如何将春豆注入休眠环境 RevisionListener

我正在使用Spring 5.1和Hibernate 5.3.9，包括hibernate-envers。我不知道如何将春豆注入休眠 envers 自定义修订侦听器。

我试过了

(@Service or @Component)
public class ExtendedRevisionListener implements RevisionListener {
@Autowired
private MyService myService;
void newRevision(Object revisionEntity){
myService.doSomething(...)
}
}

当然，该类包含在@ComponentScan包分辨率中。一个问题是 myService 没有注入到侦听器中。

在休眠-envers文档中：

https://docs.jboss.org/hibernate/orm/current/userguide/html_single/Hibernate_User_Guide.html#envers-basics

从Hibernate Envers 5.3开始，RevisionListener现在支持依赖注入。这个特性取决于各种依赖框架，如CDI和Spring，在Hibernate ORM引导期间提供必要的实现来支持注入。如果未提供限定实现，则将在不注入的情况下构造 RevisionListener。

不幸的是，我没有找到任何工作示例。

@Naros 我在春季持久性JPA中设置了EntityMaganerFactoryBean。配置 ->实体管理器 = new org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean((

在我的坚持JPAConfig中：

@EnableJpaRepositories(basePackages = "pl.atmoterm", entityManagerFactoryRef = "localContainerEntityManagerFactoryBean")
@Bean
@DependsOn({"dataSource"})
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(new String[]{
"pl.atmoterm.**.*"
});
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
em.setJpaProperties(additionalProperties());
return em;
}

使用 Spring Framework 5.1 和 Envers 设置 bean 注入实际上并不多。侦听器实现不需要由@Service或@Component注释，因为这些类实际上是由Hibernate构造的，然后ManagedBeanRegistry负责与用于注入/连接依赖项的任何DI框架进行协调。

如果您的MyService未注入到修订侦听器中，则有以下几点需要检查：

验证你使用的是Spring Framework 5.1或更高版本。
虽然其他 Spring 组件可能使用不同的版本方案，但重要的是要确保底层 Spring Framework 版本确实是 5.1+。
RevisionListener配置是否正确？
我通常通过添加一个带有@Entity注释的@RevisionEntity注释类来配置它，然后在@RevisionEntity注释的值属性中指定侦听器。如果您愿意，您应该能够使用org.hibernate.envers.revision_listener来指定侦听器类的完全限定类名，否则。
您的MyService可以注射到任何其他春豆中吗？
也许这里的问题是 Spring 一开始就没有构造你的MyServicebean，这会导致依赖注入在修订侦听器的 bean 注入期间不提供实现。

我在这里创建了一个小演示，您可以参考。我将考虑在本月晚些时候在Hibernate博客上发表一篇关于此的博客文章。

更新

只是简单地看一下 Spring 框架源代码，我相信问题是你正在手动创建一个LocalContainerEntityManagerFactoryBean，当注入 bean 工厂时，它实际上并没有为依赖注入创建必要的 Hibernate 配置。

我认为您可能需要自己手动设置：

@Bean
@DependsOn({"dataSource"})
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean(ConfigurableListableBeanFactory beanFactory) {
// Create the LocalContainerEntityManagerBean like you were
// Pass beanFactory here so right configuration gets applied
em.setJpaProperties(additionalProperties(beanFactory));
return em;
}
private Properties additionalProperties(ConfigurableListableBeanFactory beanFactory) {
// add your properties here like you were before
Properties properties = new Properties();
// THIS HERE IS THE CRITICAL SETTING
properties.put(
"hibernate.resource.beans.container", 
new SpringBeanContainer(beanFactory));
return properties
}

虽然LocalContainerEntityManagerFactoryBean是BeanFactoryAware，但它只是设置一个内部属性，仅此而已。该属性实际上并未设置为Hibernate检测它所需的配置属性，因此Hibernate最终默认为CDI注入，因为您处于CDI环境中。

在上面，由于正在构建 EntityManagerFactory bean，我们在BeanFactory实例中具有配置传递。我们将该工厂传递到additionalProperties，在那里我们手动将其应用于正确的Hibernate配置，然后将其传递给Hibernate引导程序。

如果您使用的是 Spring Boot，最好使用 ApplicationContextAware：

public class MyRevisionListener implements RevisionListener, ApplicationContextAware {
private MyService myService;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.myService = applicationContext.getBean(MyService.class);
}
@Override
public void newRevision(Object revisionEntity) {
MyRevisionEntity revinfo = (MyRevisionEntity) revisionEntity;
// Use myService here to set something on MyRevisionEntity
}
}

这是使用 Spring Boot 2.3.9 测试的。

有其他方法...你可以使用 Spring 中的静态类。

检查。。。。

import org.hibernate.envers.RevisionListener;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;

public class EnverRevisionListener implements RevisionListener{
@Override
public void newRevision(Object revisionEntity) {
EnverRevisionEntity revEntity = (EnverRevisionEntity) revisionEntity;
SecurityContext context = SecurityContextHolder.getContext();
Authentication auth = context.getAuthentication();
revEntity.setUserName(auth.getName());
}
}

我正在使用带有 Hibernate 6.2 的 Spring Boot 3.1.1，但这两个答案都不适合我。相反，我可以通过以下方式解决它：

应用程序.yml

spring.jpa.properties:
hibernate:
# see https://github.com/hibernate/hibernate-orm/blob/6.2/migration-guide.adoc#cdi
cdi.extensions: false

修订侦听器

public class MyRevisionListener implements RevisionListenere {
private final MyService myService;
public MyRevisionListener (@org.springframework.context.annotation.Lazy MyService myService) {
this.myService = myService;
}
@Override
public void newRevision(Object revisionEntity) {
MyRevisionEntity revinfo = (MyRevisionEntity) revisionEntity;
// Use myService here to set something on MyRevisionEntity
}
}
