WebWork+Velocity中文问题解决

 

1、webwork.properties文件中，添加：
webwork.i18n.encoding = GB2312
它主要是用来设置WebWork UI标签库的编码，如果不设置它将通过
System.getProperty("file.encoding")来获取默认字符编码。

2、velocity.properties文件中，添加：
input.encoding=GB2312
output.encoding=GB2312
default.contentType=text/html; charset=GB2312
它是用来设置.vm页面的编码方式

3、写一个Filter，将编码设置为GB2312。详细请看附件中的SetCharacterEncodingFilter文件和Web.xml的配置。
它解决Action数据传递时的编码。

建议：中文编码推荐统一使用：GBK，它的字符集比GB2312更全。

web.xml
