Question

这是我的主要应用程序配置

@SpringBootApplication
public class Application {

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

这是我的spring security应用程序配置。

@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");
    }
}

这是我的TokenProcessingFilter，它为我的自定义身份验证过滤器扩展了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);
    }
}

然而，在运行应用程序时，我遇到此异常消息。我错过了什么？

运行时发生异常。 null：InvocationTargetException：无法启动嵌入式容器;嵌套异常是 org.springframework.boot.context.embedded.EmbeddedServletContainerException：无法启动嵌入式Tomcat：使用名称创建bean时出错 'tokenProcessingFilter'在文件中定义 [C：\用户\ kyel \项目\应用\目标\类\有机\应用\ testapp \安全\ TokenProcessingFilter.class]：调用init方法失败;嵌套异常是 java.lang.IllegalArgumentException：authenticationManager必须是指定的

Answer 1

您需要在AuthenticationManager上设置TokenProcessingFilter。而不是在TokenProcessingFilter上使用@Component，只需在SecurityConfig中创建它。

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

和

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

Answer 2

为了保留Component注释，您必须从AbstractAuthenticationProcessingFilter覆盖setAuthenticationManager并像这样自动连接参数：

@Component
public class TokenProcessingFilter extends UsernamePasswordAuthenticationFilter {

    //...

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

    //...

}

Spring启动安全配置 - 必须指定authenticationManager
