response控制浏览器实现重定向

package ResponseDemo;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class RedirectTest extends HttpServlet
{
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException
	{
		//设置请求重定向，重定向至：/ResponseTest/index.jsp
		response.setStatus(302);
		response.setHeader("location","/ResponseTest/index.jsp");
		//以下一行代码可以代替以上两行
		//response.sendRedirect("/ResponseTest/index.jsp");
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException
	{
		doGet(request, response);
	}

}

其在web.xml中的配置为：

<servlet>
    <servlet-name>RedirectTest</servlet-name>
    <servlet-class>ResponseDemo.RedirectTest</servlet-class>
  </servlet>
<servlet-mapping>
    <servlet-name>RedirectTest</servlet-name>
    <url-pattern>/servlet/RedirectTest</url-pattern>
  </servlet-mapping>
