在做JSP系统时经常遇到的就是编码问题
而这个服务器可以是Tomcat、Weblogic，Tomcat服务器默认的编码为iso-8859-1，Weblogic默认的编码为UTF-8，所以程序运行时要注意编码设置
现在我们以一个jsp页面的代码，解释这些编码设置pageEncoding="UTF-8"说的是页面的编码，比如标题栏<title>还有其它内容等等
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">这代码说的是上下文编码，若我们设置charset="UTF-8"，那我们在点击这个页面跳到的那个Servlet或者jsp页面就要用"request.setCharacterEncoding("UTF-8");"和"String newsbody = new String(request.getParameter("editorValue").getBytes("iso-8859-1"),"UTF-8");"意思是设置接收到的字符串编码为UTF-8，响应的编码设置，可以用response.setContentType("text/html;charset=UTF-8");
<%@page import="java.net.URLDecoder"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
