Getting problem authenticationProvider in jwt authorization - spring-boot

Question

I am getting error in configure method of SecurityConfig class whose code is here:
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();
}
}
in above code, error lies here auth.authenticationProvider(authenticationProvider());
code is getting compiled fine but due to this i am getting 403 forbidden. Flow is getting broken here
JwtAutheticationFilter class is here

}
}
JwtAuthorizationFilter class is here
package com.sumit.Security;
import static com.auth0.jwt.algorithms.Algorithm.HMAC512;

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;
}
}
User registration process is working fine but authentication is not working because of above mentioned code.
I am using postman to verify it.
Don't know what trouble i am facing and totally frustrated.
