Spring Boot国际化
以 spring-boot-springmvc-demo1为例，在 src/main/resources 下创建一个 i18n 的目录，并在该目录中按照国际化资源文件命名格式分别创建以下三个文件，
- login.properties：无语言设置时生效
- login_en_US.properties ：英语时生效
- login_zh_CN.properties：中文时生效
login.properties
login.tip=登录系统
login.username=用户名
login.pwd=密码
login.submit=登录
login_en_US.properties
login.tip=Login System
login.username=username
login.pwd=password
login.submit=submit
login_zh_CN.properties
login.tip=登录系统
login.username=用户名
login.pwd=密码
login.submit=登录
login.html
