Struts過濾器的使用,已解決中文問題

web.xml

????????<filter-name>Set?Character?Encoding</filter-name>

????????<filter-class>mypack.Charset</filter-class>

????????<init-param>

????????????<param-name>encoding</param-name>

????????????<param-value>UTF-8</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>

????<servlet-name>action</servlet-name>

??</filter-mapping>

過濾的類

package mypack;

import?java.io.*;

import?javax.servlet.*;

public?class?Charset?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?{

????????if?(ignore?||?(request.getCharacterEncoding()?==?null))?{

????????????String?encoding?=?selectEncoding(request);

????????????if?(encoding?!=?null)

????????????????request.setCharacterEncoding(encoding);

????????}

????????chain.doFilter(request,?response);

????}

????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);

????}

}

這2個加進工程里，就可以直接運行了。不用在設置什么。
至于數(shù)據(jù)庫最好設置為UTF-8.
從此以后遠離中文出現(xiàn)亂碼的煩惱。哈哈哈
