【问题描述】：

我已经编写了一个 jwt 过滤器来执行数据库操作和控制获取的令牌，但是我扩展的 OncePerRequestFilter 在抛出异常时总是发送 http 状态 500“内部服务器错误”。我该如何解决？

    @Component
public class JwtTokenFilter extends OncePerRequestFilter 


    @Autowired
    private TokenManager tokenManager;

    private IgniteRepository repository;

    public JwtTokenFilter(IgniteRepository repository) 
        this.repository = repository;
    

    @Override
    protected void doFilterInternal(HttpServletRequest httpServletRequest,
                                    @NotNull HttpServletResponse httpServletResponse,
                                    @NotNull FilterChain filterChain) throws ServletException, IOException 

        //System.out.println(tokenManager.generateToken("qq"));
        String authorizationHeader = httpServletRequest.getHeader(HttpHeaders.AUTHORIZATION);

        if (Strings.isNullOrEmpty(authorizationHeader) || !authorizationHeader.startsWith("Bearer")) 
            throw new JwtNullException();//this is my own exception class and it sends 401
        

        String token = authorizationHeader.substring(7);
        String afId = tokenManager.getUsernameToken(token);
        repository.putCache(afId,new APIInvokerEnrolmentDetails());


        //System.out.println(afId+" "+token);
        if (!repository.containsAtCache(afId))
           throw new OnboardedAFException(); //this is my own exception class and it sends 403
        



        filterChain.doFilter(httpServletRequest, httpServletResponse);
    

【参考方案1】：

“500 internal”错误是服务器异常期间出现的消息。我认为您应该使用“try and catch”来生成这些错误并选择其返回状态。
