我正在开发一个具有以下要求的Web应用程序：

>允许用户登录
>在服务器端,用户通过第三方REST Web服务进行身份验证.
>如果身份验证成功,REST Web服务将返回唯一标记和密钥.
>对REST Web服务的任何后续请求必须包含第3点(上面)中收到的令牌.

我正在为web应用程序使用spring-mvc和spring security.
所以,我得到了一个解决方案,但是我刚接触弹簧并且不确定解决方案是否正确.

有人可以建议：

>解决方案是否正确实施？
>该解决方案是否会以任何方式影响性能？
>该解决方案是否会产生任何安全漏洞？

谢谢 ：)

解：

>我创建了一个MyUser对象,用于存储从REST服务收到的其他信息.

public class MyUser implements Serializable {

    private static final long serialVersionUID = 5047510412099091708L;
    private String RestToken;
    private String RestKey;

    public String getRestToken() {
        return RestToken;
    }
    public void setRestToken(String restToken) {
        RestToken = restToken;
    }
    public String getRestKey() {
        return RestKey;
    }
    public void setRestKey(String restKey) {
        RestKey = restKey;
    }
}

>然后我创建了一个扩展UsernamePasswordAuthenticationToken的MyAuthenticationToken对象.此对象将在CustomAuthenticationProvider中使用(下面的第3点).

public class MyAuthenticationToken extends UsernamePasswordAuthenticationToken {

        private static final long serialVersionUID = 7425814465946838862L;
        private MyUser myUser;

        public MyAuthenticationToken(Object principal,Object credentials,Collection

public class CustomAuthenticationProvider implements AuthenticationProvider {

        @Override
        public Authentication authenticate (Authentication authentication) {

            MyUser myUser = new MyUser();
            MyAuthenticationToken authenticationToken = null;
            String name = authentication.getName();
            String password = authentication.getCredentials().toString();

            //Just an example. This section will connect to a web service in order to authenticate the client
            if (name.equals("justh") && password.equals("123456")) {

                //Set the Token and Key Received from the REST WebService
                myUser.setRestKey("RestKey");
                myUser.setRestToken("RestToken");

                List

public ModelAndView adminPage(Authentication authentication) {

        MyUser user = null;
        //Get the additional data stored
        if(authentication instanceof MyAuthenticationToken){
            user = ((MyAuthenticationToken)authentication).getMyUser();
        }

        ModelAndView model = new ModelAndView();
        model.addObject("title","Spring Security Hello World");
        model.addObject("message","This is protected page - Admin Page!" + authentication.getName() + user.getRestKey() + user.getRestToken());
        model.setViewName("admin");
        return model;
    }
