I want to implement Spring Security in my project. But I keep getting the same error no matter what I try.
I created necessary classes (TokenUtils, AuthenticationTokenFilter, SpringConfiguration). They are under the same package, but I'm getting the following error.
This is part of my Stack Trace where the problem occurs

Description:
Field tokenUtils in com.sbvtransport.sbvtransport.security.AuthenticationTokenFilter required a bean of type 'com.sbvtransport.sbvtransport.security.TokenUtils' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.sbvtransport.sbvtransport.security.TokenUtils' in your configuration.
package com.sbvtransport.sbvtransport.security;
These are my Security classes:
AuthenticationTokenFilter
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
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.UsernamePasswordAuthenticationFilter;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
public class AuthenticationTokenFilter extends UsernamePasswordAuthenticationFilter{
@Autowired
TokenUtils tokenUtils;
@Autowired
private UserDetailsService userDetailsService;
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
String authToken = httpRequest.getHeader("Authorization");
String username = tokenUtils.getUsernameFromToken(authToken);
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
if (tokenUtils.validateToken(authToken, userDetails)) {
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
userDetails, null, userDetails.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpRequest));
SecurityContextHolder.getContext().setAuthentication(authentication);
}
}
chain.doFilter(request, response);
}
}
TokenUtils
package com.sbvtransport.sbvtransport.security;
import java.util.Date;
import java.util.HashMap;

import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
public class TokenUtils {
@Value("SuperSecreat")
private String secret;
@Value("86400") // 24 hours(in seconds)
private Long expiration;
public String getUsernameFromToken(String token) {
String username;
try {
Claims claims = this.getClaimsFromToken(token);
username = claims.getSubject();
} catch (Exception e) {
username = null;
}
return username;
}
private Claims getClaimsFromToken(String token) {
Claims claims;
try {
claims = Jwts.parser().setSigningKey(this.secret).parseClaimsJws(token).getBody();
} catch (Exception e) {
claims = null;
}
return claims;
}
public Date getExpirationDateFromToken(String token) {
Date expirationDate;
try {
final Claims claims = this.getClaimsFromToken(token);
expirationDate = claims.getExpiration();
} catch (Exception e) {
expirationDate = null;
}
return expirationDate;
}
private boolean isTokenExpired(String token) {
final Date expirationDate = this.getExpirationDateFromToken(token);
return expirationDate.before(new Date(System.currentTimeMillis()));
}
public boolean validateToken(String token, UserDetails userDetails) {
final String username = getUsernameFromToken(token);
return username.equals(userDetails.getUsername()) && !isTokenExpired(token);
}
public String generateToken(UserDetails userDetails) {
Map<String, Object> claims = new HashMap<String, Object>();
claims.put("sub", userDetails.getUsername());
claims.put("created", new Date(System.currentTimeMillis()));
return Jwts.builder().setClaims(claims).setExpiration(new Date(System.currentTimeMillis() + expiration * 1000))
.signWith(SignatureAlgorithm.HS512, secret).compact();
}
}
SecurityConfiguration
package com.sbvtransport.sbvtransport.security;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
@SpringBootApplication
@Configuration
@EnableWebSecurity
@EnableAutoConfiguration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
authenticationManagerBuilder.userDetailsService(this.userDetailsService).passwordEncoder(passwordEncoder());
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Bean
public AuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
AuthenticationTokenFilter authenticationTokenFilter = new AuthenticationTokenFilter();
authenticationTokenFilter.setAuthenticationManager(authenticationManagerBean());
return authenticationTokenFilter;
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf().disable().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests().antMatchers("").permitAll();
httpSecurity.addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
}
}
It seems there is a problem with autowiring TokenUtils inside AuthenticationTokenFilter, but I also may be wrong.
I hope my question is clear enough, if I can do anything to improve it, please suggest it.
Error : Error message clearly says TokenUtils bean is not found
'com.sbvtransport.sbvtransport.security.TokenUtils' that could not be found.
You are missing @Component on TokenUtils, declaring class with @Component makes component scan to create singleton bean of this class in application context
@Component
public class TokenUtils {
And @Configuration on AuthenticationTokenFilter
@Configuration
public class AuthenticationTokenFilter extends UsernamePasswordAuthenticationFilter{
@SpringBootApplication enables component scan in the package it is declared
@EnableAutoConfiguration: enable Spring Boot’s auto-configuration mechanism
@ComponentScan: enable @Component scan on the package where the application is located (see the best practices)
@Configuration: allow to register extra beans in the context or import additional configuration classes
The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration, and @ComponentScan with their default attributes,
