struts中文设置

先写个过滤器

package cn.javabiz;

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 MyFilter implements Filter
{

	public void destroy() 
	{
		
	}

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException 
			{
		request.setCharacterEncoding("utf-8");
		chain.doFilter(request, response);
	}

	public void init(FilterConfig filterConfig) throws ServletException 
	{
		
	}

}

再配置web.xml文件，注意<filter>一定要放在<servlet>的前面

<filter>
		<filter-name>myfilter</filter-name>	
		<filter-class>cn.javabiz.MyFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>myfilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
