springMVC Controller的2种页面跳转方式的区别

http://localhost:8080/springmvcbase/login 登录时,controller中

@RequestMapping(value="/login",method=RequestMethod.POST)
public String login(String username,String password, Model model){
System.out.println("Controller here. annotation");
String url = "/pages/login";
if("admin".equals(username) && "8888".equals(password)){
//1.客户端跳转
//url = "redirect:/user/users";
//2.服务器端跳转
//url = "/pages/users";
}
return url;
} 

一 客户端跳转

url = "redirect:/user/users";
此种跳转为客户端跳转,浏览器的地址栏内容会变,显示
http://localhost:8080/springmvcbase/user.users
二服务器端跳转

url = "/pages/users";

此种跳转为服务器端跳转,浏览器的地址栏内容没有变化,依然是:
http://localhost:8080/springmvcbase/login
