Spring boot: Pourquoi utiliser OncePerRequestFilter?

J'ai une classe appelée JwtTokenAuthorizationOncePerRequestFilter où elle étend OncePerRequestFilter

Cependant, je rencontre un problème lorsque je me connecte, puis après une certaine utilisation de l'application Web

J'obtiens toujours "JWT_TOKEN_DOES_NOT_START_WITH_BEARER_STRING"

Voir le code ci-dessous:

package com.sbc.cpex.security.jwt;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

import io.jsonwebtoken.ExpiredJwtException;

@Component
public class JwtTokenAuthorizationOncePerRequestFilter extends OncePerRequestFilter {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private UserDetailsService jwtInMemoryUserDetailsService;

    @Autowired
    private JwtTokenUtil jwtTokenUtil;

    @Value("${jwt.http.request.header}")
    private String tokenHeader;

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException {
        logger.debug("Authentication Request For '{}'", request.getRequestURL());

        final String requestTokenHeader = request.getHeader(this.tokenHeader);

        String username = null;
        String jwtToken = null;
        if (requestTokenHeader != null && requestTokenHeader.startsWith("Bearer ")) {
            jwtToken = requestTokenHeader.substring(7);
            try {
                username = jwtTokenUtil.getUsernameFromToken(jwtToken);
            } catch (IllegalArgumentException e) {
                logger.error("JWT_TOKEN_UNABLE_TO_GET_USERNAME", e);
            } catch (ExpiredJwtException e) {
                logger.warn("JWT_TOKEN_EXPIRED", e);
            }
        } else {
            logger.warn("JWT_TOKEN_DOES_NOT_START_WITH_BEARER_STRING");
        }

        logger.debug("JWT_TOKEN_USERNAME_VALUE '{}'", username);
        if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {

            UserDetails userDetails = this.jwtInMemoryUserDetailsService.loadUserByUsername(username);

            if (jwtTokenUtil.validateToken(jwtToken, userDetails)) {
                UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
                usernamePasswordAuthenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
                SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
            }
        }

        chain.doFilter(request, response);
    }
}

Est-il possible pour moi de simplement déclencher cette classe lors de la connexion? Et pas lors de l'acceptation d'autres demandes

TIA
