setcharacterencodingfilter.java

该源码是使用ajax技术实现的一个聊天室功能。如果想对程序进行修改

package filters;
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 SetCharacterEncodingFilter implements Filter {

	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 {
	}

	public void destroy() {
	}

}
