Spring Boot, Hibernate Search properties

Question

How to provide Hibernate Search parameters when using Spring Boot?

...
spring.datasource.driverClassName=org.postgresql.Driver

hibernate.search.jmx_enabled=true
hibernate.search.default.directory_provider=filesystem
hibernate.search.generate_statistics=true
hibernate.search.lucene_version=LUCENE_CURRENT
hibernate.search.default.indexBase=/mypath-to-index

It does not care what I provide. Default settings always get applied.

I think below code does not have anything to process properties related to Hibernate Search. Can that be the issue?

Where are those properties? – Benignant

inside application properties file, at src/main/resources. Other jpa and datasource settings get evaluated fine. – Lillie

Answer 1

You can put them in the application.properties file if you put "spring.jpa.properties." in front of the property names.

Example:

spring.jpa.properties.hibernate.search.jmx_enabled=true
spring.jpa.properties.hibernate.search.default.directory_provider=filesystem
spring.jpa.properties.hibernate.search.generate_statistics=true
spring.jpa.properties.hibernate.search.lucene_version=LUCENE_CURRENT
spring.jpa.properties.hibernate.search.default.indexBase=/mypath-to-index

Spring will take any properties under spring.jpa.properties.* and pass them along (with the prefix stripped) once the EntityManagerFactory is created.

Great! This is the cleanest solution and it is more in the way of Spring Data JPA (see here). – Mares

Answer 2

Got it working.

Put another property file named "hibernate.properties" inside src/main/resources with below content.

hibernate.search.jmx_enabled=true
hibernate.search.default.directory_provider=filesystem
hibernate.search.generate_statistics=true
hibernate.search.lucene_version=LUCENE_CURRENT
hibernate.search.default.indexBase=/mypath-to-index
