Question

Struts2在action配置文件中传参在JSP页面显示乱码的问题！！！！

<action name="saveKc" class="com.cvicse.hs.cyxt.kcgl.action.KcglAction" method="saveKc">
<result type="redirect">/kcgl/editKcInit.action?kcdm=${kcdm}&message=${message}</result>
在action1中定义String message="保存成功！";保存功能执行后，从这个action1传到另一个action2，然后在页面显示提示信息。有set和get方法。JSP页面用的都是GBK的编码方式。
我把配置文件中加入<constant name="struts.i18n.encoding" value="GBK" /> 解决乱码。但是不行！！！把tomcat下的config中的service文件中8080后加入URIencoding="GBK";也还是不行。在action2中message =new String(message.getBytes(),"GBK");还是乱码。郁闷死了..!谁能给我说下怎么解决这个乱码问题啊！！急~~~~~~~~~~~
唉，你们说的这些方法 我都用了 都不行 我真不知道哪里出问题了。

Answer 1

首先编写一个Filter
public class SetCharacterEncodingFilter implements Filter {
private Logger log = Logger.getLogger(this.getClass());
protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;

public void destroy() {
this.encoding = null;
this.filterConfig = null;
}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
try{
if (ignore || (request.getCharacterEncoding() == null)) {
String encoding = selectEncoding(request);
if (encoding != null)
request.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}catch(Exception e){
log.error("",e);
}
}

public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");
String value = filterConfig.getInitParameter("ignore");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase("true"))
this.ignore = true;
else if (value.equalsIgnoreCase("yes"))
this.ignore = true;
else
this.ignore = false;
}

protected String selectEncoding(ServletRequest request) {
return (this.encoding);
}

}

然后修改web.xml，添加下面代码
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>com.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
<init-param>
<param-name>ignore</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

这样中文就不会是乱码了

Answer 2

只说一句“所有配置及JSP文件统一编码”

Answer 3

设置request对象的编码格式为GBK。

Answer 4

配置一个过滤器.
把页面,程序,配置文件,数据库中的编码统一了.

Answer 5

<?xml version="1.0" encoding="UTF-8"?>

<result type= "chain">action2</result>
或<result type= "redirectAction">action2</result>
