Spring boot security cannot autowired a #Repository - spring

Question

When i added security configuration to spring boot, i came into this annoying error:
2017-05-18 15:23:29.160 WARN 1806 --- [ main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through field 'userDetailsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userDetailsServiceImpl': Unsatisfied dependency expressed through field 'userRepo'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Cannot create inner bean '(inner bean)#236c098' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#236c098': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory': Post-processing of FactoryBean's singleton object failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'chatController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userRepo'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': FactoryBean threw exception on object creation; nested exception is java.lang.NullPointerException
this is the springBootApplication:
public class Ailab4finalApplication {
public static void main(String[] args) {
SpringApplication.run(Ailab4finalApplication.class, args);
}
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("validation");
return messageSource;
}
}
this is the configuration of spring boot security:
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Autowired
private Environment env;
#Bean(name="passwordEncoder")
public PasswordEncoder getPasswordEncoder() {
return new BCryptPasswordEncoder();
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/webjars/**", "/css/**", "/registration", "/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
http.csrf().disable();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(getPasswordEncoder());
}
}
and this the userRepository that seems cannot be autowired by Spring boot:
#Repository
public interface UserRepository extends CrudRepository<UserHibernate, Long> {
#Query("select u from UserHibernate u where u.email = ?1")
public UserHibernate findByEmail(String email);
#Query("select u from UserHibernate u where u.nickname = ?1")
public UserHibernate findByNickname(String nickname);
#Query("select u from UserHibernate u where u.id = ?1")
public UserHibernate findById(Long id);
}
and finally, this is my project tree:
src:
-Ailab4finalApplication.java
-DatabaseConfig.java
-SecurityConfig.java
src/services:
-SecurityService.java
-SecurityServiceImpl.java
-UserDetailsServiceImpl.java
-UserService.java
-UserServiceImpl.java
src/jpa_repositories:
-SecurityService.java
-SecurityServiceImpl.java
-UserDetailsServiceImpl.java
-UserService.java
-UserServiceImpl.java

Answer 1

I resolve the problem by Autowiring into Securityconfing all the services and repositories that i used.
