HttpServletResponse解决中文乱码-----字符流输出response.getWriter().write()方式

### 响应的数据中有中文，那么有可能出现中文乱码

* 以字符流输出

 response.getWriter()

 

 

Response01:

package com.yuming.servlet;

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 Response01
 */
public class Response01 extends HttpServlet {

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		//test01(response);
		
		//响应的数据中有中文，那么有可能出现中文乱码
			//1.以字符流输出  response.getWriter()方式
		
		//1.1 (设置输出的编码格式)指定输出到客户端的时候，这些文字使用UTF-8编码
		response.setCharacterEncoding("UTF-8");
		
		//2.直接规定浏览器看这份数据的时候，使用什么编码来看。
		response.setHeader("Content-Type", "text/html; charset=UTF-8");
		
		response.getWriter().write("北京");
		
		
	}


	private void test01(HttpServletResponse response) throws IOException {
		//1.以字符流的方式响应数据
		//response.getWriter().write("
hello response1111111
");
		
		//2.以字节流的方式响应数据
		response.getOutputStream().write("
hello response222222222
".getBytes());
		
		//3.设置当前请求的处理状态码
		//response.setStatus(0, "");
		
		//4.设置一个头
		//response.setHeader(name, value);
		//5.设置响应的内容类型,以及编码
		//response.setContentType(type);
	}

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