我正在寻找显示如何将MongoDB与Hibernate集成的资源(最好是从春季开始),以便我可以在RDBMS和NoSql替代方案之间切换:有没有人有这方面的经验？
我目前正在考虑将使用Spring,GWT,Hibernate,Jackrabbit,Hibernate Search/Lucene(以及其他)的单租户基于Java的Web应用程序转换为完全成熟的SaaS风格应用程序.
我偶然发现了一篇文章,其中强调了以下7个"事物"作为对单个租户应用程序进行重要更改以使其成为SaaS应用程序:
我的问题是,是否有人使用与我列出的类似技术在SaaS /多租户应用程序中实现上述任何7项内容？在我走上正在考虑的道路之前,我希望得到关于最佳方法的尽可能多的意见.
作为一个开始,我很确定我能够很好地处理如何在模型级别处理多个租户.我正在考虑为所有表添加租户ID,然后使用Hibernate过滤器(以及Hibernate Search的全文过滤器)根据登录用户的所有查询的租户ID进行过滤.
然而,我对性能也有一些担忧,特别是当我们的租户数量增长很多时.
任何有关如何实施此解决方案的建议都将受到高度赞赏(如果这个问题有点过于开放,我会道歉).
我在一个带有spring boot 1.4.0.RELEASE的应用程序中使用hibernate.
索引的实体看起来像是:
@Entity(name = "SearchableTariffItem")
@Indexed
public class SearchableTariffItem {
public static final String ZIFFER_ANALYZER_NAME = "ZIFFER_ANALYZER";
@GeneratedValue(strategy = GenerationType.TABLE)
@Id
private Long id;
...
}
我第一次保存实体时现在收到以下警告:
2016-08-26 15:08:32.501 WARN 8476 — [apr-8080-exec-6] org.hibernate.orm.deprecation : HHH90000015: Found use of deprecated [org.hibernate.id.MultipleHiLoPerTableGenerator] table-based id generator; use org.hibernate.id.enhanced.TableGenerator instead. See Hibernate Domain Model Mapping Guide for details.
不幸的是,我不知道在哪里可以配置我的应用程序(最好是在application.yml中)来使用TableGenerator该类.
我使用以下依赖项:
我收到此错误:

<dependency …我有一个查询,它在表的大约11个字符串或文本字段上进行ILIKE,这个字段不大(500 000),但对于ILIKE显然太大,搜索查询需要20秒.数据库是postgres 8.4
我需要实现这个搜索更快.
我想到了什么:
我从需要搜索的所有列中组装了另外的TVECTOR列,并在其上创建了全文索引.全文搜索非常快.但是......我无法在我的.hbms中映射这个TVECTOR类型.所以这个想法下降了(无论如何我更多地将它作为临时解决方案).
Hibernate搜索.(今天第一次听到它)它看起来很有希望,但我需要经验丰富的意见,因为我不想进入新的API,可能不是最简单的,因为可以做得更简单.
Lucene的
在任何情况下,这个表现在已经发生了,但我希望解决方案更通用,并应用于与全文搜索相关的未来案例.
所有建议都表示赞赏!

<persistence-unit name="graphdb" transaction-type="JTA"> …我正在研究针对我们的数据库提供更好搜索功能的机制.它目前是一个巨大的瓶颈(导致长期查询损害了我们的数据库性能).
我的老板想让我看看Solr,但经过仔细观察,似乎我们真的想要一些与Lucene本身的数据库集成机制.
从Lucene FAQ中,他们推荐使用Hibernate Search,Compass和DBSight.
作为我们当前技术堆栈的背景,我们在Tomcat上使用直接JSP,没有Hibernate,在其上没有其他框架......只针对DB2数据库直接使用Java,JSP和JDBC.
鉴于此,似乎Hibernate Search可能更难以集成到我们的系统中,尽管在这样的集成之后可以选择使用Hibernate.
有没有人可以使用其中一种工具(或其他类似的基于Lucene的解决方案)分享可能有助于选择合适工具的经验？
它需要是一个FOSS解决方案,理想情况下将自动更新来自数据库的更新Lucene(尽管有效),而无需额外的努力在更改时通知工具(否则,似乎滚动我自己的Lucene解决方案将只是一样好).此外,我们有多个应用程序服务器只有一个数据库(+故障转移),因此如果能够轻松地无缝地使用所有应用程序服务器的解决方案,那就太好了.
我现在继续检查选项,但是利用其他人的经验会非常有帮助.
我有一个执行基于给定的输入标题字段搜索的搜索框,让用户建议先从文字是基于Lucene和Hibernate Search的inserted.It所有可用的标题.它一直工作,直到输入空间.然后结果消失了.例如,我希望"学习H"给我"学习Hibernate"作为结果.但是,这不会发生.你能告诉我我应该在这里使用什么呢？

QueryBuilder qBuilder = fullTextSession.getSearchFactory()
.buildQueryBuilder().forEntity(LearningGoal.class).get();
Query query = qBuilder.keyword().wildcard().onField("title")
.matching(searchString + "*").createQuery();
BooleanQuery bQuery = new BooleanQuery();
bQuery.add(query, BooleanClause.Occur.MUST);

public …我想知道是否有任何方法可以在运行时获取类的注释信息？因为我想获得sepcifily注释的属性.
例:
class TestMain {
@Field(
store = Store.NO)
private String name;
private String password;
@Field(
store = Store.YES)
private int age;
//..........getter and setter
}
注释来自hibernate-search,现在我想要的是将"TestMain"的哪个属性注释为"字段"(在示例中,它们是[name,age]),并且"存储"( store = store.yes)'(在示例中,它们是[ age ])在运行时.
有任何想法吗？
