过滤器Filter解决中文乱码

为了servlet过多，编码设置代码重复性过大！
用过滤器解决：

package wzf.myfilter;

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 javax.servlet.annotation.WebFilter;

/**
 * Servlet Filter implementation class MyFilter
 */
@WebFilter("/MyFilter")
//Filter中文处理
public class MyFilter implements Filter {
    public MyFilter() {
    }
	public void destroy() {
	}
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
		  request.setCharacterEncoding("utf-8");
		  response.setContentType("text/html; charset=UTF-8");
		  chain.doFilter(request, response);
	}
	public void init(FilterConfig fConfig) throws ServletException {
	}

}

再在web.xml文件中配置一下：

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

就可以了！微笑！
