Question

我正在使用带有Service Pack 1和Forms Package的Adobe Experience Manager（AEM）6.4。我有很多扩展的属性/属性，因此我制作了数据库图。我不想将所有其他内容保存在crx中，而是想将其保存在Oracle数据库中。

数据库图很复杂，所以我至少要使用JPA（休眠）。如果Spring可以使它更易于使用，那对我来说就没事了。

我了解到很多OSGI正在使用蓝图而不是Spring，但是您可以将其结合使用。

我真的在寻找一个很好的示例，说明如何使JPA和Oracle数据库工作。

Adobe根本没有帮助，他们无法显示如何使用AEM和JPA / Hibernate / Spring / blueprint的示例。

有人可以帮我使事情正常吗？使用AEM和JPA？

我认为我需要的是：

persistence.xml（RESOURCE_LOCAL还是JTA？）
带有注释@Entity和其他JPA注释的实体类
带有事务控制的服务类，也许还有管理器类，可以提交以与实体类一起工作并从查询中获取结果，也许我可以将其全部放入服务类中
hibernate-osgi（依赖项）
用于连接（依赖项）的ojdbc7
org.apache.aries.jpa.api（依赖项）

但是我该如何使事情发生呢？什么都没有。我什至不知道这是正确的方法。

我应该使用蓝图或Spring还是两者一起使用？

我从Apache找到了这个白羊座的东西。 http://aries.apache.org 并穿了一些我不太了解它们如何工作的样品。 https://github.com/apache/aries-jpa/tree/master/examples

还有一些OSGI示例，对于我的情况，它们看起来非常不完整。 https://enroute.osgi.org/tutorial/032-tutorial_microservice-jpa.html

那么有人在AEM和JPA方面有一定经验吗？

Answer 1

我找到了解决方案，并在网站上的此处发布了帖子。

https://forums.adobe.com/message/10640295#10640295

我觉得我是将AEM与JPA / Hibernate相结合的第一人。现在，我可以检查使用spring和使用Transactions进行操作是否有好处。

那两个否决了这个问题的人，我确定你是adobe的人->谢谢，现在我在你自己的cms上比你更熟练，因为在我发帖之前没有解决这个问题的方法。 / p>

更新：Maven依赖关系。如果您对依赖项有疑问，则必须将其嵌入并添加属性“ Embed-Transitive to true”

 <plugin>

                </instructions>
            </configuration>
        </plugin>

Answer 2

让我描述一下如何在我们的项目中实现它。我们将AEM 6.3与SP2一起使用。我们在根pom.xml中有下一个依赖项：

    <!-- JPA -->
    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.1-api</artifactId>
        <version>1.0.0.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>

    <!-- /JPA-->

然后，我们有了提供JPA依赖项和OSGI服务的捆绑包，该服务允许获取休眠会话。捆绑包pom.xml

</project>

在捆绑包中，我们有下一项服务：

package com.myproject.db;

import org.hibernate.Session;

public interface JPASessionFactory {
    Session openSession();

    void closeSession(Session session);
}

实现：

package com.myproject.db.impl;

import com.myproject.db.JPASessionFactory;
import org.apache.felix.scr.annotations.*;
import org.apache.sling.commons.osgi.PropertiesUtil;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.cfg.Environment;

import javax.sql.DataSource;
import java.util.Map;

@Service
@Component(metatype = true, policy = ConfigurationPolicy.REQUIRE)
@Properties({
        @Property(label = "Hibernate SQL dialect", name = Environment.DIALECT),
        @Property(label = "Show SQL", name = Environment.SHOW_SQL, boolValue = false),
        @Property(label = "Bulk ID Strategy", name = Environment.HQL_BULK_ID_STRATEGY)
})
public class JPASessionFactoryImpl implements JPASessionFactory {

    @Reference(target = "(datasource.name=myproject)")
    private DataSource dataSource;

    private SessionFactory sessionFactory;

    @Activate
    protected void activate(Map<String, Object> properties) {
        StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                .configure()
                .applySetting(Environment.DIALECT, PropertiesUtil.toString(properties.get(Environment.DIALECT), ""))
                .applySetting(Environment.SHOW_SQL, PropertiesUtil.toBoolean(properties.get(Environment.SHOW_SQL), false))
                .applySetting(Environment.DATASOURCE, dataSource);

        String bulkIdStrategy = PropertiesUtil.toString(properties.get(Environment.HQL_BULK_ID_STRATEGY), "");
        if (!bulkIdStrategy.isEmpty()) {
            builder.applySetting(Environment.HQL_BULK_ID_STRATEGY, bulkIdStrategy);
        }
        sessionFactory = new Configuration().buildSessionFactory(builder.build());
    }

    @Deactivate
    protected void deactivate() {
        if (sessionFactory != null) {
            sessionFactory.close();
        }
    }

    @Override
    public Session openSession() {
        return sessionFactory.openSession();
    }

    @Override
    public void closeSession(Session session) {
        if (session != null && session.isOpen()) {
            session.close();
        }
    }
}

该服务的osgi配置：

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
          jcr:primaryType="sling:OsgiConfig"
          hibernate.dialect="org.hibernate.dialect.H2Dialect"
          hibernate.show_sql="{Boolean}true"/>

DataSourceFactory apps / myproject-forms / configuration / config.local / org.apache.sling.datasource.DataSourceFactory-localh2.xml的配置：

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
          jcr:primaryType="sling:OsgiConfig"
          datasource.name="myproject"
          driverClassName="org.h2.Driver"
          url="jdbc:h2:./myprojectlocal;AUTO_SERVER=TRUE"
          username="sa"
          password=""
          testOnBorrow="{Boolean}true"
          testOnReturn="{Boolean}true"
          testWhileIdle="{Boolean}true"
          validationQuery="SELECT 1"/>

我们还在捆绑软件的“ resources”文件夹中有一个Hibernate配置文件hibernate.cfg.xml。

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

  <session-factory>
    <property name="hbm2ddl.auto">update</property>
    <property name="current_session_context_class">thread</property>
    <mapping class="com.myproject.db.Entity1"/>
    <mapping class="com.myproject.db.Entity2"/>
  </session-factory>
</hibernate-configuration>

Answer 3

有些博客文章描述了如何在AEM / CQ中实现JPA持久性。在using-jpa-to-write-database-applications-in-an-osgi-container-e-g-felix-or-adobe-aem-cq5中，他们描述了如何使用PersistenceUnit设置JNDI数据源以及如何@Reference EntityManagerFactory。

Answer 4

我们已使用以下两种方法将Hibernate 5.4.5和JPA 2.2集成到Adobe Experience Manager 6.4.4中。请检查https://soft-werke.com/en/archives/news-en/how-to-install-hibernate-5-4-5-jpa-2-2-in-adobe-experience-manager-6-4-4/了解更多详细信息。

经典方法-使用content-package-maven-plugin在AEM软件包管理器中安装具有所有嵌入式Hibernate依赖关系的zip软件包。下面是一个Maven配置文件的示例，以后可以将其排除在外，以避免在每个AEM部署中安装Hibernate。

使用Maven Invoker API安装Hibernate软件包的Java代码：

public class HibernateInstaller {
    public static void main(String[] args) throws Exception {
        String bundleFolder,
               xmlFilePath,
               slingUser,
               slingPassword,
               url;
        if (args != null && args.length == 5) {
            bundleFolder = args[0];
            xmlFilePath = args[1];
            slingUser = args[2];
            slingPassword = args[3];
            url = args[4];
        } else {
            throw new Exception("Can't execute Hibernate install!\nPlease specify five arguments.");
        }

        StringBuilder mvnCmd = new StringBuilder();
        mvnCmd.append("org.apache.sling:sling-maven-plugin:2.4.2:install-file");
        mvnCmd.append(" -Dsling.user=" + slingUser);
        mvnCmd.append(" -Dsling.password=" + slingPassword);
        mvnCmd.append(" -Dsling.url=" + url);
        mvnCmd.append(" -Dsling.deploy.method=WebConsole");
        mvnCmd.append(" -Dsling.file=");
        mvnCmd.append(bundleFolder);
        mvnCmd.append("/");

        // Read XML file with a list of the Hibernate OSGi dependencies (bundles)
        File file = new File(xmlFilePath);
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse(file);
        NodeList bundlesList = document.getElementsByTagName("bundle");

        final InvocationRequest invocationRequest = new DefaultInvocationRequest();
        // invocationRequest.setDebug(true);
        final Invoker invoker = new DefaultInvoker();

        for (int i = 0; i < bundlesList.getLength(); i++) {
            String goal = mvnCmd.toString() + bundlesList.item(i).getTextContent();
            installBundle(invocationRequest, invoker, goal);
        }
    }

    private static void installBundle(InvocationRequest invocationRequest, Invoker invoker, String goal)
            throws MavenInvocationException, CommandLineException {
        invocationRequest.setGoals(Collections.singletonList(goal));
        final InvocationResult invocationResult = invoker.execute(invocationRequest);
        if (invocationResult.getExitCode() != 0) {
            String msg = "Invocation Exception";
            if (invocationResult.getExecutionException() != null) {
                msg = invocationResult.getExecutionException().getMessage();
            }
            throw new CommandLineException(msg);
        }
    }
}

PS

如果您不需要对AEM实例具有相同依赖性的不同版本，最好避免使用OSGi <Embed-Transitive>true</Embed-Transitive>，因为它可能会引入安全性/性能/ OSGi问题-有关详细信息，请参见Embedding_Transitive_Dependencies_Into_a_Mega-Bundle_With_Maven-Bundle-Plugin。
如果您曾经决定切换到另一个ORM框架，最好使用JPA EntityManagerFactory方法，而不要使用特定于Hibernate的SessionFactory-检查https://stackoverflow.com/a/5640796/12547140。
