servlet重定向与编码设置方法实例介绍，servlet使用实例简单代码。

package cn.csdn.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import cn.csdn.service.UserService;
import cn.csdn.service.UserServiceImpl;

@SuppressWarnings(“serial”)
public class SecondServlet extends HttpServlet{

/*声明一个service对象*/
private UserService uService = new UserServiceImpl();

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stu

System.out.println(“httpServlet doGet执行”);

//重定向
/* resp.setStatus(302);
resp.setHeader(“location”,”./index.html”);*/
resp.sendRedirect(“./index.html”);
}

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
/*设置请求的编码方式*/
request.setCharacterEncoding(“UTF-8″);
/*获取传递的参数*/
String uname = request.getParameter(“uname”);
String upass = request.getParameter(“upass”);
/*验证用户名和密码是否存在*/
boolean flag = uService.loginCheck(uname, upass);
if(flag){
//重定向
response.sendRedirect(“./success.html”);
}else{
response.sendRedirect(“./error.html”);

}

}
