使用Get方式提交数据到Tomcat服务器的方法

//使用Get方式向服务器提交数据 
public void doGet(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException { 
//获取从浏览器中发送过来的用户名 
String username = request.getParameter("username"); 
//获取从客户端发送过来的密码 
String password = request.getParameter("password"); 
//使用iso8859-1编码将username转换成字节数组 
//再使用utf-8把字节数组转换成字符串 
username = new String(username.getBytes("iso8859-1"), "utf-8"); 
//在控制台中打印用户名和密码 
System.out.println("username=" + username); 
System.out.println("password=" + password); 
//获得一个输出流 
OutputStream os = response.getOutputStream(); 
//如果用户名和密码都输入正确 
if("小志".equals(username) && "123".equals(password)) { 
//将字符发送至浏览器中 
os.write("登录成功".getBytes("utf-8")); 
} 
else { 
//将字符串发送到浏览器中 
os.write("登录失败".getBytes("utf-8")); 
} 
} 
//使用Post方式向服务器提交数据 
public void doPost(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException { 
} 
}
