struts1 actionfrom提交的时候,出现乱码
昨天,做个了博客系统.数据库是GB2312.
JSP页面是UTF-8.
java文件是GBK
在数据存入的时候出现乱码.纠结了一上午.最后发现struts的actionfrom默认的编码居然是ISO-8859-1的.
最重写了ActionServlet的process方法.在web.xml里面加上了一个编码.然后搞定了.哎·~~只是个笔记先.请大家不要评论了.如果能帮助你,那你就拿去.
下面是代码：有可能以后还会遇到类似的问题.
新建一个类:
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 {/* (non-Javadoc) * @see org.apache.struts.action.ActionServlet#process(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) */@Overrideprotected void process(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException {String encoding = getInitParameter("encoding");request.setCharacterEncoding(encoding);super.process(request, response);}}
web.xml的配置：
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><display-name>LibraryManage</display-name><servlet> <servlet-name>action</servlet-name> <servlet-class>com.yangjie.core.SetEncodingActionServlet</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> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</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> <!-- 设置默认文件名称 --><welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list> </web-app>
