我正在集成Spring4和Hibernate5，但有一个问题我无法解决。我在BaseEntity类上使用@EntityListener注释，它是其他业务模型的超级类。我也在BaseEntity上使用@MappdSuperclass。但它不起作用！

使用Spring base注解并成功运行应用程序。我还向db插入了一条记录。所以我认为我的项目配置是最新的。

有人告诉我为什么吗？非常感谢。

这是BaseEntity类。

@MappedSuperclass
@EntityListeners(EntityListener.class)
public class BaseEntity implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(nullable = false, updatable = false)
    private Date createDate;

    @Column(nullable = false)
    private Date modifyDate;

    public Long getId() {
        return id;
    }

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

    public Date getCreateDate() {
        return createDate;
    }

    public void setCreateDate(Date createDate) {
        this.createDate = createDate;
    }

    public Date getModifyDate() {
        return modifyDate;
    }

    public void setModifyDate(Date modifyDate) {
        this.modifyDate = modifyDate;
    }
}

这是EntityListener类。

public class EntityListener {

  @PrePersist
  public void prePersist(BaseEntity entity) {
    entity.setCreateDate(new Date());
    entity.setModifyDate(new Date());
  }

  @PreUpdate
  public void preUpdate(BaseEntity entity) {
    entity.setModifyDate(new Date());
  }

}

以下是我基于Spring注解的项目配置。

@Configuration
@EnableWebMvc
//@ImportResource({ "classpath:xxxxx.xml" })
@PropertySources({
    @PropertySource("classpath:application.properties")
})
@ComponentScan({"com.yeager.admin.persistence","com.yeager.admin.web","com.yeager.admin.service","com.yeager.admin.common"})
@EnableAspectJAutoProxy
//@EnableRetry
public class AppConfig {

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver getResolver() throws IOException {
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        return resolver;
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean
    public static SpringContext springContext() {
        return new SpringContext();
    }

}

像这样DAL的主要配置，

@Configuration
@EnableTransactionManagement
@PropertySource({"classpath:persistence-mysql.properties"})
public class PersistenceConfig {

    @Autowired
    private Environment env;

    public PersistenceConfig() {
        super();
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {

        final LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan("com.yeager.admin.persistence.entity");
        sessionFactory.setHibernateProperties(hibernateProperties());


        return sessionFactory;
    }

    @Bean
    public DataSource dataSource() {
        ComboPooledDataSource comboPooledDataSource = new ComboPooledDataSource();
        try {
            comboPooledDataSource.setDriverClass(env.getProperty("jdbc.driver"));
        } catch (PropertyVetoException e) {
            e.printStackTrace();
        }
        comboPooledDataSource.setJdbcUrl(env.getProperty("jdbc.url"));
        comboPooledDataSource.setUser(env.getProperty("jdbc.username"));
        comboPooledDataSource.setPassword(env.getProperty("jdbc.password"));
        comboPooledDataSource.setInitialPoolSize(Integer.valueOf(env.getProperty("datasource.pool.initialPoolSize")));

        return comboPooledDataSource;
    }

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

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

    private final Properties hibernateProperties() {

        final Properties hibernateProperties = new Properties();

        hibernateProperties.setProperty("hibernate.dialect", env.getProperty("hibernate.dialect"));
        hibernateProperties.setProperty("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
        hibernateProperties.setProperty("hibernate.generate_statistics",env.getProperty("hibernate.generate_statistics"));
        hibernateProperties.setProperty("hibernate.jdbc.fetch_size", env.getProperty("hibernate.jdbc.fetch_size"));
        hibernateProperties.setProperty("hibernate.jdbc.batch_size", env.getProperty("hibernate.jdbc.batch_size"));
        hibernateProperties.setProperty("hibernate.max_fetch_depth", env.getProperty("hibernate.max_fetch_depth"));
        hibernateProperties.setProperty("hibernate.cache.use_second_level_cache",env.getProperty("hibernate.cache.use_second_level_cache"));
        hibernateProperties.setProperty("hibernate.cache.use_query_cache",env.getProperty("hibernate.cache.use_query_cache"));
//      hibernateProperties.setProperty("hibernate.cache.provider_class",env.getProperty("hibernate.cache.provider_class"));
        hibernateProperties.setProperty("hibernate.hbm2ddl.auto", "update");

        return hibernateProperties;
    }

}

我使用Hibernate的LocalSessionFactoryBean类而不是JPA的EntityManager类。我想知道这是不是原因？

我错了。我不应该在Spring LocalSessionFactoryBean类上使用@EntityListener注解。对于hibernate5，有一种特殊的配置方式。http://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/Hibernate_User_Guide.html#annotations-jpa-entitylisteners现在，我修改我的代码如下，

@Component
public class EntityEventListener {

    @Autowired
    private SessionFactory sessionFactory;

    @PostConstruct
    public void registerListeners(){
        EventListenerRegistry eventListenerRegistry = ((SessionFactoryImplementor) sessionFactory).getServiceRegistry().getService(EventListenerRegistry.class);
        eventListenerRegistry.prependListeners(EventType.PRE_INSERT, PreInsertEntityListener.class);
    }

}

预插入实体监听器

public class PreInsertEntityListener implements PreInsertEventListener {
    @Override
    public boolean onPreInsert(PreInsertEvent event) {
//        if (event.getEntity() instanceof AdminUser){
//            ((AdminUser) event.getEntity()).setCreateDate(new Date());
//            ((AdminUser) event.getEntity()).setModifyDate(new Date());
//        }
        BaseEntity baseEntity = (BaseEntity) event.getEntity();
        baseEntity.setCreateDate(new Date());
        baseEntity.setModifyDate(new Date());
        return false;
    }
}

但是，我还有另一个问题。我阅读hibernate文档并搜索有关此的许多信息。当我插入实体数据时，我的代码已经不起作用了。

请帮帮我，谢谢！
