Spring Data JPA中的模式自动更新（Foriegn Keys的添加）

Question

我正在使用spring数据jpa。我使用两个数据源，所以我配置了自己的数据源，他们正在工作。但是当我使用两个数据源时，spring boot会自动为我的表创建foriegn键。但是当我禁用了手动配置＆amp;使用默认数据源，那么它不会发生？如何更改代码。

这是我的配置类

主要

@Configuration
@EnableJpaRepositories(basePackages="com.example.repository",
entityManagerFactoryRef = "primaryEntityManagerFactory")
public class DataSourceConfiguration {

    @Bean(name="primaryDataSource")
    @Primary
    @ConfigurationProperties(prefix = "datasource.primary")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    @Primary
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager tm = new JpaTransactionManager();
        tm.setEntityManagerFactory(primaryEntityManagerFactory().getObject());
        return tm;
    }

    @Bean(name="primaryEntityManagerFactory")
    @Primary
    LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory() {

        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        factoryBean.setDataSource(primaryDataSource());
        factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        factoryBean.setPackagesToScan(DataSourceConfiguration.class.getPackage().getName());

        return factoryBean;
    }

}

中

@Configuration
@EnableJpaRepositories(basePackages="com.example.repository1",
entityManagerFactoryRef = "secondaryEntityManagerFactory")
public class DS2Configuration {

    @Bean(name="secondaryDataSource")
    @ConfigurationProperties(prefix = "datasource.secondary")
    public DataSource secondaryDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager tm = new JpaTransactionManager();
        tm.setEntityManagerFactory(secondaryEntityManagerFactory().getObject());
        return tm;
    }

    @Bean(name="secondaryEntityManagerFactory")
    LocalContainerEntityManagerFactoryBean secondaryEntityManagerFactory() {

        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        factoryBean.setDataSource(secondaryDataSource());
        factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        factoryBean.setPackagesToScan(DataSourceConfiguration.class.getPackage().getName());

        return factoryBean;
    }

}

如何更改这些以禁用自动外围密钥创建？
