用Grails 3搜索Hibernate 5

Question

我使用Grails 3.1.4，我希望使用Hibernate-搜索我的实体的全文搜索。

在我的build.gradle中，我包含了Hibernate 5和Hibernate搜索。

compile "org.hibernate:hibernate-core:5.0.9.Final"
compile "org.hibernate:hibernate-ehcache:5.0.9.Final"
compile "org.hibernate:hibernate-search-orm"

如果我将@Indexed添加到我的一个域类中，就会得到折叠错误：

ERROR org.springframework.boot.SpringApplication - Application startup failed

有没有办法让Hibernate搜索与Grails域类协同工作？

Answer 1

巧合的是，我目前正在移植旧的Grails 2 Hibernate搜索插件，使其与Grails 3.1.x和Hibernate 5兼容。如果你想试一试的话，我刚刚完成了它的开发：

https://github.com/lgrignon/grails-hibernate-search-plugin

编辑

PR是合并的，我刚刚发表在上绑定，这是新的Grails 3平台插件分发。要尝试GrailsHibernateSearch2.0forGrails3.1.x/ GORM 5的新版本:添加以下存储库maven { url "http://idcapture.bintray.com/plugins" }

并将以下内容添加到依赖项compile("org.grails.plugins:hibernate-search:2.0")中

它应起作用:)

希望能帮上忙！

Answer 2

Grails 3.1.4已经包含了'build.gradle‘，这意味着您的GORM 5套房文件中的以下行可能是多余的：

compile "org.hibernate:hibernate-core:5.0.9.Final" 
compile "org.hibernate:hibernate-ehcache:5.0.9.Final"
compile "org.hibernate:hibernate-search-orm"

据我所知，通过使用Grails Hibernate搜索插件，hibernate搜索在Grails中应该运行得很好。

但是，如果您已经在使用Grails3.1.4，那么最简单的方法可能是使用GORM套房 (Grails对象-关系映射)。GORM支持对数据库的简单访问，保持代码的清晰性和可读性。

如果您使用的是"org.hibernate: Hibernate -core:5.0.9.Final“，那么您需要获得Hibernate搜索："org.hibernate:hibernate-search-orm:5.5.4.Final".的兼容版本。
