Migration von Migrate to Spring MVC 4 + Hibernate5

Question

Ich bin eine Anwendung von Jersey Migration 1.18, Frühling 3, Hibernate 3.6, Maven zu einer völlig neuen Architektur: Frühling 4.3 (via Frühling Boot), Hibernate 5 und Gradel.

Während der „Portierung“ des Frühlings application.xml auf eine Codebasiskonfiguration, ich die folgende Ausnahme gegenüber:

Fehler Bean mit dem Namen ‚jpaContext‘ zu erstellen: Unbefriedigend Abhängigkeit. .. Keine Warte Bohne für Abhängigkeits [java.util.Set] gefunden

Hier ist die lange stacktrace

Description: 

Parameter 0 of constructor in org.springframework.data.jpa.repository.support.DefaultJpaContext required a bean of type 'java.util.Set' that could not be found. 


Action: 

Consider defining a bean of type 'java.util.Set' in your configuration. 

Tatsache ist, dass ich nicht die DefaultJpaContext in meinem Code definiert haben:

@Configuration 
@EnableTransactionManagement 
@EnableAspectJAutoProxy(proxyTargetClass = true) 
public class DatabaseConfig { 

    @Autowired private Environment env; 
    @Autowired private DataSource dataSource; 
    @Autowired private SessionFactory sessionFactory; 

    private static final String DB_DRIVER_CLASS_NAME = "com.mysql.jdbc.Driver"; 
    private static final String HIBERNATE_DIALECT = "org.hibernate.dialect.MySQL5Dialect"; 
    private static final String HIBERNATE_VALIDATION = "validate"; 
    private static final String SHOW_SQL    = "false"; 
    private static final String ENTITY_PACKAGE  = MainEntity.class.getPackage().getName(); 

    final Logger log = LoggerFactory.getLogger(DatabaseConfig.class); 


    @Bean 
    public DataSource dataSource() { 
     final String driverName = env.getProperty("db.driver", DB_DRIVER_CLASS_NAME); 
     final String url  = env.getProperty("db.url"); 
     final String username = env.getProperty("db.username"); 
     final String password = env.getProperty("db.password"); 
     final DriverManagerDataSource dataSource = new DriverManagerDataSource(); 

     if (log.isInfoEnabled()) { 
      log.info("Database Configuration:"); 
      log.info("Setting driverName to {}", driverName); 
      log.info("Setting url to {}", url); 
      log.info("Setting username to {}", username); 
      if (StringUtils.isEmpty(password)) log.warn("Password not specified"); 
      else log.info("Setting password"); 
     } 

     dataSource.setDriverClassName(driverName); 
     dataSource.setUrl(url); 
     dataSource.setUsername(username); 
     dataSource.setPassword(password); 
     return dataSource; 
    } 

    @Bean 
    public LocalSessionFactoryBean sessionFactory(){ 
     LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
     sessionFactory.setDataSource(dataSource); 
     sessionFactory.setPackagesToScan(new String[] {ENTITY_PACKAGE}); 

     // Hibernate properties 
     Properties additionalProperties = new Properties(); 
     additionalProperties.put("hibernate.dialect"  , env.getProperty("db.dialect" , HIBERNATE_DIALECT)); 
     additionalProperties.put("hibernate.hbm2ddl.auto", env.getProperty("db.validation", HIBERNATE_VALIDATION)); 
     additionalProperties.put("hibernate.show_sql" , env.getProperty("db.sql.show" , SHOW_SQL)); 

     sessionFactory.setHibernateProperties(additionalProperties); 
     return sessionFactory; 
    } 

    @Bean 
    public HibernateTransactionManager transactionManager(){ 
     HibernateTransactionManager transactionManager = new HibernateTransactionManager(); 
     transactionManager.setSessionFactory(sessionFactory); 
     return transactionManager; 
    } 
} 

aktualisieren

Hier ist es ein Stück gradle Build ist:

compile('org.springframework.boot:spring-boot-starter-data-jpa') 
// ... 
compile('org.springframework.boot:spring-boot-starter-security') 
compile('org.springframework.boot:spring-boot-starter-web') 
compile group: 'org.hibernate'  , name: 'hibernate-core'  , version: '5.2.8.Final' 
// ... 

Was ich fehlt?

Danke, Davide.

Answer 1

Basierend auf der Spring-Boot-Fehlermeldung kann die DefaultJpaContext-Bean nicht erstellt werden, deren Konstruktor Set<javax.persistence.EntityManager> entityManagers erfordert.

Sieht aus wie Sie Spring-Data Abhängigkeit in Ihrem pom.xml (oder build.gradle) haben, die die JPA erfordert EntityManagerFactory, während Sie Hibernate (LocalSessionFactoryBean) Sachen haben. Müssen Sie DefaultJpaContext Bohnen haben?
