Dont erstellen UserRepository Bohne

Question

Im beginer im Frühjahr, Hilfe

@Entity 
@Table(name="users") 
public class User { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private long id; 
    private String username; 
    private String password; 

    @ManyToMany 
    @JoinTable(name = "users_roles", 
      joinColumns = {@JoinColumn(name = "user_id")}, 
      inverseJoinColumns = @JoinColumn(name = "role_id")) 
    private Set<Role> roles; 

    public Set<Role> getRoles() { 
     return roles; 
    } 

    public void setRoles(Set<Role> roles) { 
     this.roles = roles; 
    } 

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

    public long getId() { 
     return id; 
    } 

    public void setId(long id) { 
     this.id = id; 
    } 

    public String getUsername() { 
     return username; 
    } 

    public void setUsername(String username) { 
     this.username = username; 
    } 

    protected User(){} 
    public User(String name, String pass) { 
     username = name; 
     password = pass; 
    } 

} 

Repository

Entity bitte:

public interface UserRepository extends JpaRepository<User, Long> { 
    User findByUsername(String username); 
} 

Controller:

@RestController 
    @RequestMapping("/users") 
    @PreAuthorize("hasRole('ADMIN')") 
    public class UserController { 
     @Autowired 
     UserRepository userRepository; 

     @RequestMapping(method = RequestMethod.GET) 
     public List<User> getUsers() 
     { 
      List<User> result = new ArrayList<User>(); 
      userRepository.findAll().forEach(result::add); 
      return result; 
     } 

     @RequestMapping(method = RequestMethod.POST) 
     public User addUser(String username, String password, String password_confirm) 
     { 
      if (username.isEmpty() || password.isEmpty() || password_confirm.isEmpty()) 
       return null; 
      if (!password.equals(password_confirm)) 
       return null; 
      return userRepository.save(new User(username, password)); 
     } 

     @RequestMapping(value = "/add",method = RequestMethod.GET) 
     public ModelAndView getUserForm() 
     { 
      return new ModelAndView("add"); 
     } 

     @RequestMapping(value = "/{id}", method = RequestMethod.DELETE) 
     public void delete(@PathVariable("id") Long id) 
     { 
      userRepository.delete(id); 
     } 

     @RequestMapping(value = "/{id}", method = RequestMethod.GET) 
     public User getUser(@PathVariable("id") Long id) 
     { 
      return userRepository.findOne(id); 
     } 
    } 

Daten Config:

@Configuration 
@EnableTransactionManagement 
@PropertySource(value = {"classpath:hibernate.properties"}) 
@EnableJpaRepositories("com.sergey.repository") 
public class DataConfig { 
    @Autowired 
    private Environment environment; 

    @Bean 
    public DataSource dataSource() { 
     DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
     dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName")); 
     dataSource.setUrl(environment.getRequiredProperty("jdbc.url")); 


    dataSource.setUsername(environment.getRequiredProperty("jdbc.username")); 
      dataSource.setPassword(environment.getRequiredProperty("jdbc.password")); 
      return dataSource; 
     } 

    @Bean 
    public LocalSessionFactoryBean sessionFactory() { 
     LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
     sessionFactory.setDataSource(dataSource()); 
     sessionFactory.setPackagesToScan("com.sergey.entity"); 
     sessionFactory.setHibernateProperties(hibernateProperties()); 

     return sessionFactory; 
    } 

    private Properties hibernateProperties() { 
     Properties properties = new Properties(); 
     properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect")); 
     properties.put("show_sql", environment.getRequiredProperty("hibernate.show_sql")); 
     properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto")); 
     return properties; 
    } 

    @Bean 
    @Autowired 
    public HibernateTransactionManager transactionManager(SessionFactory s) { 
     HibernateTransactionManager txManager = new HibernateTransactionManager(); 
     txManager.setSessionFactory(s); 
     return txManager; 
    } 

    @Bean 
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() { 
     return new PersistenceExceptionTranslationPostProcessor(); 
    } 


    @Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
     LocalContainerEntityManagerFactoryBean emfb = new LocalContainerEntityManagerFactoryBean(); 
     emfb.setDataSource(dataSource()); 
     emfb.setPackagesToScan("com.sergey.entity"); 
     emfb.setJpaVendorAdapter(jpaVendorAdapter()); 
     emfb.setJpaProperties(hibernateProperties()); 
     return emfb; 
    } 

    @Bean 
    public JpaVendorAdapter jpaVendorAdapter() { 
     return new HibernateJpaVendorAdapter(); 
    } 

    @Bean 
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) { 
     JpaTransactionManager transactionManager = new JpaTransactionManager(); 
     transactionManager.setEntityManagerFactory(emf); 
     return transactionManager; 
    } 

}

Answer 1

Frühling Repositorys zur Laufzeit durch Rahmen Frühlings-PPV umgesetzt und @NoRepositoryBean sollten nur für die BaseRepositories gekennzeichnet sein, die verwendet werden, Bereitstellen eines Standardverhaltens für alle Unterschnittstellen (falls vorhanden).

Die Ausnahme, sagt, dass „Keine Warte Bean vom Typ [com.sergey.repository.UserRepository]“ für die Abhängigkeit gefunden, ist dies, weil Frühling Behälter nicht die Umsetzung vorsah, wie es mit @NoRepositoryBean

Mit anderen Worten markiert, Sie @NoRepositoryBean Anmerkung nicht hinzufügen sollten zu der UserRepository, da es eine konkrete Repository-Schnittstelle ist, die von Spring-JPA-Framework (zur Laufzeit) implementiert werden muss. So entfernen Sie die Annotation an der Spitze und dann UserRepository Klasse wird wie folgt dar:

public interface UserRepository extends JpaRepository<User, Long> { 
    User findByUsername(String username); 
} 

Bitte beachten Sie die unten Dokumentation für weitere Details:
