将openjpa配置为spring boot

Question

我试图在Spring启动时将Hibernate的默认JPA实现更改为OpenJPA。我在谷歌搜索但没有太多关于如何配置openJPA到Spring启动。任何意见将是有益的。感谢

@Configuration
public class OpenJPAConfig extends JpaBaseConfiguration {
    protected OpenJPAConfig(DataSource dataSource, JpaProperties properties,
                            ObjectProvider<JtaTransactionManager> jtaTransactionManager,
                            ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers) {
        super(dataSource, properties, jtaTransactionManager, transactionManagerCustomizers);
    }

    @Override
    protected AbstractJpaVendorAdapter createJpaVendorAdapter() {
        return new OpenJpaVendorAdapter();
    }
    @Override
    protected Map<String, Object> getVendorProperties() {
        return new HashMap<>(0);
    }
}
