我正在使用 Spring Secuity 开发一个应用程序，其中有一些自定义过滤器，但我无法正确配置它们。考虑以下自定义过滤器：

LoginAuthenticationFilter：

package com.espiritware.opusclick.restfullbackend.security.filters;


public class LoginAuthenticationFilter extends OncePerRequestFilter
    
    private static final String TOKEN_PREFIX = "Bearer ";
    private static final String HEADER_STRING = "Authorization";
    private String credentialsCharset = "UTF-8";

    @Autowired
    private AuthenticationManager authenticationManager;
    
    @Autowired
    private TokenService tokenService;
    
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException 
        
        String header = request.getHeader("Authorization");
        
        if (header == null || !header.startsWith("Basic ")) 
            filterChain.doFilter(request, response);
            return;
        
        
        String[] tokens = extractAndDecodeHeader(header, request);
        String email = tokens[0];
        String password = tokens[1];
        
        
        if(request.getServletPath().equals("/login/user")) 
            LoginAuthenticationFilter opusClickAuth= new OpusClickLoginAuthentication(email,password,true);
            try 
                Authentication result=authenticationManager.authenticate(opusClickAuth);
                if(result.isAuthenticated()) 
                    //SecurityContextHolder.getContext().setAuthentication(result);
                    String jwtToken=tokenService.createAuthenticationToken(result,true);
                    response.addHeader("Access-Control-Expose-Headers", "Authorization");
                    response.addHeader(HEADER_STRING, TOKEN_PREFIX + jwtToken);
                    response.setHeader("Content-Type", "application/json");
                
            catch(AuthenticationException failed) 
                //SecurityContextHolder.clearContext();
                response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
            
        
        else 
            LoginAuthenticationFilter opusClickAuth= new OpusClickLoginAuthentication(email,password,false);
            try 
                Authentication result=authenticationManager.authenticate(opusClickAuth);
                if(result.isAuthenticated()) 
                    //SecurityContextHolder.getContext().setAuthentication(result);
                    String jwtToken=tokenService.createAuthenticationToken(result,false);
                    response.addHeader("Access-Control-Expose-Headers", "Authorization");
                    response.addHeader(HEADER_STRING, TOKEN_PREFIX + jwtToken);
                    response.setHeader("Content-Type", "application/json");
                
            catch(AuthenticationException failed) 
                //SecurityContextHolder.clearContext();
                response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
            
        
    
    
    protected String[] extractAndDecodeHeader(String header, HttpServletRequest request)
            throws IOException 

        byte[] base64Token = header.substring(6).getBytes("UTF-8");
        byte[] decoded;
        try 
            decoded = Base64.getDecoder().decode(base64Token);
        
        catch (IllegalArgumentException e) 
            throw new BadCredentialsException(
                    "Failed to decode basic authentication token");
        

        String token = new String(decoded, getCredentialsCharset(request));

        int delim = token.indexOf(":");

        if (delim == -1) 
            throw new BadCredentialsException("Invalid basic authentication token");
        
        return new String[]  token.substring(0, delim), token.substring(delim + 1) ;
    
    
    protected String getCredentialsCharset(HttpServletRequest httpRequest) 
        return this.credentialsCharset;
    
    
    
    //No debe filtrar
    //false -> se activa
    //true -> no se activa
    @Override
    protected boolean shouldNotFilter(HttpServletRequest request) throws ServletException 
        if(request.getServletPath().equals("/login/user")|| request.getServletPath().equals("/login/expert"))
            return false;
        
        else 
            return true;

JwtAuthenticationFilter：

package com.espiritware.opusclick.restfullbackend.security.filters;

public class JwtAuthenticationFilter extends OncePerRequestFilter
    
    @Autowired
    private AuthenticationManager authenticationManager;
    
    @Autowired
    private TokenService tokenService;

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException 
        
        String header = request.getHeader("Authorization");
        
        if (header == null || !header.startsWith("Bearer ")) 
            filterChain.doFilter(request, response);
            return;
        
        
        String jwtToken=extractToken(header);
        JwtAuthentication jwtAuthentication = new JwtAuthentication(jwtToken);
        
        try 
            Authentication result=authenticationManager.authenticate(jwtAuthentication);
            SecurityContextHolder.getContext().setAuthentication(result);
            filterChain.doFilter(request, response);
        catch(AuthenticationException failed) 
            SecurityContextHolder.clearContext();
            response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        
        authenticationManager.authenticate(jwtAuthentication);
    
    
    protected String extractToken(String header)

        int delim = header.indexOf(" ");

        if (delim == -1) 
            throw new BadCredentialsException("Invalid authentication token");
        
        return header.substring(delim + 1);
    
    
    
    @Override
    protected boolean shouldNotFilter(HttpServletRequest request) throws ServletException 
        if(request.getServletPath().equals("/login/user")|| request.getServletPath().equals("/login/expert"))
            return true;
        
        else 
            return false;

过滤器配置：

package com.espiritware.opusclick.restfullbackend.security.filters.configurations;
@Configuration
public class FilterConfigurations 
    
    @Bean
    public LoginAuthenticationFilter opusClickLoginAuthenticationFilter() 
        return new OpusClickLoginAuthenticationFilter();
    
    
    @Bean
    public JwtAuthenticationFilter jwtAuthenticationFilter() 
        return new JwtAuthenticationFilter();

WebAppSecurityConfiguration：（失败）

package com.espiritware.opusclick.restfullbackend.security;

@Configuration
public class WebAppSecurityConfiguration extends WebSecurityConfigurerAdapter 
        
    @Autowired
    private LoginAuthenticationFilter opusClickLoginAuthenticationFilter;
    
    @Autowired
    private JwtAuthenticationFilter jwtAuthenticationFilter;
    
     @Override
     protected void configure(HttpSecurity http) throws Exception 
         //http.oauth2Client();
         http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
         
         http.addFilterAt(LoginAuthenticationFilter,
                    BasicAuthenticationFilter.class)
              .addFilterAt(jwtAuthenticationFilter, 
                    BasicAuthenticationFilter.class);
         
         http.authorizeRequests()
                .anyRequest()
                .authenticated()
            .and()  
                .httpBasic();
         
         
     
     
     
    @Bean
    public PasswordEncoder passwordEncoder() 
        return new BCryptPasswordEncoder();
    
    
//  @Bean
//  public LoginAuthenticationFilter LoginAuthenticationFilter() 
//      return new LoginAuthenticationFilter();
//  
    
//  @Bean
//  public JwtAuthenticationFilter jwtAuthenticationFilter() 
//      return new JwtAuthenticationFilter();
//  
    
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception 
        return super.authenticationManagerBean();

当我运行应用程序时，它会抛出以下异常：

但是，当我评论整个 FilterConfigurations 类并直接在 WebAppSecurityConfiguration 中配置过滤器 bean 时，它可以正常工作：

WebAppSecurityConfiguration：（正常工作）

package com.espiritware.opusclick.restfullbackend.security;

@Configuration
public class WebAppSecurityConfiguration extends WebSecurityConfigurerAdapter 
        
    //@Autowired
    //private LoginAuthenticationFilter opusClickLoginAuthenticationFilter;
    
    //@Autowired
    //private JwtAuthenticationFilter jwtAuthenticationFilter;
    
     @Override
     protected void configure(HttpSecurity http) throws Exception 
         //http.oauth2Client();
         http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
         
         http.addFilterAt(LoginAuthenticationFilter(),
                    BasicAuthenticationFilter.class)
              .addFilterAt(jwtAuthenticationFilter(), 
                    BasicAuthenticationFilter.class);
         
         http.authorizeRequests()
                .anyRequest()
                .authenticated()
            .and()  
                .httpBasic();
         
         
     
     
     
    @Bean
    public PasswordEncoder passwordEncoder() 
        return new BCryptPasswordEncoder();
    
    
    @Bean
    public LoginAuthenticationFilter LoginAuthenticationFilter() 
        return new LoginAuthenticationFilter();
    
    
    @Bean
    public JwtAuthenticationFilter jwtAuthenticationFilter() 
        return new JwtAuthenticationFilter();
    
    
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception 
        return super.authenticationManagerBean();

我的问题是，当我在 FilterConfigurations 中执行 相同的配置 时，为什么会停止工作。我不知道是不是因为这个类在另一个包中找到。谁能解释这种奇怪行为的原因？

非常感谢！

【问题讨论】：

我认为LoginAuthenticationFilter和JwtAuthenticationFilter类也需要用@Configuration注解。请检查这是否有效。这两个过滤器都是不必要的，因为 spring security 已经支持基本登录（base64 enc 标头）并且已经在 spring security 5 @987654321 中实现了一个 JWTFilter @我不明白使用框架的意义如果你打算构建已经在框架中的东西？ 【参考方案1】：

要消除此问题，您必须在 WebSecurity 类之外创建一个 bean，因为我注意到 @autowired 和 @bean 有时会被容器搞砸，原因是他无法在运行时识别对象。

    @Component
public class PasswordEncoderConfiguration 

    @Bean
    BCryptPasswordEncoder passwordEncoder()
        return new BCryptPasswordEncoder();

您必须使用下面的方法将其自动连接到 Websecurityconfig 类，

@Autowired
private BCryptPasswordEncoder passwordEncoder;

    @Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception 
    // configure AuthenticationManager so that it knows from where to load
    // user for matching credentials
    // Use BCryptPasswordEncoder
    auth.userDetailsService(jwtUserDetailsService).passwordEncoder(passwordEncoder);

【讨论】：

【参考方案2】：

问题肯定与两个注释有关：@Autowired 用于过滤器，@Bean 注释用于authenticationManagerBean 方法。首先需要了解WebAppSecurityConfiguration 类将在两个过滤器都被自动装配时准备好使用，但是为了成功自动装配两个过滤器与AuthenticationManager 有关系，并且对于那个目标，我们通过@Bean 注释标记了方法authenticationManagerBean ，并且 Spring 尝试通过以下方式创建 AuthenticationManager：

public AuthenticationManager authenticationManagerBean() throws Exception 
    return new AuthenticationManagerDelegator(this.authenticationBuilder, this.context);

正如您在创建AuthenticationManagerDelegator 时看到的那样，我们应该已经初始化了两个字段authenticationBuilder 和context，但是我们刚刚开始创建我们的WebAppSecurityConfiguration 配置bean，它将被标记为创建时，直到所有字段都被初始化，它是专门为避免使用未初始化的字段和获得NullPointerException 异常而设计的。但是如果查看 bean 定义的第二个选项，bean 创建的工作流程发生了如下变化：

WebAppSecurityConfiguration

in creation

@Bean

authenticationManagerBean

WebAppSecurityConfiguration

附：从我的角度来看，通过以下方式定义 bean：

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

这不是一个好主意，因为WebSecurityConfigurerAdapter 类将按正确的顺序创建所有必需的组件（bean），并且父类中的这些方法已打开以通过以下方式自定义实现 bean：

@Override
public AuthenticationManager authenticationManagerBean() throws Exception 
    return new CustomAuthenticationManager(...);

【讨论】：

这是完美的解释。理想情况下，我们不应该在 Configuration 类中使用 Autowired，因为 Configuration 类用于 bean 定义和布线，所以很明显，当 spring 执行 bean 布线时，它不能注入 Autowired 对象，这些对象可能具有尚未初始化的依赖对象，并且它给出了 InCreationException。 【参考方案3】：

@Configuration 是给 Bean 配置的，不能用 @Autowired 自动注入普通的 bean，好像只支持这两种注入 1)@Value("$bean.name") String beanName; 2)@Inject 环境环境；环境是春天的特殊豆

WebAppSecurityConfiguration 更像是一个@Component Bean，而不是@Configuration Bean，你可以将@Component 和@Autowired 一起使用来注入过滤器Bean。

@Configuration 仅用于 Bean 配置，如果 DemoService 有 @Service 注解，则可以在 @Configuration 类中以这种方式注入它

@Bean
public JwtAuthenticationFilter jwtAuthenticationFilter(DemoService demoService) 
    return new JwtAuthenticationFilter(demoService);

【讨论】：

是的。我可以使用“@Autowired”在我的带注释的“@configuration”类中自动注入公共bean，这个工作正常。例如，如果我想在同一个类中使用“@Autowired”配置身份验证提供程序。例如，这对我有用：

@Configuration public class WebAppSecurityConfiguration extends WebSecurityConfigurerAdapter  @Autowired private JwtAuthenticationProvider jwtAuthenticationProvider; @Override protected void configure(AuthenticationManagerBuilder auth)  auth.authenticationProvider(jwtAuthenticationProvider);
