一、目的
針對不同地區，設置不同的語言信息。
SpringBoot國際化配置文件默認放在classpath:message.properties，如果自定義消息配置文件，需要application.properties或application.yml中設置spring.messages.basename的值。
二、步驟
在src/main/resources 下建i18n文件夾
在i18n文件夾中建立messages.properties 找不到語言配置時，使用此文件
hello=你好_默認
在i18n文件夾中建立messages_en_US.properties 英文語言配置
hello=hello_English
在i18n文件夾中建立messages_zh_CN.properties 中文語言配置
hello=你好_中文
