springsecurity4+springboot 实现remember-me 发现springsecurity 的BUG

前言：现在开发中，记住我这个功能是普遍的，用户不可能每次登录都要输入用户名密码。昨天准备用spring security的记住我功能，各种坑啊，吐血。

先看下具体实现吧。

spring security 对remember-me 进行了封装，大概流程是首先用户的表单必须有这个记住我的字段。

1.安全配置

以下是代码（红色字体注释是关键）

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(4);
    }
   //spring security 内部都写死了，这里要把 这个DAO 注入
    @Bean
    public JdbcTokenRepositoryImpl tokenRepository(){        
        JdbcTokenRepositoryImpl j=new JdbcTokenRepositoryImpl();
        j.setDataSource(dataSource);
        return j;
    }
    /**
     * 用户或者管理员登录日志
     */
    @Bean
    public LoginSuccessHandler loginSuccessHandler(){
        return new LoginSuccessHandler();
    }
    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider);
        auth.userDetailsService(userDetailsService);
    }



}

2 前端页面，这个简单

   <div class="checkbox">
          <label><input type="checkbox" id="rememberme" name="remember-me"/> Remember Me</label>  
     </div>

3 、数据库表，因为 spring security 内部把表写死了，可以看源码

 * @author Luke Taylor
 * @since 2.0
 */
public class JdbcTokenRepositoryImpl extends JdbcDaoSupport implements
        PersistentTokenRepository {
    // ~ Static fields/initializers
    // =====================================================================================

    /** Default SQL for creating the database table to store the tokens */
    public static final String CREATE_TABLE_SQL = "create table persistent_logins (username varchar(64) not null, series varchar(64) primary key, "
            + "token varchar(64) not null, last_used timestamp not null)";
    /** The default SQL used by the <tt>getTokenBySeries</tt> query */
    public static final String DEF_TOKEN_BY_SERIES_SQL = "select username,series,token,last_used from persistent_logins where series = ?";
    /** The default SQL used by <tt>createNewToken</tt> */
    public static final String DEF_INSERT_TOKEN_SQL = "insert into persistent_logins (username, series, token, last_used) values(?,?,?,?)";
    /** The default SQL used by <tt>updateToken</tt> */
    public static final String DEF_UPDATE_TOKEN_SQL = "update persistent_logins set token = ?, last_used = ? where series = ?";
    /** The default SQL used by <tt>removeUserTokens</tt> */
    public static final String DEF_REMOVE_USER_TOKENS_SQL = "delete from persistent_logins where username = ?";

这个表名必须是persistent_logins

CREATE TABLE `persistent_logins` (
  `username` varchar(64) NOT NULL,
  `series` varchar(64) NOT NULL,
  `token` varchar(64) NOT NULL,
  `last_used` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`series`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

==========================================================================================其实到这里基本是没问题的，如果用 springsecurity 默认 授权验证

springsecurity 默认都是用户名+密码登录， 但是现在系统很多都是用户手机号+手机验证码登录，我这里就是这么实现的，手机验证码必须从第三方短信获取， 所以必须自定义授权验证
 


先看下我的自定义验证类

package com.ycmedia.security;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import com.ycmedia.service.UserService;
import com.ycmedia.utils.HttpRequest;

/**

@Component
public class YcAnthencationProder implements AuthenticationProvider {
    @Autowired
    private UserService userService;
    BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
    @Autowired
    private Environment env;

    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {
//        CustomWebAuthenticationDetails details = (CustomWebAuthenticationDetails) authentication
//                .getDetails(); // 如上面的介绍，这里通过authentication.getDetails()获取详细信息
        // 用户名
        String username = authentication.getName();
        // 验证码
        String password = (String) authentication.getCredentials();
        Customer user = userService.getUserByname(username);
        List<SimpleGrantedAuthority> auths = new ArrayList<>();
        
        System.out.println("用户"+authentication.getName()+"正在获取权限");
        //游客=》提示用户去注册
        if(user==null){
            //授权
            auths.add(new SimpleGrantedAuthority(Role.ROLE_TOURIST.toString()));
            auths.add(new SimpleGrantedAuthority(username));
            auths.add(new SimpleGrantedAuthority(password));
            return new UsernamePasswordAuthenticationToken(new Customer(), password,
                    auths);
        }else{
            //存在此用户，调用登录接口
            String data = HttpRequest.sendGet(env.getProperty("login.url"),
                    "mobile=" + username+"&smsCode="+password);
            JSONObject json = JSONObject.parseObject(data);
            if(json.getBoolean("success")==true)){
                //验证码和手机号码正确,返回用户权限
                switch(user.getRole()){
                  case 0:auths.add(new SimpleGrantedAuthority(Role.ROLE_USER.toString()));
                  case 1:auths.add(new SimpleGrantedAuthority(Role.ROLE_CHANNEL.toString()));
                  case 2:auths.add(new SimpleGrantedAuthority(Role.ROLE_ADMIN.toString()));
                }
            }else{
                //验证消息放到权限里面， 页面提示
                auths.add(new SimpleGrantedAuthority(Role.ROLE_WRONGCODE.toString()));
                auths.add(new SimpleGrantedAuthority(username));
                auths.add(new SimpleGrantedAuthority(password));
            }
        }
        
        return new RememberMeAuthenticationToken(username, user, auths);
//        return new UsernamePasswordAuthenticationToken(user, password,
//                auths);

    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

实现 这个接口就行AuthenticationProvider， 
但是，结果
        return new UsernamePasswordAuthenticationToken(user, password,
                auths);
返回一个 UsernamePasswordAuthenticationToken  对象， 这个对象，是继承了 AbstractAuthenticationToken

而AbstractAuthenticationToken 又是 Authentication 的子类，

这个UsernamePasswordAuthenticationToken  看下他的源码

    }

    @Override
    public void eraseCredentials() {
        super.eraseCredentials();
        credentials = null;
    }
}

发现上springsecurity 的问题主要是

   private final Object principal; 

 principal  是个 object 类型的， 可以存的信息有两种，第一这个用户对象， 第二， 用户名。 spring security 默认存的是  用户对象。
    @RequestMapping(value = "/order-list")
    public ModelAndView addSystemUser(Model model) {
        
        Customer user= (Customer) AuthUtils.getAuthenticationObject().getPrincipal();
        model.addAttribute("role", user.getRole());
        model.addAttribute("username", user.getMobile());
        return new ModelAndView("order-list");
    }
 这是我的一个 controller 方法，   Customer user= (Customer) AuthUtils.getAuthenticationObject().getPrincipal(); 返回客户所有， 包括角色 ，权限，然后扔给前端，，这样看起来没错 啊。

最最坑的 的地方来了

这里是重点。
先看下这个类   PersistentTokenBasedRememberMeServices
 看名字， 持久化 token 记住我 service；
再看他的类前部分

//继承了 AbstractRememberMeServices 
public class PersistentTokenBasedRememberMeServices extends AbstractRememberMeServices {
    // 还记得之前安全配置注入的DAo吗， 在这里
    private PersistentTokenRepository tokenRepository = new InMemoryTokenRepositoryImpl();
    private SecureRandom random;

    public static final int DEFAULT_SERIES_LENGTH = 16;
    public static final int DEFAULT_TOKEN_LENGTH = 16;

    private int seriesLength = DEFAULT_SERIES_LENGTH;
    private int tokenLength = DEFAULT_TOKEN_LENGTH;

    public PersistentTokenBasedRememberMeServices(String key,
            UserDetailsService userDetailsService,
            PersistentTokenRepository tokenRepository) {
        super(key, userDetailsService);
        random = new SecureRandom();
        this.tokenRepository = tokenRepository;
    }


=====================================这里看起来正常
再看看核心方法

// 当一个用户登录成功， 并使用记住我会调用这个份方法    

protected void onLoginSuccess(HttpServletRequest request,
            HttpServletResponse response, Authentication successfulAuthentication) {
        //这里就是spring security 有BUG的地方， 因为  Authentication  successfulAuthentication 这个对象默认存的是 用户对象，  getName() 返回的就是一个这个对象的地址值
        String username = successfulAuthentication.getName();

        logger.debug("Creating new persistent login for user " + username);
        //这里是存储这个token到数据库
        PersistentRememberMeToken persistentToken = new PersistentRememberMeToken(
                username, generateSeriesData(), generateTokenData(), new Date());
        try {
            tokenRepository.createNewToken(persistentToken);
            addCookie(persistentToken, request, response);
        }
        catch (Exception e) {
            logger.error("Failed to save persistent token ", e);
        }
    }

这是数据库的数据， username 是一个对象

，当用户关闭浏览器的后，

再次打开浏览器进入网址，立即报错

2016-11-23 12:18:44.056 [http-nio-7070-exec-1] DEBUG c.y.dao.UserDao.findUserByMobile - ==> Parameters: com.ycmedia.entity.Customer@42feadb2(String)

java.lang.NullPointerException: null

第二次登录的时候根据这个名字去查，因为不是用户名，而是用户名地址值，肯定报错！

好吧，用 UsernamePasswordAuthenticationToken 这个子类做记住我，感觉不靠谱，

看下他还有别的兄弟没

发现，大概只有一个兄弟，感觉有点靠谱，点进去

这是他的构造

    public RememberMeAuthenticationToken(String key, Object principal,
            Collection<? extends GrantedAuthority> authorities) {
        super(authorities);

        if ((key == null) || ("".equals(key)) || (principal == null)
                || "".equals(principal)) {
            throw new IllegalArgumentException(
                    "Cannot pass null or empty values to constructor");
        }

        this.keyHash = key.hashCode();
        this.principal = principal;
        setAuthenticated(true);
    }

三个参数吧， key , Object principal 用户信息 authorities 用户权限。

但是，即使这里我把 key 设置成用户名，principal 保存用户的对象，

// return new RememberMeAuthenticationToken(username, user, auths);

但是，

这里依然还是调用获取 principal 而不是， key

看下去头都大了

最后没办法，你改变不了他，只能适应他

return new UsernamePasswordAuthenticationToken(username, password,
auths);
把用户名存进去。

当别的接口要获取要多做一步查询根据用户名去查权限

    @RequestMapping(value = "/customer-list")
    public ModelAndView addSystemUser(Model model) {
        String userName=  (String) AuthUtils.getAuthenticationObject().getPrincipal();
        Customer user=userService.getUserByname(userName);
        model.addAttribute("role", user.getRole());
        model.addAttribute("username", user.getMobile());
        return new ModelAndView("customer-list");
    }

而不是比较方便的

    @RequestMapping(value = "/customer-list")
    public ModelAndView addSystemUser(Model model) {
        Customer user= (Customer) AuthUtils.getAuthenticationObject().getPrincipal();
        model.addAttribute("role", user.getRole());
        model.addAttribute("username", user.getMobile());
        return new ModelAndView("customer-list");
    }

综上我感觉 spring security 的 Authentication 对象， Object getPrincipal(); 获取用户的信息，要么就是一个对象，要么新加一个字段存用户名，这样搞成object类型。
