HttpServlet中解决中文输出浏览器乱码问题

出现乱码的原因：浏览器端编码格式与服务器端编码格式不一样

字节流输出中文乱码

public class TestClass extends HttpServlet {
	private static final long serialVersionUID = 1L;
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String outContent = "中文";
		//获取响应输出流
		ServletOutputStream sos = response.getOutputStream();
		//设置浏览器端的编码
		response.setHeader("Content-type", "text/html;charset=utf-8");
		//也可以简写response.setContentType("text/html;charset=utf-8");
		//设置服务端写出的格式
		sos.write(outContent.getBytes("utf-8"));
		
	}
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}

}

字符流输出中文乱码

private static final long serialVersionUID = 1L;
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String outContent = "中文666!@#";
		//设置服务端和客户端的编码形式
		response.setContentType("text/html;charset=utf-8");
		PrintWriter pw = response.getWriter();
		pw.write(outContent);
		
	}
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}

设置编码格式，尽量使用response.setContentType(“text/html;charset=utf-8”)方法，可以一步到位

常见支持中文的编码

GBK GB18030 GB2312，支持中文的编码，也支持其他一些字符

UTF-8万能码，支持所有字符
