使用 Grails 3 进行 Hibernate 5 搜索

Question

I am using Grails 3.1.4 and I want use Hibernate-Search for full text search of my entities.

In my build.gradle I have included Hibernate 5 and Hibernate Search

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

If I add the @Indexed to one of my domain classes, I get the folling error:

ERROR org.springframework.boot.SpringApplication - Application startup failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is java.lang.NullPointerException

Is there a way to get Hibernate Search working together with Grails domain classes?

Answer 1

as a coincidence, I am currently porting the old Grails 2 Hibernate Search plugin to be compatible with Grails 3.1.x and Hibernate 5. The original author is up to merge my PR as soon as I create it. I just finished the development if you want to give it a try:

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

EDIT :

The PR is merged, I just published in on bintray, which is the new Grails 3 platform for plugins distribution. To try the new version of Grails Hibernate Search 2.0 for Grails 3.1.x / GORM 5: Add the following repository maven { url "http://idcapture.bintray.com/plugins" }

And add the following to your dependencies compile("org.grails.plugins:hibernate-search:2.0")

it should work :)

Hope it helps!

Answer 2

The Grails 3.1.4 already includes GORM 5 Suite , means that the following lines in your ' build.gradle ' file are probably redundant:

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

As far as I know, the hibernate search should work great with Grails, by using the Grails Hibernate search Plugin .

But, if you are already working with Grails 3.1.4, probably, the easiest way might be using the GORM suite (Grails Object-Relational Mapping). The GORM enables simple access to the database, remains your code clear and more readable.

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