可以扩展AuthenticationEntrypoint并实现Commence方法来处理复杂的AuthenticationException错误，如下所示：

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {

@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {

    if (authException instanceof InsufficientAuthenticationException) {
        response.sendRedirect("/login");
    } else if (authException instanceof AccountExpiredException) {
        response.sendRedirect("/account-expired");
    } else if (authException instanceof CredentialsExpiredException) {
        response.sendRedirect("/credentials-expired");
    } else if (authException instanceof DisabledException) {
        response.sendRedirect("/disabled");
    } else if (authException instanceof LockedException) {
        response.sendRedirect("/locked");
    } else {
        response.sendRedirect("/error");
    }

}

}

然后在Security配置类中使用CustomAuthenticationEntryPoint：

@Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private CustomAuthenticationEntryPoint customAuthenticationEntryPoint;

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.exceptionHandling()
        .authenticationEntryPoint(customAuthenticationEntryPoint)
        .accessDeniedPage("/403");

    // other configurations here
}

}

在这个示例中，我们可以通过检测不同的异常类型来处理不同的身份验证异常。根据需要进行更改以适应您的应用程序。
