如何在HibernateJpaAutoConfiguration中指定packagesToScan？
如何在HibernateJpaAutoConfiguration中指定packagesToScan？
提问于 2014-08-18 23:10:19
我在Spring单元测试中直接使用了HibernateJpaAutoConfiguration。在配置Hibernate和EntityManager时，不会扫描任何实体。
异常

final LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setPersistenceUnitName("buzzPU"); // persistence.xml
factoryBean.setDataSource(dataSource);
factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
factoryBean.setPersistenceXmlLocation("classpath*:META-INF/donotparsepersistence.xml");
factoryBean.setPackagesToScan("org.soluvas.buzz.core.jpa");请注意，我没有使用META-INF/persistence.xml

来自Spring Boot参考...
Spring Boot尝试根据它找到的@EnableAutoConfiguration来猜测@Entity定义的位置。为了获得更多的控制，你可以使用@EntityScan注解，例如
@Configuration
@EnableAutoConfiguration
@EntityScan(basePackageClasses=City.class)
public class Application {
//...

使用以下命令也会有所帮助：
@EntityScan("org.soluvas.buzz.core.jpa")它是“basePackages”属性的别名，用于配置要扫描带注释的实体的包列表。
此注释提供了手动设置LocalContainerEntityManagerFactoryBean.setPackagesToScan(String...)的另一种方法
如果您希望以类型安全的方式配置实体扫描，或者如果您的LocalContainerEntityManagerFactoryBean是auto-configured.
，则它特别有用
