Spring boot 安全配置 - 必須指定 authenticationManager

Question

這是我的主要應用程序配置

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        new SpringApplicationBuilder(Application.class)
                .banner((environment, aClass,  printStream) ->
                        System.out.println(stringBanner()))
                .run();
    }
}

這是我的 spring 安全應用程序配置。

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private WebServiceAuthenticationEntryPoint unauthorizedHandler;

    @Autowired
    private TokenProcessingFilter authTokenProcessingFilter;

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf()
                .disable()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS) // Restful hence stateless
                .and()
                .exceptionHandling()
                .authenticationEntryPoint(unauthorizedHandler) // Notice the entry point
                .and()
                .addFilter(authTokenProcessingFilter) // Notice the filter
                .authorizeRequests()
                .antMatchers("/resources/**", "/api/auth")
                .permitAll()
                .antMatchers("/greeting")
                .hasRole("USER");
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .inMemoryAuthentication()
                .withUser("user")
                .password("password")
                .roles("USER");
    }
}

這是我的 TokenProcessingFilter，它為我的自定義身份驗證過濾器擴展了 UsernamePasswordAuthenticationFilter

@Component
public class TokenProcessingFilter extends UsernamePasswordAuthenticationFilter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = this.getAsHttpRequest(request);
        String authToken = this.extractAuthTokenFromRequest(httpRequest);
        String userName = TokenUtils.getUserNameFromToken(authToken);
        if (userName != null) {/*
            UserDetails userDetails = userDetailsService.loadUserByUsername(userName);*/
            UserDetails userDetails = fakeUserDetails();
            if (TokenUtils.validateToken(authToken, userDetails)) {
                UsernamePasswordAuthenticationToken authentication =
                        new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword(), userDetails.getAuthorities());
                authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpRequest));
                SecurityContextHolder.getContext().setAuthentication(authentication);
                Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
            }
        }
        chain.doFilter(request, response);
    }

    private HttpServletRequest getAsHttpRequest(ServletRequest request){
        if (!(request instanceof HttpServletRequest)) {
            throw new RuntimeException("Expecting an HTTP request");
        }
        return (HttpServletRequest) request;
    }


    private String extractAuthTokenFromRequest(HttpServletRequest httpRequest) {
        /* Get token from header */
        String authToken = httpRequest.getHeader("x-auth-token");
        /* If token not found get it from request parameter */
        if (authToken == null) {
            authToken = httpRequest.getParameter("token");
        }
        return authToken;
    }

    private UserDetails fakeUserDetails(){
        UsernamePasswordAuthenticationToken authenticationToken = new
                UsernamePasswordAuthenticationToken("user","password");

        List<SimpleGrantedAuthority> auth= new ArrayList<>();
        auth.add(new SimpleGrantedAuthority("USER"));
        return  new User("user","password",auth);
    }
}

但是，在運行應用程序時，我遇到了此異常消息。 我錯過了什么？

運行時發生異常。 null：InvocationTargetException：無法啟動嵌入式容器； 嵌套異常是 org.springframework.boot.context.embedded.EmbeddedServletContainerException：無法啟動嵌入式 Tomcat：在文件 [C:\\Users\\kyel\\projects\\app\\target\\classes\\org\\ app\\testapp\\security\\TokenProcessingFilter.class]：調用init方法失敗； 嵌套異常是 java.lang.IllegalArgumentException：必須指定 authenticationManager

Answer 1

您需要在TokenProcessingFilter上設置AuthenticationManager 。 不要在 TokenProcessingFilter 上使用 @Component，只需在 SecurityConfig 中創建它。

@Bean
TokenProcessingFilter tokenProcessingFilter() {
  TokenProcessingFilter tokenProcessingFilter = new TokenProcessingFilter();
  tokenProcessingFilter.setAuthenticationManager(authenticationManager());
  return tokenProcessingFilter;
}

和

protected void configure(HttpSecurity http) throws Exception {
  ...
  .addFilter(tokenProcessingFilter())

Answer 2

為了保持組件注釋，您必須從 AbstractAuthenticationProcessingFilter 覆蓋 setAuthenticationManager 並像這樣自動裝配參數：

@Component
public class TokenProcessingFilter extends UsernamePasswordAuthenticationFilter {

    //...

    @Override
    @Autowired
    public void setAuthenticationManager(AuthenticationManager authenticationManager) {
        super.setAuthenticationManager(authenticationManager);
    }

    //...

}
