每个异常都会发送内部服务器错误

问题描述

我已经编写了一个jwt过滤器，用于执行数据库操作和控制采用的令牌，但是引发异常时，我扩展的OncePerRequestFilter始终发送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);
    }
}

解决方法

“ 500 internal”错误是服务器异常期间发生的消息。我认为您应该使用“尝试并捕获”来生成这些错误并选择其返回状态。
