Struts过滤器的使用,已解决中文问题

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>

过滤的类

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);

}

这2个加进工程里，就可以直接运行了。不用在设置什么。
至于数据库最好设置为UTF-8.
从此以后远离中文出现乱码的烦恼。哈哈哈
