# 7.5.国际化

Spring Boot 支持本地化消息，以便您的应用程序可以满足不同语言偏好的用户。默认情况下，Spring Boot在类路径的根目录中查找`messages`资源包的存在。

当配置的资源包的默认属性文件可用时（默认情况下为`messages.properties`），自动配置适用。如果您的资源包仅包含特定于语言的属性文件，则需要添加默认值。如果没有找到与任何配置的基本名称匹配的属性文件，则不会有自动配置的 `MessageSource`。 可以使用`spring.messages`命名空间配置资源包的基本名称以及其他几个属性，如下例所示：

```
spring.messages.basename=messages,config.i18n.messages
spring.messages.fallback-to-system-locale=false
```

`spring.messages.basename`支持以逗号分隔的位置列表，可以是包限定符，也可以是从类路径根解析的资源。 更多支持选项，请参阅[`MessageSourceProperties`](https://github.com/spring-projects/spring-boot/tree/v2.7.3/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/context/MessageSourceProperties.java)。
