此问题实际上与此问题有关problem

根据@ harsh-poddar的建议,我相应地添加了过滤器。

然而,在添加之后,即使使用有效的凭据,我似乎也无法登录。

以下是相关代码:

SecurityConfig

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

//  @Bean
//  public CustomAuthenticationEntryPoint customAuthenticationEntryPoint() {
//      return new CustomAuthenticationEntryPoint();
//  }

@Bean
public CustomExceptionTranslationFilter customExceptionTranslationFilter() {
    return new CustomExceptionTranslationFilter(new CustomAuthenticationEntryPoint());
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        //Note : Able to login without this filter, but after adding this, valid credential also fails
        .addFilterAfter(customExceptionTranslationFilter(), ExceptionTranslationFilter.class)
//      .exceptionHandling()
//          .authenticationEntryPoint(new customAuthenticationEntryPoint())
//          .and()
        .authorizeRequests()
            .anyRequest().authenticated()
            .and()
        .requestCache()
            .requestCache(new NullRequestCache())
            .and()
        .httpBasic()
            .and()
        .csrf().disable();
}

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(new CustomAuthenticationProvider());
    }
}

CustomAuthenticationProvider

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

public CustomAuthenticationProvider() {
    super();
}

@Override
public Authentication authenticate(final Authentication authentication) throws AuthenticationException  {
    final String name = authentication.getName();
    final String password = authentication.getCredentials().toString();
    if (name.equals("admin") && password.equals("password")) {
        final List<GrantedAuthority> grantedAuths = new ArrayList<>();
        grantedAuths.add(new SimpleGrantedAuthority("ROLE_USER"));
        final UserDetails principal = new User(name, password, grantedAuths);
        final Authentication auth = new UsernamePasswordAuthenticationToken(principal, password, grantedAuths);
        return auth;
    } else {
        throw new BadCredentialsException("NOT_AUTHORIZED");
    }
}

    @Override
    public boolean supports(final Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

CustomExceptionTranslationFilter

@Component
public class CustomExceptionTranslationFilter extends ExceptionTranslationFilter {

    public CustomExceptionTranslationFilter(AuthenticationEntryPoint authenticationEntryPoint) {
        super(authenticationEntryPoint);
    }
}

CustomAuthenticationEntryPoint

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException authException) throws IOException, ServletException {
        response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized.");
    }
}

AuthenticationEntryPoint的预期设计是启动/启动身份验证。但是,您的实施CustomAuthenticationEntryPoint不会这样做。相反,它只是发回未经授权的响应。有关实现细节的更多详细信息,请参阅AuthenticationEntryPoint的javadoc。

根据您的配置,您使用HTTP Basic进行身份验证:

protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .anyRequest().authenticated()
            .and()
        .httpBasic();
}

此特定配置将自动配置BasicAuthenticationEntryPoint,这是AuthenticationEntryPoint的实现。 BasicAuthenticationEntryPoint将根据server protocol向http {1}}的http响应标头提出质询,以进行身份​​验证。

但是,您正在配置自己的WWW-Authenticate: Basic realm="User Realm",它最终会覆盖CustomAuthenticationEntryPoint,这不是您想要做的。

other post建议使用此配置,这不再是您想要做的。

BasicAuthenticationEntryPoint

如果您的主要目标是在身份验证失败时向用户提供自定义响应,那么我建议使用已配置protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .httpBasic() .and() .exceptionHandling().authenticationEntryPoint(new CustomAuthenticationEntryPoint()); } 的表单登录配置。这是配置:

AuthenticationFailureHandler

http .authorizeRequests() .anyRequest().authenticated() .and() .formLogin().failureHandler(new DefaultAuthenticationFailureHandler()) .and() .csrf().disable(); // NOTE: I would recommend enabling CSRF 的实施将是:

DefaultAuthenticationFailureHandler

AuthenticationFailureHandler专门用于处理失败的身份验证尝试。
