Spring boot security无法自动连接@Repository

当我在spring boot中添加安全配置时，我遇到了一个恼人的错误：

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 这是spring引导安全性的配置：

这是一个似乎无法通过Spring boot自动连接的用户存储库：

@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);
}

我通过自动连接到SecurityConfig中来解决这个问题。我使用了所有的服务和存储库。

您的

UserDetailsServiceImpl

看起来怎么样？它是否实现了

org.springframework.security.core.userdetails.userdetails服务

？发布完整的堆栈跟踪。

@SpringBootApplication

？在此处添加您的userdetails服务实现

@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());
    }
}

@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);
}
