使用MyEclice10+TomCat7.x进行的试验

LoginServlet类

package com.jacky.login;

import java.io.IOException;

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

public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;

@Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException {
String name = request.getParameter("username"); // 获取用户名
String pwd = request.getParameter("password"); // 获取密码

System.out.println("username:"
+ new String(name.getBytes("iso-8859-1"), "utf-8"));
System.out.println("password:" + pwd);
if ("abc".equals(name) && "123".equals(pwd)) {
response.getOutputStream().write("sucess".getBytes());
} else {
response.getOutputStream().write("login fail".getBytes());
}
}

@Override
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException {

System.out.println("post方式提交数据");
doGet(request, response);

}

}
