用户在页面输入的中文数据，servlet如何获得正确的中文值

public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	// 告诉浏览器，返回的是html页面，而且是以utf-8编码的
	response.setContentType("text/html;charset=utf-8");
	
  	//request.setCharacterEncoding("UTF-8");
  	PrintWriter out = response.getWriter();
 	String name = request.getParameter("name");
 	
 	/*
 	 *其实servlet默认是以ISO-8859-1解码中文，这个肯定会出现乱码，因为浏览器就是以utf-8编码后传给服务器的；
 	 *name.getBytes("ISO-8859-1")这是以ISO-8859-1对错误的Unicode编码进行编码，重新获得utf-8编码，即字节数组；
 	 *new String(name.getBytes("ISO-8859-1"), "utf-8")这步是以utf-8重新解码得到正确的Unicode编码
 	 *正确的Unicode编码才能输出正确的中文字符
 	 */
 	String name2 = new String(name.getBytes("ISO-8859-1"), "utf-8");
 	
 	double salary = Double.parseDouble(request.getParameter("salary"));
 	int age = Integer.parseInt(request.getParameter("age"));
 	System.out.println("name:"+name2);
 	System.out.println("salary:"+salary);
 	System.out.println("age:"+age);
}

当然也可以这样子：

public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	response.setContentType("text/html;charset=utf-8");
	//这就是让servlet以utf-8解码参数值，那么就可以直接得到正确的中文值了
  	request.setCharacterEncoding("UTF-8");
  	PrintWriter out = response.getWriter();
 	String name = request.getParameter("name");
 	double salary = Double.parseDouble(request.getParameter("salary"));
 	int age = Integer.parseInt(request.getParameter("age"));
 	System.out.println("name:"+name);
 	System.out.println("salary:"+salary);
 	System.out.println("age:"+age);
}
