Spring security(四)-spring boot

发布时间:2020-07-18 23:00:10 来源:网络 阅读:392 作者:艾弗森哇 栏目:开发技术

现在主流的登录方式主要有 3 种:账号密码登录、短信验证码登录和第三方授权登录,前面一节Spring security(三)---认证过程已分析了spring security账号密码方式登陆,现在我们来分析一下spring security短信方式认证登陆。

  Spring security 短信方式、IP验证等类似模式登录方式验证,可以根据账号密码方式登录步骤仿写出来,其主要以以下步骤进行展开:

  1. 自定义Filter:

  2. 自定义Authentication

  3. 自定义AuthenticationProvider

  4. 自定义UserDetailsService

  5. SecurityConfig配置

1. 自定义filter:

  自定义filter可以根据UsernamePasswordAuthenticationFilter过滤器进行仿写,其实质即实现AbstractAuthenticationProcessingFilter抽象类,主要流程分为:

  1. 构建构造器,并在构造器中进行配置请求路径以及请求方式的过滤

  2. 自定义attemptAuthentication()认证步骤

  3. 在2步骤中认证过程中需要AuthenticationProvider进行最终的认证,在认证filter都需要将AuthenticationProvider设置进filter中,而管理AuthenticationProvider的是AuthenticationManager,因此我们创建过滤器filter的时候需要设置AuthenticationManager,这步具体详情在5.1 SecurityConfig配置步骤

在第2步中attemptAuthentication()认证方法主要进行以下步骤:
   1).post请求认证;
   2).request请求获取手机号码和验证码;
   3).用自定义的Authentication对象封装手机号码和验证码;
   4).使用AuthenticationManager.authenticate()方法进行验证。

自定义filter实现代码:

public class SmsAuthenticationfilter extends AbstractAuthenticationProcessingFilter {    private boolean postOnly = true;    public SmsAuthenticationfilter() {      super(new AntPathRequestMatcher(SecurityConstants.APP_MOBILE_LOGIN_URL, "POST"));
   }


    [@Override](https://my.oschina.net/u/1162528)
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {        if (postOnly && !request.getMethod().equals("POST")) {              throw new AuthenticationServiceException(                   "Authentication method not supported: " + request.getMethod());
      }
        Assert.hasText(SecurityConstants.MOBILE_NUMBER_PARAMETER, "mobile parameter must not be empty or null");
     
         String mobile = request.getParameter(SecurityConstants.MOBILE_NUMBER_PARAMETER);
        String smsCode = request.ge+tParameter(SecurityConstants.MOBILE_VERIFY_CODE_PARAMETER);        if (mobile == null) {
            mobile="";
        }        if(smsCode == null){
            smsCode="";
        }
        mobile = mobile.trim();
        smsCode = smsCode.trim();
        SmsAuthenticationToken authRequest = new SmsAuthenticationToken(mobile,smsCode);        // Allow subclasses to set the "details" property
        setDetails(request, authRequest);    
        return this.getAuthenticationManager().authenticate(authRequest);
    }protected void setDetails(HttpServletRequest request,
                              SmsAuthenticationToken authRequest) {
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
    }    public void setPostOnly(boolean postOnly) {        this.postOnly = postOnly;
    }

}

2. Authentication:

  在filter以及后面的认证都需要使用到自定义的Authentication对象,自定义Authentication对象可以根据UsernamePasswordAuthenticationToken进行仿写,实现AbstractAuthenticationToken抽象类。https://www.jianshu.com/p/5e19f3a9f6dd

自定义SmsAuthenticationToken:

public class SmsAuthenticationToken extends AbstractAuthenticationToken {    private final Object principal;    private Object credentials;    public SmsAuthenticationToken(Object principal,Object credentials ) {        super(null);        this.principal = principal;        this.credentials=credentials;
        setAuthenticated(false);
    }    public SmsAuthenticationToken(Object principal, Object credentials,Collection<? extends GrantedAuthority> authorities) {        super(null);        this.principal = principal;        this.credentials=credentials;
        setAuthenticated(true);
    }

    [@Override](https://my.oschina.net/u/1162528)
    public Object getCredentials() {        return this.credentials=credentials;
    }

    [@Override](https://my.oschina.net/u/1162528)
    public Object getPrincipal() {        return this.principal;
    }    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {        if (isAuthenticated) {            throw new IllegalArgumentException(                    "Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        }        super.setAuthenticated(false);
    }

    [@Override](https://my.oschina.net/u/1162528)
    public void eraseCredentials() {        super.eraseCredentials();

    }
}

3.AuthenticationProvider

  AuthenticationProvider最终认证策略入口,短信方式验证需自定义AuthenticationProvider。可以根据AbstractUserDetailsAuthenticationProvider进行仿写,实现AuthenticationProvider以及MessageSourceAware接口。认证逻辑可以定义实现。焦作国医堂胃肠医院正规吗:http://jz.lieju.com/zhuankeyiyuan/37174867.htm

自定义AuthenticationProvider:

public class SmsAuthenticationProvide implements AuthenticationProvider, MessageSourceAware {  private UserDetailsService userDetailsService;  private MessageSourceAccessor messages = SpringSecurityMessageSource.getAccessor();

    [@Override](https://my.oschina.net/u/1162528)
    public void setMessageSource(MessageSource messageSource) {        this.messages = new MessageSourceAccessor(messageSource);
    }    @Override
    public Authentication authenticate(Authentication authentication) {
        Assert.isInstanceOf(SmsAuthenticationToken.class, authentication,
                messages.getMessage(                        "AbstractUserDetailsAuthenticationProvider.onlySupports",                        "Only UsernamePasswordAuthenticationToken is supported"));
        SmsAuthenticationToken authenticationToken = (SmsAuthenticationToken) authentication;        //将验证信息保存在SecurityContext以供UserDetailsService进行验证
        SecurityContext context = SecurityContextHolder.getContext();
        context.setAuthentication(authenticationToken);
        String mobile = (String) authenticationToken.getPrincipal();        if (mobile == null) {            throw new InternalAuthenticationServiceException("can't obtain user info ");
        }
        mobile = mobile.trim();        //进行验证以及获取用户信息
        UserDetails user = userDetailsService.loadUserByUsername(mobile);        if (user == null) {            throw new InternalAuthenticationServiceException("can't obtain user info ");
        }
        SmsAuthenticationToken smsAuthenticationToken = new SmsAuthenticationToken(user, user.getAuthorities());        return smsAuthenticationToken;
    }    @Override
    public boolean supports(Class<?> authentication) {        return (SmsAuthenticationToken.class.isAssignableFrom(authentication));
    }    public void setUserDetailsService(UserDetailsService userDetailsService) {        this.userDetailsService = userDetailsService;
    }    public UserDetailsService getUserDetailsService() {        return userDetailsService;
    }
}

4. UserDetailsService

  在AuthenticationProvider最终认证策略入口,认证方式实现逻辑是在UserDetailsService。可以根据自己项目自定义认证逻辑。

自定义UserDetailsService:

public class SmsUserDetailsService implements UserDetailsService {    @Autowired
    private RedisUtil redisUtil;    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {        //从SecurityContext获取认证所需的信息(手机号码、验证码)
        SecurityContext context = SecurityContextHolder.getContext();
        SmsAuthenticationToken authentication = (SmsAuthenticationToken) context.getAuthentication();        if(!additionalAuthenticationChecks(username,authentication)){            return null;
        }        //获取用户手机号码对应用户的信息,包括权限等
        return new User("admin", "123456", Arrays.asList(new SimpleGrantedAuthority("admin")));
    }    public boolean additionalAuthenticationChecks(String mobile, SmsAuthenticationToken smsAuthenticationToken) {        //获取redis中手机键值对应的value验证码
        String smsCode = redisUtil.get(mobile).toString();        //获取用户提交的验证码
        String credentials = (String) smsAuthenticationToken.getCredentials();        if(StringUtils.isEmpty(credentials)){            return false;
        }        if (credentials.equalsIgnoreCase(smsCode)) {            return true;
        }        return false;
    }
}

5.SecurityConfig

5.1 自定义Sms短信验证组件配置SecurityConfig

  将自定义组件配置SecurityConfig中,可以根据AbstractAuthenticationFilterConfigurer(子类FormLoginConfigurer)进行仿写SmsAuthenticationSecurityConfig,主要进行以下配置:

  1. 将默认AuthenticationManager(也可以定义的)设置到自定义的filter过滤器中

  2. 将自定义的UserDetailsService设置到自定义的AuthenticationProvide中以供使用

  3. 将过滤器添加到过滤链路中,实施过滤操作。(一般以加在UsernamePasswordAuthenticationFilter前)

配置SmsAuthenticationSecurityConfig:

 @Component
 public class SmsAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {    @Autowired
    private UserDetailsService userDetailsService;    @Override
    public void configure(HttpSecurity http) throws Exception {        //创建并配置好自定义SmsAuthenticationfilter,
        SmsAuthenticationfilter smsAuthenticationfilter = new SmsAuthenticationfilter();
        smsAuthenticationfilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
        smsAuthenticationfilter.setAuthenticationSuccessHandler(customAuthenticationSuccessHandler());
        smsAuthenticationfilter.setAuthenticationFailureHandler(customAuthenticationFailureHandler());        //创建并配置好自定义SmsAuthenticationProvide
        SmsAuthenticationProvide smsAuthenticationProvide=new SmsAuthenticationProvide();
        smsAuthenticationProvide.setUserDetailsService(userDetailsService);
        http.authenticationProvider(smsAuthenticationProvide);        //将过滤器添加到过滤链路中
        http.addFilterAfter(smsAuthenticationfilter, UsernamePasswordAuthenticationFilter.class);
    }    @Bean
    public CustomAuthenticationSuccessHandler customAuthenticationSuccessHandler() {        return new CustomAuthenticationSuccessHandler();
    }    
    @Bean
    public CustomAuthenticationFailureHandler customAuthenticationFailureHandler() {        return new CustomAuthenticationFailureHandler();
    }
}

5.2 SecurityConfig主配置

  SecurityConfig主配置可以参照第二节Spring Security(二)--WebSecurityConfigurer配置以及filter顺序进行配置。

SecurityConfig主配置:

@Configurationpublic class WebSecurityConfig extends WebSecurityConfigurerAdapter {    @Autowired
    private SmsAuthenticationSecurityConfig smsAuthenticationSecurityConfig;    @Autowired
    private CustomAuthenticationSuccessHandler authenticationSuccessHandler;    @Autowired
    private CustomAuthenticationFailureHandler authenticationFailureHandler;    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.headers().frameOptions().disable().and()
                .formLogin()
                .loginPage(SecurityConstants.APP_FORM_LOGIN_PAGE)                //配置form登陆的自定义URL
                .loginProcessingUrl(SecurityConstants.APP_FORM_LOGIN_URL)
                .successHandler(authenticationSuccessHandler)
                .failureHandler(authenticationFailureHandler)
                .and()                //配置smsAuthenticationSecurityConfig
                .apply(smsAuthenticationSecurityConfig)
                .and()                //运行通过URL
                .authorizeRequests()
                .antMatchers(SecurityConstants.APP_MOBILE_VERIFY_CODE_URL,
                             SecurityConstants.APP_USER_REGISTER_URL)
                .permitAll()
                .and()
                .csrf().disable();
    }    @Bean
    public ObjectMapper objectMapper(){        return new ObjectMapper();
    }
}

6.其他

6.1 redis

                redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
            } else {
                set(key, value);
            }            return true;
        } catch (Exception e) {
            e.printStackTrace();            return false;
        }
    }

}

7.总结

  可以根据短信验证登陆模式去实现类似的验证方式,可以结合本节的例子进行跟项目结合起来,减少开发时间。后续还有第三方登陆方式分析以案例。最后错误请评论指出!
