Question

我在代码如下的SecurityConfig类的configure方法中遇到错误：

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，错误在这里auth.authenticationProvider(authenticationProvider()); 代码正在正常编译，但是由于这个原因，我被禁止使用403。流量在这里被打破

    }

        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);

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

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

}

用户注册过程运行正常，但是由于上述代码，身份验证不起作用。我正在使用邮递员进行验证。不知道我正面临什么麻烦并且完全沮丧。
