要求:创建一个首页,默然显示英文信息,但可以让用户选择使用英文,繁体中文或简体中文.

1.编写hello_en_US.txt,内容如下:

cc.openhome.welcome=welcome
cc.openhome.font=English
cc.openhome.name=This is your front page

2.编写hello_zh_CN.txt,内容如下:

cc.openhome.welcome=欢迎
cc.openhome.font=简中
cc.openhome.name=这是你的预设首页

3.编写hello_zh_TW.txt,内容如下:

cc.openhome.welcome=歡迎
cc.openhome.font=繁中
cc.openhome.name=這是你的預設首頁

4.文件编码需要注意:

在idea18 中英文和简体中文 .txt文本编辑采用的UTF-8格式,编码格式使用的是:jdk自带的native2ascii 生成 .propertities

$ native2ascii -encoding utf-8 hello_en_US.txt hello_en_US.properties

中文繁体编码采用的big5 编码方式,需要把编辑器设置为Big5编码格式,类似:编码为Big5

$ native2ascii -encoding Big5 hello_zh_TW.txt hello_zh_TW.properties

5.处理请求jsp
