带有嵌入式 Derby 的 Spring : hibernate dialect deprecation

Question

我有一个使用 Spring Boot 和配置注释配置的 Spring 应用程序。

JPA 配置为:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories
public class JpaConfiguration {

    @Bean
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.DERBY).build();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource,
            JpaVendorAdapter jpaVendorAdapter) {
        LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
        lef.setDataSource(dataSource);
        lef.setJpaVendorAdapter(jpaVendorAdapter);
        lef.setPackagesToScan( /* "..." */ );
        return lef;
    }

    @Bean
    public JpaVendorAdapter jpaVendorAdapter() {
        HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
        hibernateJpaVendorAdapter.setShowSql(true);
        hibernateJpaVendorAdapter.setGenerateDdl(true);
        hibernateJpaVendorAdapter.setDatabase(Database.DERBY);
        return hibernateJpaVendorAdapter;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        return new JpaTransactionManager();
    }
}

我一直在日志中:

[...]
HHH000400: Using dialect: org.hibernate.dialect.DerbyDialect
HHH000430: The DerbyDialect dialect has been deprecated; use one of the version-specific dialects instead
[...]

我尝试添加:

@Bean
public DerbyTenSevenDialect jpaDialect() {
    return new DerbyTenSevenDialect();
}

但是返回的 bean 与以下内容不兼容:

LocalContainerEntityManagerFactoryBean lef //.....
lef.setJpaDialect(JpaDialect);

如何消除弃用警告？

Answer 1

只需完全放弃以下行(无需用其他任何内容替换):

hibernateJpaVendorAdapter.setDatabase(Database.DERBY);

这就是我所做的一切，Hibernate 已正确记录:

Using dialect: org.hibernate.dialect.DerbyTenSevenDialect

之后就不需要手动定义方言Bean了。 Hibernate 自己找出正确的方言
