[Solved] springsecurity custom exceptions: Error: Parse Error: Response overflow


In the process of writing the project, using springsecurity for permission management and customizing the token filter to be added before the authentication filter, there was a problem where the exception handling mechanism of springsecurity would be called when the token expired, instead of using my global exception handling


Custom filter

package com.fruiter.filter;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import io.jsonwebtoken.ExpiredJwtException;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

 * Handling exceptions thrown by Controller will be handled by this filter
public class ControllerExceptionFilter extends OncePerRequestFilter {

    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        try {
            filterChain.doFilter(request, response);
        } catch (ExpiredJwtException e) {


    public String convertObjectToJson(Object object) throws JsonProcessingException {
        if (object == null) {
            return null;
        ObjectMapper mapper = new ObjectMapper();
        return mapper.writeValueAsString(object);

Join for management

//WebAsyncManagerIntegrationFilter is the first exception handling filter
http.addFilterBefore(new ControllerExceptionFilter(), WebAsyncManagerIntegrationFilter.class);

be careful

Here, set the status code for response, that is, response.setStatus(401);
you can’t set an excessively large number such as 10010, otherwise an error will report error: parse error: response overflow

Modify it to 401.
