Question

我有一个简单的用例，仅涉及杂项操作，而且我认为它不需要支持事务。从stacktrace看来，它是强制性的。

@Configuration
@ComponentScan("com.cap")
@EnableJpaRepositories
public class MyConfig{

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean em
            = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan(new String[] { "com.cap" });

    JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    em.setJpaProperties(additionalProperties());

    return em;
}

@Bean
public DataSource dataSource(){
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
    dataSource.setUrl("jdbc:mysql://localhost:3306/sakila?useSSL=false");
    dataSource.setUsername( "root" );
    dataSource.setPassword( "root");
    return dataSource;
}

我可以在没有事务管理器的情况下将spring jpa休眠吗？
