JWT自定义筛选器中的Authentication Manager

public class JwtAuthenticationFilter extends OncePerRequestFilter {

    private AuthenticationManager authenticationManager;

    public JwtAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        String token = extractTokenFromRequest(request);

        if (token != null) {
            try {
                // 解析和验证JWT令牌
                JwtToken jwtToken = parseAndValidateToken(token);

                // 创建认证对象
                Authentication authentication = new JwtAuthentication(jwtToken);

                // 调用Authentication Manager进行身份验证
                Authentication authenticated = authenticationManager.authenticate(authentication);

                // 将认证对象添加到Spring Security的上下文中
                SecurityContextHolder.getContext().setAuthentication(authenticated);
            } catch (JwtException e) {
                // 处理令牌验证失败的情况
                handleTokenValidationFailure(response, e);
                return;
            }
        }

        filterChain.doFilter(request, response);
    }

    // 其他方法...
