上传文件乱码问题

今天在用struts1框架实验文件上传的功能时，出现了乱码的现象，后期经过查阅资料找到了一个解决方案，试了很多次，个人感觉这个方案确实很好用

前提是用struts1框架进行开发

编写一个自己的ActionServlet类，例如ChinaActionServlet类，继承ActionServlet类

代码如下：

/** *  */package com.sotaof.struts.action;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.ActionServlet;/**    * @Title: ChinaActionServlet.java * @Package com.sotaof.struts.action * @Description: TODO * @author A18ccms A18ccms_gmail_com    * @date 2013-1-19 下午03:19:41 * @version V1.0    */public class ChinaActionServlet extends ActionServlet {@Overrideprotected void process(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException {request.setCharacterEncoding("utf-8");response.setCharacterEncoding("utf-8");super.process(request, response);}}

然后在web.xml文件中配置如下：

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <servlet>    <servlet-name>action</servlet-name>    <servlet-class>com.sotaof.struts.action.ChinaActionServlet</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>3</param-value>    </init-param>    <init-param>      <param-name>detail</param-name>      <param-value>3</param-value>    </init-param>    <load-on-startup>0</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>action</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

修改之前，原来的结构如下（第八行有区别）：

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <servlet>    <servlet-name>action</servlet-name>    <servlet-class>org.apache.struts.action.ActionServlet</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>3</param-value>    </init-param>    <init-param>      <param-name>detail</param-name>      <param-value>3</param-value>    </init-param>    <load-on-startup>0</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>action</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

经过这两步的修改，就可以了！！！
