1、webwork.properties文件中,添加:
webwork.i18n.encoding = GB2312
它主要是用來設置WebWork UI標籤庫的編碼,如果不設置它將通過
System.getProperty("file.encoding")來獲取默認字符編碼。
2、velocity.properties文件中,添加:
input.encoding=GB2312
output.encoding=GB2312
default.contentType=text/html; charset=GB2312
它是用來設置.vm頁面的編碼方式
3、寫一個Filter,將編碼設置爲GB2312。詳細請看附件中的SetCharacterEncodingFilter文件和Web.xml的配置。
它解決Action數據傳遞時的編碼。
建議:中文編碼推薦統一使用:GBK,它的字符集比GB2312更全。
