UnsatisfiedDependencyException - Error creating bean with name

Question

when I try to run test cases I keep running to this issue. Can't figure out what is going on. Any help, please? Thank you.

This is my config file, Seems like error happening here bases on stacktrace.

@Configuration
@EnableWebSecurity
public class WebSecurityConfig  extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtTokenProvider jwtTokenProvider;

    @Autowired
    private UserDetailsService userDetailsService;

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()
                .authorizeRequests()
                .antMatchers("/auth/**").permitAll()
                .anyRequest().fullyAuthenticated()
                .and()
                .logout().permitAll()
                .logoutRequestMatcher(new AntPathRequestMatcher("/api/user/logout", "POST"))
                .and()
                .formLogin().loginPage("/auth/login").and()
                .httpBasic().and()
                .csrf().disable();

        //jwt filter
        http.addFilter(new JWTAuthorizationFilter(authenticationManager(),jwtTokenProvider));
    }



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

    //Cross origin resource sharing.
    @Bean
    public WebMvcConfigurer corsConfigurer(){
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("*").allowedMethods("*");
            }
        };
    }
}

And acutal JWTProvider file

 @Component
public class JwtTokenProvider {

    @Value("${app.jwt.secret}")
    private String jwtSecret;

    @Value("${app.jwt.token.prefix}")
    private String jwtTokenPrefix;

    @Value("${app.jwt.header.string}")
    private String jwtHeaderString;

    @Value("${app.jwt.expiration-in-ms}")
    private Long jwtExpirationInMs;

    public String generateToken(Authentication auth) {
        String authorities = auth.getAuthorities().stream().map(GrantedAuthority::getAuthority)
                .collect(Collectors.joining());

        return Jwts.builder().setSubject(auth.getName()).claim("roles", authorities)
                .setExpiration(new Date(System.currentTimeMillis() + jwtExpirationInMs))
                .signWith(SignatureAlgorithm.HS512, jwtSecret).compact();
    }

    public Authentication getAuthentication(HttpServletRequest request) {
        String token = resolveToken(request);
        if (token == null) {
            return null;
        }
        Claims claims = Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(token).getBody();
        String username = claims.getSubject();
        final List<GrantedAuthority> authorities = Arrays.stream(claims.get("roles").toString().split(","))
                .map(role -> role.startsWith("ROLE_") ? role : "ROLE_" + role).map(SimpleGrantedAuthority::new)
                .collect(Collectors.toList());
        return username != null ? new UsernamePasswordAuthenticationToken(username, null, authorities) : null;
    }

    public boolean validateToken(HttpServletRequest request) {
        String token = resolveToken(request);
        if (token == null) {
            return false;
        }
        Claims claims = Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(token).getBody();
        if (claims.getExpiration().before(new Date())) {
            return false;
        }
        return true;
    }

    private String resolveToken(HttpServletRequest req) {
        // Bearer key...
        String bearerToken = req.getHeader(jwtHeaderString);
        if (bearerToken != null && bearerToken.startsWith(jwtTokenPrefix)) {
            return bearerToken.substring(7, bearerToken.length());
        }
        return null;
    }
}

Honestly I dont understand exactly what Spring is complatining about. Been looking debuging it for past 4 hours, still nothing. (

Answer 1

One possible reason is that Spring is not picking it up in its default component scan. By default, Spring will only for package under the top SpringApplication class with the main method.

So if you SpringApplication is located: my.app.pkg.SpringApplication.java

Other classes in my.app.pkg will not automatically autowire. You can move then to a package below: my.app.pkg.abc

You can also use the @ComponentScan(...) annotation and list all the packages with spring components.
