java - Wildfly 17 上的休眠 ogm infinispan @manytoone 双向问题

Question

当我将 infinispan ogm 与文件存储配置一起使用时，我遇到了一个问题。我的问题如下。我在 wildfly 17 上部署了一个非常小的 REST 应用程序，能够持久保存和读取非常简单的数据模型。数据模型由双向多对一关联组成。

@Entity
public class Foo {
    @Id
    private String id;

    private String name;

    @OneToMany(cascade = CascadeType.ALL , orphanRemoval = true, mappedBy = "foo")
    private List<Bar> bars = new ArrayList<>();

    public void addBar(String name) {
        Bar bar = new Bar();
        bar.setName("Bar_"+name);
        String id_foo = "Foo_" + name + "_id";
        String id_bar = "Bar_" + id_foo;
        bar.setId(id_bar);
        bars.add(bar);
        bar.setFoo(this);

   //getter and setter
}
@Entity(name = "Bar")
public class Bar {

    @Id
    private String id;

    private String name;

    @ManyToOne
    private Foo foo;

    }

}

public class FooBarService {

    @Inject
    protected EntityManager entityManager;

    @Transactional
    String persisitFoo(String name) {


        Foo foo = new Foo();
        String id_foo = "Foo_" + name + "_id";
        foo.setId(id_foo);
        foo.setName("Foo_"+name);

        //add a bar
        foo.addBar(name);

        entityManager.persist(foo);
        entityManager.flush();

        Foo result = entityManager.find(Foo.class, id_foo);
        return result.toString();
    }

    @Transactional
    String getBar(String name) {

        String id_foo = "Foo_" + name + "_id";
        String id_bar = "Bar_" + id_foo;

        // build the EntityManagerFactory as you would build in in Hibernate ORM

        Bar result = entityManager.find(Bar.class, id_bar);
        entityManager.flush();

        return result.toString();
    }

    @Transactional
    String getFoo(String name) {


        String id_foo = "Foo_" + name + "_id";

        // build the EntityManagerFactory as you would build in in Hibernate ORM

        Foo result = entityManager.find(Foo.class, id_foo);
        entityManager.flush();

        return result.toString();
    }

当我坚持一个 Foo （由一个 Bar 组成）时，我可以 getFoo 并且 Foo 对象包含一个 Bar ，但是当我在获得 Foo 对象时重新启动其余应用程序时，我失去了 Bar 关联。当我得到 Bar 对象时，存在与 Foo 对象的关联。这是我的应用程序 presistence.properties 的配置（我使用生产者以编程方式构建基于 HibernateOgmPersistence 的 entityManager）。似乎双向仅以一种方式起作用

hibernate ogm 使用的版本是

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.hibernate.ogm</groupId>
                <artifactId>hibernate-ogm-bom</artifactId>
                <version>5.4.1.Final</version> 
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

请注意， 我已经使用 mongodb 更改了提供程序，并且它运行良好。

hibernate.ogm.datastore.provider=mongodb
hibernate.ogm.datastore.host:127.0.0.1:27017
hibernate.ogm.datastore.database:ems
hibernate.ogm.datastore.create_database:true
