我正在尝试创建一个主要使用
Spring访问REST API的应用程序,并尝试配置安全端.尝试使用此图片显示应用程序的实际结构：

>请求可以从任何平台到“abc.com/rest_api/”
>请求将发送到第3点或第5点.如果用户已通过用户名和密码进行身份验证,则将针对令牌验证请求,否则将重定向到数据库.
>如果必须通过数据库对用户名和密码进行身份验证,则会生成令牌并作为响应发回.
>之后,只有基于令牌的身份验证才有效.

我试图创建一个基本结构,我认为必须犯一个小错误,因为它没有按预期工作.

@Configuration
@EnableWebSecurity
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(securedEnabled=true, prePostEnabled=true)
public class UserDetailsSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired

    @Autowired
    private NHttpServletRequestBinder<Authentication> authenticationBinder;

                .usersByUsernameQuery(DEF_USERS_BY_USERNAME_QUERY).
                authoritiesByUsernameQuery(DEF_GROUP_AUTHORITIES_BY_USERNAME_QUERY).

        try {


             DataSource dataSource = (DataSource) new InitialContext().lookup("DS");
            return dataSource;

        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

      @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

      @Override
    protected void configure(HttpSecurity http) throws Exception {


                // The http.formLogin().defaultSuccessUrl("/path/") method is required when using stateless Spring Security
        // because the session cannot be used to redirect to the page that was requested while signed out. Unfortunately
        // using this configuration method will cause our custom success handler (below) to be overridden with the
        // default success handler. So to replicate the defaultSuccessUrl("/path/") configuration we will instead
        // correctly configure and delegate to the default success handler.
        final SimpleUrlAuthenticationSuccessHandler delegate = new SimpleUrlAuthenticationSuccessHandler();
        delegate.setDefaultTargetUrl("/api/");
          // Make Spring Security stateless. This means no session will be created by Spring Security, nor will it use any
        // previously existing session.
        http.sessionManagement().sessionCreationPolicy(STATELESS);
        // Disable the CSRF prevention because it requires the session, which of course is not available in a
        // stateless application. It also greatly complicates the requirements for the sign in POST request.
        http.csrf().disable();
        // Viewing any page requires authentication.
        http.authorizeRequests().anyRequest().authenticated();
        http
          .formLogin().loginPage("http://localhost/web/ui/#access/signin")
          .permitAll()
            // Override the sign in success handler with our stateless implementation. This will update the response
            // with any headers and cookies that are required for subsequent authenticated requests.
            .successHandler(new NStatelessAuthenticationSuccessHandler(authenticationBinder, delegate));
        http.logout().logoutUrl("http://localhost/web/ui/#access/signin").logoutSuccessUrl("http://localhost/web/ui/#access/signin");
        // Add our stateless authentication filter before the default sign in filter. The default sign in filter is
        // still used for the initial sign in, but if a user is authenticated we need to acknowledge this before it is
        // reached.
        http.addFilterBefore(
            new StatelessAuthenticationFilter(authenticationBinder, securityContextHolder),
            UsernamePasswordAuthenticationFilter.class
        );

} 

}

我有两种类型的authenticationBinder,即TokenBased和UserNameBased.

TokenBased：

@Component
public class NXAuthTokenHttpServletRequestBinder implements NHttpServletRequestBinder<String> {

    private static final String X_AUTH_TOKEN = "X-AUTH-TOKEN";
    private final NTokenFactory tokenFactory;

    @Autowired
    public NXAuthTokenHttpServletRequestBinder(NTokenFactory tokenFactory) {
        this.tokenFactory = tokenFactory;
    }

    @Override
    public void add(HttpServletResponse response, String username) {

        final String token = tokenFactory.create(username);

        response.addHeader(X_AUTH_TOKEN, token);
        response.addCookie(new Cookie(X_AUTH_TOKEN, token));
    }

    @Override
    public String retrieve(HttpServletRequest request) {

        final String cookieToken = findToken(request);

        if (cookieToken != null) {
            return tokenFactory.parseUsername(cookieToken);
        }

        return null;
    }

    private static String findToken(HttpServletRequest request) {
        Enumeration<String> it = request.getHeaderNames();
        while(it.hasMoreElements()){
            System.out.println(it.nextElement());
        }
        final String headerToken = request.getHeader(X_AUTH_TOKEN);

        if (headerToken != null) {
            return headerToken;
        }

        final Cookie[] cookies = request.getCookies();

        if (cookies != null) {
            for (Cookie cookie : cookies) {
                if (X_AUTH_TOKEN.equals(cookie.getName())) {
                    return cookie.getValue();
                }
            }
        }

        return null;
    }
}

基于用户：

@Component
@Primary
public class NUserAuthenticationFactory implements NHttpServletRequestBinder<Authentication> {

    private final NHttpServletRequestBinder<String> httpServletRequestBinder;

    @Autowired

    public NUserAuthenticationFactory(NHttpServletRequestBinder<String> httpServletRequestBinder) {
        this.httpServletRequestBinder = httpServletRequestBinder;
    }

    @Override
    public void add(HttpServletResponse response, Authentication authentication) {
        httpServletRequestBinder.add(response, authentication.getName());
    }

    @Override
    public UserAuthentication retrieve(HttpServletRequest request) {

        final String username = httpServletRequestBinder.retrieve(request);

        if (username != null) {

            return new UserAuthentication(new CustomJDBCDaoImpl().loadUserByUsername(username));
        }

        return null;
    }
}

问题
每当我加载我的应用程序时,它都会进入基于UserBased的身份验证,然后尝试从令牌获取用户名,而不是从数据库验证它.但是,那时没有令牌,因为这是我从UI发出的第一个帖子请求.它将我重定向回相同的登录页面.

最佳答案 逐步解决您的问题可以..

>使用spring security UsernamePasswordAuthenticationFilter通过用户名和密码对用户进行身份验证,并生成唯一令牌.
>编写另一个自定义安全筛选器和AuthenticationProvider实现,以对连续请求的用户进行身份验证.
>将自定义安全过滤器置于UsernamePasswordAuthenticationFilter中,如下所示

http.addFilterBefore(CustomTokenBasedAuthenticationFilter,UsernamePasswordAuthenticationFilter.class);
>使用AuthenticationManager注册AuthenticationProvider实现
>那就是它！

注意： – 保护其余API的更好方法是使用一些标准协议,如oauth1a,oauth2.0等.Spring提供了oauth1a和oauth2.0协议的新颖实现.
