages_ja.properties通用名都是messages -->  
        <property name="basename" value="i18n/messages" />  
        <property name="useCodeAsDefaultMessage" value="true" />  
  
    </bean>```

####2，配置文件路径以及创建。

####3，前端调用

<div><sp:message code="welcome"></sp:message></div>

####4，浏览器设置
