spring-boot - 在 jwt 授权中获取问题 authenticationProvider

Question

我在 SecurityConfig 类的配置方法中遇到错误，其代码在这里：

package com.sumit.Security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

import com.sumit.Repo.UserRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    UserDetailsService userDetailsService;
    @Autowired
private UserRepository userRepository;



    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider());
        }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
           http
           // remove csrf and state in session because in jwt we do not need them
           .csrf().disable()
           .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
           .and()
           .addFilter(new JwtAuthenticationFilter(authenticationManager()))
           .addFilter(new JwtAuthorizationFilter(authenticationManager(),userRepository))
           .authorizeRequests()
           // configure access rules
           .antMatchers("/register").permitAll()
           .antMatchers("/admin").hasRole("ADMIN")
           .antMatchers("/user").hasAnyRole("ADMIN","USER")
           .antMatchers("/management").hasAnyRole("MANAGER","ADMIN")
           .antMatchers("/page1").hasAnyAuthority("ROLE_ADMIN","ACCESS_PAGE1")
           .antMatchers("/page2").hasAnyAuthority("ROLE_ADMIN","ACCESS_PAGE2")
           .anyRequest().authenticated();
//           .and()
//           .formLogin()
//           .loginPage("/login")
//           .usernameParameter("username")
//           .passwordParameter("password").successForwardUrl("/welcome")
//          .permitAll();


    }

    @Bean
    DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        daoAuthenticationProvider.setUserDetailsService(this.userDetailsService);
        return daoAuthenticationProvider;
    }



    @Bean
    PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

在上面的代码中，错误在于auth.authenticationProvider(authenticationProvider()); 代码编译得很好，但由于这个原因，我被 403 禁止。流程在这里被打破

JwtAutheticationFilter 类在这里

package com.sumit.Security;

import static com.auth0.jwt.algorithms.Algorithm.HMAC512;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Date;

import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

import com.auth0.jwt.JWT;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.sumit.Repo.UserRepository;


public class JwtAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    private AuthenticationManager authenticationManager;

    public JwtAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
            throws AuthenticationException {
        LoginModel credentials = null;
    try {
            credentials = new ObjectMapper().readValue(request.getInputStream(), LoginModel.class);
        } catch (Exception e) {
            e.printStackTrace();
        }

        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(
                credentials.getUsername(), credentials.getPassword(), new ArrayList<>());

        Authentication auth = authenticationManager.authenticate(usernamePasswordAuthenticationToken);
        return auth;
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain,
            Authentication authResult) throws IOException, ServletException {
        UserPrincipal principal = (UserPrincipal) authResult.getPrincipal();
        String token = JWT.create()
                .withSubject(principal.getUsername())
                .withExpiresAt(new Date(System.currentTimeMillis() + JWTProperties.EXPIRATION_TIME))
                .sign(HMAC512(JWTProperties.SECRET.getBytes()));

        response.addHeader(JWTProperties.HEADER_STRING, JWTProperties.TOKEN_PREFIX + token);
    }




}

JwtAuthorizationFilter 类在这里

package com.sumit.Security;

import static com.auth0.jwt.algorithms.Algorithm.HMAC512;

import java.io.IOException;

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

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;

import com.auth0.jwt.JWT;
import com.sumit.Repo.UserRepository;

public class JwtAuthorizationFilter extends BasicAuthenticationFilter {
    @Autowired
private UserRepository userRepository;
    public JwtAuthorizationFilter(AuthenticationManager authenticationManager,UserRepository userRepository
            ) {
        super(authenticationManager);

    }

    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {
        // Read the Authorization header, where the JWT token should be
        String header = request.getHeader(JWTProperties.HEADER_STRING);

        // If header does not contain BEARER or is null delegate to Spring impl and exit
        if (header == null || !header.startsWith(JWTProperties.TOKEN_PREFIX)) {
            chain.doFilter(request, response);
            return;
        }

        // If header is present, try grab user principal from database and perform authorization
        Authentication authentication = getUsernamePasswordAuthentication(request);
        SecurityContextHolder.getContext().setAuthentication(authentication);

        // Continue filter execution
        chain.doFilter(request, response);
    }

    private Authentication getUsernamePasswordAuthentication(HttpServletRequest request) {
        String token = request.getHeader(JWTProperties.HEADER_STRING)
                .replace(JWTProperties.TOKEN_PREFIX,"");

        if (token != null) {
            // parse the token 
            String userName = JWT.require(HMAC512(JWTProperties.SECRET.getBytes()))
                    .build()
                    .verify(token)
                    .getSubject();

               if (userName != null) {
                User user = userRepository.findByUsername(userName);
                UserPrincipal principal = new UserPrincipal(user);
                UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(userName, null, principal.getAuthorities());
                return auth;
            }
            return null;
        }
        return null;
    }

}

用户注册过程正常，但由于上述代码，身份验证不起作用。我正在使用邮递员来验证它。不知道我面临什么麻烦，完全沮丧。
