struts2中如何用过滤器处理中文乱码

CharaterencodeFilter
com.CharaterEncodeFilter


CharaterencodeFilter
/*


放在web.xml里
相应的类也给你
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;
import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;
public class CharaterEncodeFilter implements Filter {
private FilterConfig config = null;

public void destroy() {
this.config = config;
}

public void doFilter(ServletRequest request， ServletResponse response，FilterChain chain) throws IOException， ServletException {

request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
chain.doFilter(request， response);
}

public void init(FilterConfig arg0) throws ServletException {
config = null;
}

}

创建过滤器，web.xml里配置过滤所有请求，过滤器了不是request和response的字符设为utf-8，转入下一个资源。
抱歉没有相关代码，别人的电脑。乱码处理不难，过滤器会就好了
