reponse设置响应头

在web应用的src包下新建servlet，同时设置该servlet的url
servlet文件中的代码如下

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class responseAboutHttp
 */
public class responseAboutHttp extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public responseAboutHttp() {
        super();
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		// 1.通过setStatus设置响应行
		response.setStatus(200);
		// 2.通过setHeader设置响应头
		response.setHeader("name", "malihua");
		// 3.通过addHeader添加响应头
		response.addHeader("name", "yangbaoyu");
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}

在tomcat中运行此web应用抓包可得：
reponse设置响应头
由此设置了响应行以及设置和添加了响应头，设置响应行的状态吗为200，设置响应头的key为name，value为malihua另外还添加了key的value
