At the moment, I have SpringBoot 3.3.0-SPANSHOT installed. But my old version is written in the code – 2.7.5. My goal is to update the latest version of SpringBoot and redo the code in a new way (except for authorization/registration). But I decided to copy the authorization/registration (JWT) from an old project that is not stable.

JwtConfigurer.java

package com.pzh.WebCore.security.jwt;


import org.springframework.security.config.annotation.SecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.DefaultSecurityFilterChain;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

public class JwtConfigurer extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    private JwtTokenProvider jwtTokenProvider;

    public JwtConfigurer(JwtTokenProvider jwtTokenProvider) {
        this.jwtTokenProvider = jwtTokenProvider;
    }

    @Override
    public void configure(HttpSecurity httpSecurity) throws Exception {
        JwtTokenFilter jwtTokenFilter = new JwtTokenFilter(jwtTokenProvider);
        httpSecurity.addFilterBefore(jwtTokenFilter, UsernamePasswordAuthenticationFilter.class);
    }

}

JwtTokenFilter.java

package com.pzh.WebCore.security.jwt;

import jakarta.servlet.FilterChain;
import jakarta.servlet.ServletException;
import jakarta.servlet.ServletRequest;
import jakarta.servlet.ServletResponse;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.web.filter.GenericFilterBean;

import java.io.IOException;

public class JwtTokenFilter extends GenericFilterBean {

    private JwtTokenProvider jwtTokenProvider;

    public JwtTokenFilter(JwtTokenProvider jwtTokenProvider) {
        this.jwtTokenProvider = jwtTokenProvider;
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain filterChain)
            throws IOException, ServletException {

        String token = jwtTokenProvider.resolveToken((HttpServletRequest) req);
        if (token != null && jwtTokenProvider.validateToken(token)) {
            Authentication auth = jwtTokenProvider.getAuthentication(token);

            if (auth != null) {
                SecurityContextHolder.getContext().setAuthentication(auth);
            }
        }
        filterChain.doFilter(req, res);
    }

}
