Struts1.2里提交中文表单到ActionForm后的��q��问题

sk — Sat, 22 Nov 2008 14:35:00 GMT

�׃��Struts框架直接把表单数据发送给了ActionForm�Q�所以这里面没有对HttpRequestServlet�q�行SetCharacterEncoding,所以默认是按照ISO-8859-1(参见Tomcat 源代码中的org.apache.catalina.connector.HttpRequestBase中的protected void parseParameters()�Ҏ��)�Q?/p>

解决的方法，��是在表单提交到ActionForm之前对request�q�行�~�码�?br /> �W�一�U�方法，��是写一个过滤器�Q�对所有请求进行过�?br />
�q��o器代�?

package com.first.struts.filters;

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;

public class SetCharacterEncodingFilter implements Filter {

private String encoding;
private FilterConfig filterConfig = null;

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

}

public void doFilter(ServletRequest request, ServletResponse response,
   FilterChain chain) throws IOException, ServletException {
  request.setCharacterEncoding(this.encoding);
  chain.doFilter(request, response);
}

public void init(FilterConfig filterConfig) throws ServletException {
  this.encoding = filterConfig.getInitParameter("encoding");
}

}

配置文�gweb.xml

  <filter>
  <filter-name>Set Character Encodingfilter-name>
  <filter-class>com.first.struts.filters.SetCharacterEncodingFilterfilter-class>
  <init-param>
   <param-name>encodingparam-name>
   <param-value>GBKparam-value>
  init-param>
filter>

<filter-mapping>
  <filter-name>Set Character Encodingfilter-name>
  <url-pattern>/*url-pattern>
filter-mapping>
  filter-mapping>

�W�二�U�方法是替换默认的控制器org.apache.struts.action.ActionServlet
子类代码:

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionServlet;

public class SetEncodingActionServlet extends ActionServlet {
protected void process(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
  // TODO Auto-generated method stub
  String encoding = getInitParameter("encoding");
  request.setCharacterEncoding(encoding);
  super.process(request, response);
}
}

配置文�gweb.xml

<servlet>
    <servlet-name>testActionservlet-name>
    <servlet-class>jp.co.ricoh.gtis.others.profile.controllers.SetEncodingActionServletservlet-class>
    <init-param>
      <param-name>configparam-name>
      <param-value>/WEB-INF/struts-config.xmlparam-value>
    init-param>
    <init-param>
      <param-name>encodingparam-name>
      <param-value>Shift_JISparam-value>
    init-param>
    <load-on-startup>2load-on-startup>
  servlet>

  <servlet-mapping>
    <servlet-name>testActionservlet-name>
    <url-pattern>*.testdourl-pattern>
  servlet-mapping>

此例�Q�凡是通过*.testdo来请求的数据�Q�都会经�q�参数encoding讑֮�的值来�~�码�?br />
