Hibernate Search 6与多租户问题，HSEARCH000520，HSEARCH600029

我正在用Hibernate（参考）测试Hibernate Search 6多租户，并收到错误消息“HSEARCH000520:Hibernate Search在引导过程中遇到故障”，以及其他详细信息， “HSEARCH600029:后端配置无效：索引‘Users’需要多租户，但未设置多租户策略”

我申请我的用户实体。这是Users实体类

@Indexed
public class Users implements Serializable {

    private static final long serialVersionUID = 1L;
 

    @JsonbTransient
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID")
    private Integer id;
    @FullTextField(analyzer = "name", projectable = Projectable.YES)
    @Size(min = 3, max = 50)
    @Column(name = "username")
    private String username;
    @Size(max = 50)
    @Column(name = "email")
    private String email;
    
    ...
    
}

和persistence.xml

  <persistence-unit name="jakartaEEPU" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>java:app/jdbc/myDS</jta-data-source>

    <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
    <properties> 
      <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
      ...
      <property name="hibernate.cache.use_query_cache" value="true"/>
      <property name="hibernate.cache.use_second_level_cache" value="true"/>

      <property name="javax.persistence.schema-generation.database.action" value="none"/>
      <property name="hibernate.multiTenancy" value="DATABASE"/>
      <property name="hibernate.tenant_identifier_resolver" value="com.dao.multitenancy.DatabaseTenantResolver"/>
      <property name="hibernate.multi_tenant_connection_provider" value="com.dao.multitenancy.DatabaseMultiTenantProvider"/>
    </properties>
  </persistence-unit>

org.hibernate.jpa.HibernatePersistenceProvider

此实体类中是否缺少或不正确？

您需要在后端明确选择多租户策略。只需将此属性添加到您的

persistence.xml

：

      <property name="hibernate.search.backend.multi_tenancy.strategy" value="discriminator"/>

看

编辑：我创建它是为了尝试更改这个毫无帮助的错误消息。

谢谢。它能用。@PeterL355没问题。不要忘记将解决方案标记为已接受，这样可以帮助其他人更容易地发现它。
