jboss 4.03,tomcat5.5应用struts开发,在action中得到form的中文属性值是乱码

Question

1. 首先定义一个自己的ActionServlet, 在其中设置Request的编码格式
public class SmpeActionServlet extends ActionServlet {
    protected void process(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException {
        request.setCharacterEncoding(AppConsts.ENC_TYPE_GBK);
        super.process(request, response);
    }    
}2. 在Web.xml中将.do定向到此Servlet进行处理
        <servlet-class>com.ls.websrv.framework.SmpeActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <init-param>
            <param-name>debug</param-name>
            <param-value>2</param-value>
        </init-param>
        <init-param>
            <param-name>detail</param-name>
            <param-value>2</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>action</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

Answer 1

通过parameter传递到action中是中文，但是从form中得到就是乱码

Answer 2

写一个filter过滤器package com.cn.throughout.util;import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.UnavailableException;public class SetCharacterEncodingFilter implements Filter { 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 {
response.setContentType("text/html;charset=UTF-8");
//    Conditionally select and set the character encoding to be used
if (ignore || (request.getCharacterEncoding() == null)) {
String encoding = selectEncoding(request);
if (encoding != null)
request.setCharacterEncoding(encoding);
} chain.doFilter(request, response);
} private String selectEncoding(ServletRequest request) {
return (this.encoding);
}
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;
}
}
