运行时未调用自定义弹簧安全过滤器

Question

我正在尝试在 Spring Boot Rest 服务项目中启用 Spring Security，但遇到了一些问题。

我用这段代码配置了它

@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    private LdapAuthenticationProvider ldapAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .httpBasic().and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }


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

        auth.authenticationProvider(ldapAuthenticationProvider);
    }

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

}

并实现了一个自定义身份验证提供程序以登录 LDAP（它具有非标准配置，因此我无法使默认 ldap 提供程序工作）

@Component
public class LdapAuthenticationProvider implements AuthenticationProvider {

    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {

        String email = authentication.getName();
        String password = authentication.getCredentials().toString();

        LdapConnection ldap = new LdapConnection();
        String uid = ldap.getUserUID(email);
        if(uid == null || uid == ""){
            throw new BadCredentialsException("User " + email + " not found");
        }

        if(ldap.login(uid, password)){

            return new UsernamePasswordAuthenticationToken(uid, null, new ArrayList<>());
        }else{
            throw new BadCredentialsException("Bad credentials");
        }
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return true;  
        //To indicate that this authenticationprovider can handle the auth request. since there's currently only one way of logging in, always return true

    }

}

这段代码运行良好，因为使用基本授权标头调用我的服务，它能够正确登录并返回调用的服务。当我尝试插入不同的授权/身份验证时，问题就开始了。我不想使用基本身份验证，而是想从我的反应前端中的表单传递凭据，所以我想在 POST 调用中将它们作为 json 主体传递。 （想法是生成一个 jwt 令牌并将其用于以下通信）。

所以我把configure方法改成这样：

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .addFilter(new JWTAuthenticationFilter(authenticationManager()))
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

并定义了一个自定义身份验证过滤器：

public class JWTAuthenticationFilter extends
        UsernamePasswordAuthenticationFilter {

    @Autowired
    private AuthenticationManager authenticationManager;

    public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res) throws AuthenticationException{
        String requestBody;
        try{
            requestBody = IOUtils.toString(req.getReader());
            JsonParser jsonParser = JsonParserFactory.getJsonParser();
            Map<String, Object> requestMap = jsonParser.parseMap(requestBody);
            return authenticationManager.authenticate( new UsernamePasswordAuthenticationToken(requestMap.get("email"), requestMap.get("password"), new ArrayList<>()));
        }catch(IOException e){
            throw new InternalAuthenticationServiceException("Something goes wrong parsing the request body",e );
        }
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest req, HttpServletResponse res, FilterChain chain, Authentication auth) throws IOException{

        JwtTokenProvider tokenProvider = new JwtTokenProvider();
        String token = tokenProvider.generateToken(auth.getPrincipal().toString());
        Cookie cookie = new Cookie("jwt",token);
        cookie.setHttpOnly(true);
        cookie.setSecure(true);
        res.addCookie(cookie);

    }

}

问题是，无论我在做什么，运行时似乎根本没有进入这个过滤器。我错过了什么？我想这是一件又大又愚蠢的事情，但我想不通......

更新：问题似乎是 UsernamePassWordAuthenticationFilter 只能通过表单调用。然后，我将代码更改为扩展 AbstractAuthenticationProcessingFilter。

修改后的过滤器：

public class JWTAuthenticationFilter extends
        AbstractAuthenticationProcessingFilter {


    private AuthenticationManager authenticationManager;

    public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
        super("/api/secureLogin");
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res) throws AuthenticationException{
        String requestBody;
        try{
            requestBody = IOUtils.toString(req.getReader());
            JsonParser jsonParser = JsonParserFactory.getJsonParser();
            Map<String, Object> requestMap = jsonParser.parseMap(requestBody);
            UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(requestMap.get("email"), requestMap.get("password"), new ArrayList<>()); 
            return authenticationManager.authenticate(token);
        }catch(IOException e){
            throw new InternalAuthenticationServiceException("Something goes wrong parsing the request body",e );
        }
    }
}

以及修改后的配置方法：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable().authorizeRequests()
        .antMatchers(HttpMethod.POST, "/api/secureLogin").permitAll()
        .antMatchers(HttpMethod.GET, "/api").permitAll()
        .antMatchers("/api/**").authenticated()
        .and()
        .addFilterBefore(new JWTAuthenticationFilter(authenticationManager()), UsernamePasswordAuthenticationFilter.class)
        .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}

Answer 1

我看到您在覆盖配置方法时添加了配置，请尝试在您的 web.xml 中添加过滤器映射。在“web-app”节点下是这样的：

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter>
    <filter-name>JWTAuthenticationFilter</filter-name>
    <filter-class>com.yourProject.JWTAuthenticationFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>JWTAuthenticationFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Answer 2

您希望通过访问路径api/secureLogin 来触发过滤器。默认情况下，UsernamePasswordAuthenticationFilter 仅通过访问 /login 触发。

如果您在扩展 UsernamePasswordAuthenticationFilter 的 JWTAuthenticationFilter 的构造函数中添加以下行，它应该可以工作：

  this.setFilterProcessesUrl("/api/secureLogin");

Answer 3

嗨@Mikyjpeg

您可以使用 UsernamePassWordAuthenticationFilter。不必像您提到的那样从表单中调用它。

只要通过带有/login url（而不是你的api/secureLogin url）的POST 方法调用它，它就会被执行。

构造函数使用了一个请求匹配器，它只允许这个 url & request 方法：

public UsernamePasswordAuthenticationFilter() {
  super(new AntPathRequestMatcher("/login", "POST"));
}

Answer 4

ADAM 的回答对我有用。那些正在使用基于注释的配置的人可以添加以下内容

@Override protected Filter[] getServletFilters() {
   return new Filter[]{
        new JwtAuthenticationFilter()
   }; 
}

在您的 AppInitialiser 中扩展 AbstractAnnotationConfigDispatcherServletInitializer

Answer 5

public class BeforeAuthenticationFilter extends AbstractAuthenticationProcessingFilter {

    public BeforeAuthenticationFilter() {
        super(new AntPathRequestMatcher("api/secureLogin", "POST"));
        super.setFilterProcessesUrl("api/secureLogin");
    }
